What is SRE?

In general, an SRE team is responsible for the availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning of their service(s).
SRE is fundamentally doing work that has historically been done by an operations team, but using engineers with software expertise, and banking on the fact that these engineers are inherently both predisposed to, and have the ability to, design and implement automation with software to replace human labor.

DevSecOps:

In DevSecOps, the developer must involve themselves with operation and security teams in the early stages of design and development processes to facilitate secure applications.

DevOps Vs SRE Vs DevSecOps:

DevOps and DevSecOps follow a blameless culture approach where every mistake is a learning opportunity. Instead of making the system fault-proof, DevOps culture focuses on a fault-tolerant approach. DevOps and DevSecOps basically deal with the pre-failure situation.

On the other hand, SRE methodology practices a blameless postmortem approach wherein every time failure occurs, the blameless postmortem approach identifies what caused the fault and finds ways to avoid it in the future. SRE basically deals with the post-failure situation.

2. DevOps is meant to reduce the friction between development and operation teams in order to reduce time to market for application and to improve overall customer success.

3. DevOps tools include:

1. Linux
2. Git and GitHub
3. Maven

Definitions:

DevOps – DevOps is the change in culture and practices of the SDLC process which enable the organization to produce high-quality software and continuously deliver the software. It has been originated from two words, Dev and Ops. DevOps has some phases through which it works. DevOps is the collaboration between development and operation teams to ensure continuous integration, development, test, deployment, and monitor. After DevOps came the development and operation team is no longer working as ‘siloed’. DevOps is much better and faster than any other traditional model in the current era because it has removed the vulnerabilities between culture ad practices which was stopping other organizations to keep up with the time which was demanding a faster and reliable process.

DevSecOps – DevSecOps is for development, security, and operations. Its main motto is to make every employee working under a project consider security policies also important like other works, so the product will be saved. DevSecOps is all about security measures from the development phase to the monitor phase. Organizations can implement DevSecOps to break down silos between development, security, and operations so they can maintain the proper security over their products. DevSecOps uses some security testing tools to integrate into their CI/CD process like –
⦁ Static application security testing (SAST)
⦁ Software composition analysis (SCA)
⦁ Interactive application security testing (IAST)
⦁ Dynamic application security testing (DAST)

SRE – SRE has been originated from google company. SRE’s main aim is to solve the operational problems right from testing to monitoring software when it is deployed in the market. The main focus of creating it was to remove the vulnerabilities of operation parts to make the product effective and reliable. It removed the ‘silos’ from all departments and made the operation teams work together to produce an efficient product, e.g – Somewhere you might have experienced you have never felt any downtime (the app is not working properly) on your Google apps even when Google teams are pushing updates over that particular app. This is like the SRE team works making your apps more trustworthy without making you feel any disturbance. SRE works with the collaboration of software engineers. SRE somewhere automates Its operation tasks and accelerate software delivery with minimizing risks.

Site reliability engineering (SRE) is rapidly becoming more important to organizations that need to scale IT operations while maintaining or improving reliability and security, and to modernize operations to match the growth of DevOps in the organization. Without sufficiently thorough consideration given to best practices for people, processes and technologies, the transformation from traditional IT operations to SRE is unlikely to succeed. Despite challenges, the transformation to SRE is compelling because it provides an opportunity to reduce total operations costs and improve security and reliability while scaling services.

To be successful, IT leaders need a comprehensive understanding of SRE best practices and need a well-engineered, yet affordable strategy and road map that effectively implements best practices and balances the many aspects needed to transform people, proces and technology. A Strategic SRE Assessment approach, based on best practices, is a key tool to help leaders understand, obtain the strategy and create a road map that will successfully transform traditional IT operations to SRE.

There is no “standard” SRE assessment approach in the industry. This article enumerates a practical and proven Strategic SRE Assessment approach. The heart of the Strategic SRE Certification Assessment approach is a survey of SRE best practices categorized under nine pillars: Culture, Work Sharing, Toil Reduction, SLAs/SLOs/SLIs, Measurements, Anti-Fragility, Deployments, Performance Management and Incidents Management. The survey is used to collect importance and capability scores for each of the SRE practices. As part of the assessment, a survey determines the current state and preferences of SRE practices for an organization for each of the nine SRE pillars.

The following are examples of best practices for each pillar that are part of the Strategic SRE assessment survey:

Culture – Leaders need to understand and sponsor a clear vision for SRE.

The culture embraces working practices to proactively shifts left the “Wisdom of Production.”
The culture encourages learning from failure and continuous improvement.
The SRE role is clearly defined and understood and SREs are considered a vital part of the organization.
Rules of engagement and principles for how SRE teams interact with their environment are codified—not only the production environment but also the product development teams, testing teams, users and so on. Those rules and work practices help to maintain SRE focus on engineering work as opposed to operations work.
Work Sharing – Successful SRE requires that work be shared between SRE teams and development.

SRE teams are composed of software developers with strong operations knowledge or IT operations people with strong software development skills.
SRE workloads are managed to a budget with typically 50% or less spent on operations work.
SRE on-call work budgets are typically 25% or less. Developers share on-call work.
Technical debt is worked in small increments.
Toil Reduction – SREs work to reduce non-value-added work through automation and standards.

Work standardization and automation—of both tools and processes—is employed to improve scalability, repeatability and other important goals.
Work standardization is used to reduce time spent on non-value-added work.
Automation is used to reduce time spent on non-value-added work.
SLAs/SLOs/SLIs – Service level metrics, based on user perspectives, combined with error budget policies, are critical to managing flow and reliability.

SLOs are selected to measure availability, performance and other metrics in terms that matter to an end user.
An error budget (= 1-availability) internal service level objective (SLO) is established for each service. SLOs are set to be more stringent than external service level agreements (SLAs) promised to customers. The SLO budget considers what level users will accept, alternatives for users who are dissatisfied, and usage patterns of the product at different availability levels.
An error budget policy prescribes consequences if an error budget is spent. For example, the service freezes changes (except urgent security and bug fixes addressing any cause of the increased errors) until either the service has earned back room in the budget or the count period resets.
Measurements – Smart monitoring implements observability to accelerate response times to incidents.

Monitoring solutions are designed to produce service level indicators (SLIs) from which SLOs can be calculated automatically.
SLIs do not require a human to interpret an alerting domain. Instead, software observability algorithms do the interpreting, and humans are notified only when they need to act.
Monitoring systems use telemetry and instrumentation to ensure the data being monitored is accurate, relevant and available in real-time.
Anti-Fragility – Systems of people, processes and technologies are continuously tested and improved to assure they are resilient enough to serve applications as they scale.

Anti-fragility strategies are practiced to proactively assure the resilience of applications, infrastructures and pipeline services.
Fire drills are periodically conducted to proactively determine weaknesses in systems of people, processes and technologies that could potentially impact SLOs.
Chaos monkey or equivalent infrastructure testing strategies are used to proactively determine weaknesses in infrastructure systems that could potentially impact SLOs.
Security testing and DevSecOps practices reduce the risk of security vulnerabilities.
Deployments – Deployment strategies reduce the risk of deployment failures.

Non-emergency deployments use progressive rollouts in which changes are applied to small fractions of traffic and capacity at one time. If unexpected behavior is detected, the changes are rolled back first and diagnosed afterward to minimize mean time to recovery.
Automation is used to implementing progressive rollouts, detect problems and implement rollback changes safely when problems arise, because outages are primarily caused by changes in a live system.
Deployment strategies such as blue-green, feature flag rollouts, A/B testing and canary rollouts are used to reduce the blast radius of failed deployments.
Performance Monitoring – Proactive testing and monitoring ensure applications and infrastructures have the capacity necessary to flex and scale when needed.

The SRE team is responsible for provisioning and monitoring utilization because utilization is a function of how a given service works and how it is provisioned.
The SRE team is responsible for capacity planning and provisioning. Regular load testing of the system is used to correlate raw capacity (servers, disks and so on) to service capacity.
Provision to handle a simultaneous planned and unplanned outage without making the user experience unacceptable. This results in an “N + 2” configuration, in which peak traffic can be handled by N instances (possibly in degraded mode) while two instances are unavailable.
Incident Management – Incidents are managed in an efficient, blameless manner with a goal to use incidents to improve responses.

Playbooks record the best practices for human response actions because playbooks produce roughly a 3x improvement in mean time to recovery.
Emergency response performance is measured using mean time to repair (MTTR) metrics instead of mean time to failure (MTTF) because the most relevant metric in evaluating the effectiveness of emergency response is how quickly the response team can bring the system back to health—that is, the MTTR.
Postmortems are blameless and focus on process and technology, not people.
Postmortems are conducted for significant incidents regardless of whether they resulted in a page; postmortems that did not trigger a page are even more valuable, as they likely point to clear monitoring gaps. Find all root causes of the event and assign actions to correct the problem or improve how it is addressed next time.
SRE Assessment Surveys Are Not Enough
The survey alone is an essential tool to collect information about the current state and preferences for each of the SRE practices. However, this is only part of the comprehensive Strategic SRE Assessment approach.

The Strategic SRE Assessment approach starts with workshops to get alignment between leaders and teams regarding big-picture goals prior to conducting the survey. This is necessary so that everyone who answers the survey has a common perspective and can better respond with considered views of importance and capability scores for each of the practices. The results of the survey include an analysis that points out specific pillars and individual practices that have a high gap score in which the practices are scored as important but not yet practiced well. The high-priority gaps are then used to organize a value-stream map working session, that is designed to find the highest priority bottlenecks in people, processes and technology bottlenecks in the value steam, relative to the organization’s goals and gaps. With the goals, gaps, and data from the value stream map in hand, the next step is to formulate an implementation road map that directly addresses the goals, gaps and bottlenecks in the value stream.

The final step is to obtain strategic alignment of the big-picture plan by reviewing the findings and road map with the leadership and implementation teams. This entire Strategic SRE Assessment approach, from goal alignment through surveys, value stream mapping, road map creation and strategic alignment, varies depending on several factors such as the size of the organization, number of applications and size of the deployment domains to be included in the assessment.

A Rapid Strategic SRE Assessment for a sample set of model applications typically is conducted in 21 days. More complex Strategic SRE assessments involving many applications may take up to 90 days.

In most cases the Rapid Strategic SRE Assessment is the best place to start. Most often, it is not a good idea and is too expensive to “boil the ocean” and make changes across all applications and deployment domains at once. By starting with a small number of model applications, it is easier to implement, measure and demonstrate success and use the results at each step to justify ongoing investments needed to complete the transformation across the organization. Another advantage of the Rapid Strategic SRE Assessment is that it is a quick and affordable approach to check-point progress as SRE is implemented progressively across applications and deployment domains.

Key Takeaways for SRE Transformation Leaders
SRE offers immense value for modernizing and scaling IT operations reliably and securely and to complement DevOps transformation. Adherence to SRE best practices is essential to reduce risk and assure security as the transformation is implemented.

Each organization is different and has different requirements and priorities for its applications and deployment domains. The specific SRE practices that are the highest priority vary according to the priorities of applications and deployment domains. The Rapid Strategic SRE assessment approach, based on nine pillars of SRE best practices, is quick, effective and affordable.

The Rapid Strategic SRE Assessment is a preferred approach to kick-start the SRE transformation. This approach is also a preferred and affordable tool to reassess the direction as SRE is implemented progressively across the organization.

The widespread shift to remote and distributed work has further widened the gap. Distributed teams rely more heavily on asynchronous collaboration tools, make more frequent changes to shared code bases, and must integrate work across more diverse environments—all of which demands a broader and more fluid skill set than a co-located team might require.

Organizations that successfully close the IT skills gap can accelerate their transformation efforts and build the organizational resilience needed to weather future disruptions. Doing so requires three things: understanding why specific skills are rising in demand, selecting tools that reduce the burden of constant retraining, and cultivating a lasting culture of learning.

Why These Skills Are Rising in Demand

Before investing in any upskilling program, it pays to understand the forces driving skill requirements. Without that context, training budgets get wasted on skills that may fade from relevance quickly.

Governance, Risk, and Compliance (GRC)

The surge in demand for GRC skills is a direct consequence of an increasingly complex regulatory landscape. Regulations such as the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) require that privacy and risk controls be woven into software from the ground up—not bolted on after deployment. DevOps teams do not necessarily need to become legal experts, but they do need to internalize privacy-by-design and security-by-design philosophies. Developers who understand data classification, consent management, and audit logging are better equipped to ship compliant software without depending entirely on specialist compliance teams at release time.

Process and Knowledge Skills

The growing emphasis on process and knowledge skills tracks closely with the broader adoption of Site Reliability Engineering (SRE) practices. SRE introduces discipline around service-level objectives, error budgets, alert monitoring, and escalation runbooks—all of which demand explicit process thinking. Engineers who invest in understanding on-call workflows, incident response playbooks, and blameless postmortem practices will find these skills increasingly transferable across organizations as SRE continues to mature.

Collaboration and Integration Skills

As distributed teams become the norm, the ability to collaborate effectively through asynchronous tooling matters more than ever. Higher volumes of pull requests, code reviews, and merge conflicts are practical indicators that teams need stronger skills in version control workflows, branch strategies, and CI/CD pipeline hygiene. These are not glamorous skills, but they compound in value as team size and code base complexity grow.

Choosing Tools That Reduce Skill Variability

Because in-demand skills can shift from year to year, organizations that build their workflows around tools requiring constant retraining face an uphill battle. A more sustainable approach is to invest in tools that abstract away repetitive complexity and remain stable across different environments.

• Container orchestration for multi-cloud portability: Many organizations now run workloads across multiple cloud providers to maximize availability and avoid vendor lock-in. Container-based workflows—using platforms such as Kubernetes—let teams deploy consistently across cloud environments without needing deep provider-specific expertise for every project. This reduces the surface area of skills that must be maintained per cloud vendor.
• Automation for compliance and governance tasks: Manual compliance checks, data-privacy audits, and risk assessments are time-consuming and error-prone. Tools that automate policy enforcement, audit trail generation, and vulnerability scanning let engineers focus on product work rather than on learning the specifics of each regulatory framework by hand.
• Low-friction CI/CD pipelines: Pipelines that are well-documented, version-controlled, and designed with sensible defaults lower the learning curve for new team members and reduce the cognitive overhead of onboarding to new projects.

The principle here is straightforward: every task that a tool can handle reliably is a task that no longer needs to be a human skill requirement. This does not eliminate the need for upskilling, but it does let engineers concentrate their learning energy on higher-order, durable capabilities.

Building a Sustainable Culture of Learning

Technology alone cannot close the skills gap. Organizations also need deliberate cultural practices that encourage continuous learning, even—and especially—in distributed or remote environments where informal knowledge transfer is harder to facilitate.

Leadership Commitment

Learning culture starts at the top. Engineering managers and department leaders who actively protect time for training—blocking out hours for online courses, funding conference attendance, and visibly participating in learning themselves—signal that skill development is a legitimate use of work time, not something engineers must squeeze into personal hours. Without this signal, upskilling programs often atrophy despite good intentions.

Structured Learning Events

Ad hoc learning is valuable but insufficient on its own. Structured events create shared context and reinforce a team-wide growth mindset. Consider incorporating:

• Internal hackathons: Time-boxed, problem-focused events that encourage engineers to experiment with unfamiliar tools or domains in a low-stakes setting. Hackathons reinforce agile thinking and surface creative solutions that routine project work rarely produces.
• Tech talks and internal demos: Short, regular sessions where team members share what they have learned—from a conference talk, a new library, or a post-incident review—democratize knowledge and reduce information silos.
• Blameless postmortems: Beyond their operational value, postmortems are a structured learning mechanism. Reviewing what went wrong, why, and how processes will change transforms incidents into durable institutional knowledge.
• Mentorship pairing: Pairing senior engineers with less experienced colleagues on specific skills—even asynchronously—accelerates knowledge transfer in ways that courses alone cannot replicate.

Continuous Process Inspection

Agile and DevOps both emphasize continuous improvement, and this principle applies equally to the learning process itself. Teams that regularly reflect on which skills are proving most valuable, which training investments delivered results, and where knowledge gaps are causing friction will be better positioned to adapt their upskilling strategy as requirements evolve.

A People-Process-Technology Framework for Closing the Gap

Closing the DevOps skills gap is not a one-time project. Technologies such as multi-cloud infrastructure and edge computing are maturing rapidly, and each wave of adoption brings new skill requirements in its wake. Organizations that treat upskilling as a sustained, strategic priority—rather than a reactive response to individual job vacancies—will build more adaptable engineering organizations over time.

The practical path forward combines three elements working in concert:

1. People: Invest in individuals through structured learning programs, mentorship, and leadership that models continuous development.
2. Process: Embed learning into everyday workflows through postmortems, retrospectives, and structured knowledge sharing.
3. Technology: Select tools that reduce skill complexity and automate repetitive tasks, freeing engineers to focus on durable, high-value capabilities.

Simply telling developers to learn new skills without explaining why those skills matter—or without providing the time, resources, and tooling to support that learning—is a short-sighted and ultimately ineffective approach. The organizations most likely to thrive are those that understand the root causes of shifting skill requirements and equip their teams accordingly, building not just competency for today, but adaptability for whatever comes next.

The insights in this article draw on perspectives shared by Rob Hernandez, CTO of Nebulaworks, on breaking into the SRE field.

What Is a Site Reliability Engineer?

The SRE role grew out of the senior systems administrator discipline. Where a traditional sysadmin resolves issues manually and reactively, an SRE approaches operational problems the way a software engineer approaches application development — by writing code to automate away toil and prevent recurrence.

SREs typically own service reliability targets (expressed as Service Level Objectives), manage error budgets, and respond to on-call incidents. When a production outage happens at 3 a.m., the SRE is the one getting paged.

SRE Salary Range

According to Glassdoor data cited in the original source, SRE salaries range from approximately $82,000 to $150,000 per year in the United States. Actual compensation varies significantly by location, company size, cloud platform expertise, and years of experience. Check current listings on Glassdoor, Levels.fyi, or LinkedIn for up-to-date figures in your market.

Core Skills Required for an SRE Role

1. Programming and Software Engineering Fundamentals

SREs write code. The automation scripts, tooling, and infrastructure-as-code that keep systems running are developed using the same practices a software engineer uses to build a product. You should be fluent in at least one general-purpose language — Python, Go, and Java are common — and comfortable with:

• Git source control — committing changes, branching strategies, and submitting pull requests for peer review should be second nature.
• Code review — you will frequently need to read and reason about code you did not write. Resist the instinct to discard existing solutions without understanding why they were built the way they were; historical context matters.
• Infrastructure as Code (IaC) — familiarity with tools such as Terraform, Ansible, or Pulumi is increasingly expected.

2. Networking and the OSI Model

Distributed systems rely entirely on the network. When an alert fires at 3 a.m., you need to know which layer of the OSI model to investigate first. At minimum, understand:

• Layer 1–2 (Physical and Data Link) — hardware, switches, MAC addressing
• Layer 3 (Network) — IP routing, subnetting, BGP basics
• Layer 4 (Transport) — TCP vs UDP, connection state, port management
• Layer 7 (Application) — HTTP, DNS, TLS, load balancing

Being able to pinpoint whether an outage is a DNS resolution failure, a routing issue, or a saturated NIC is a critical diagnostic skill that separates senior SREs from generalists.

3. Systems Engineering and Linux Proficiency

Most production infrastructure runs on Linux. You should be comfortable at the command line: managing processes, reading logs, understanding the filesystem hierarchy, writing shell scripts, and diagnosing resource contention (CPU, memory, disk I/O, network).

4. Observability and Incident Management

Modern SRE practice centers on observability — the ability to infer system state from telemetry. Familiarity with monitoring (Prometheus, Datadog), logging (ELK stack, Splunk), and tracing (Jaeger, OpenTelemetry) is highly valued. Understanding SLIs, SLOs, and error budgets demonstrates that you think about reliability as an engineering problem, not just an operational one.

How to Stand Out in an SRE Interview

Contribute to Open Source

Open-source contribution is one of the most effective ways to demonstrate SRE-relevant skills. Working in a large codebase you didn’t create, coordinating with contributors you’ve never met, and following a project’s contribution guidelines mirrors real SRE work directly. Find a project related to infrastructure, observability, or automation that you care about, start with small fixes, and build from there. Document this work on your resume and link to your GitHub profile.

Research the Team’s Problems Before You Interview

Before your interview, ask the hiring manager whether they can share examples of real problems the team is working on. If they’re willing to discuss them, prepare high-level approaches to those problems and bring those ideas into the conversation. You won’t have all the context, but showing that you can think critically and propose solutions before you’ve even joined — using only publicly available information and reasonable assumptions — signals the kind of proactive, engineering-driven mindset SRE teams value.

Build a Home Lab or Cloud Environment

Hands-on experience is irreplaceable. Set up a Kubernetes cluster, instrument it with Prometheus and Grafana, deliberately break things, and practice diagnosing failures. Document what you learn. Interviewers frequently ask scenario-based questions, and having real war stories — even from a home lab — is far more convincing than theoretical knowledge alone.

Sample SRE Interview Questions and Answers

The following are representative questions that test networking and Linux fundamentals — common in SRE technical screens.

Q: What is the difference between a hub and a Layer 2 switch?

A: A hub is a Layer 1 device that broadcasts all incoming packets to every connected port, regardless of the destination. This creates unnecessary traffic and collisions. A Layer 2 switch, by contrast, maintains a MAC address table. When a frame arrives, the switch looks up the destination MAC address and forwards the frame only to the specific port associated with that address — far more efficient and scalable.

Q: What is the PATH environment variable in Linux, and how would you append to it?

A: $PATH is a colon-delimited list of directories that the shell searches when you type a command. When you run python3, for example, the shell looks through each directory in $PATH in order until it finds an executable named python3. Without $PATH, you would need to type the full path (e.g., /usr/bin/python3) every time.

To append a directory — say, /opt/mytools/bin — to your current session:

export PATH=$PATH:/opt/mytools/bin

To make the change persistent across sessions, add the same line to your shell’s initialization file (~/.bashrc, ~/.bash_profile, or ~/.zshrc depending on your shell).

Q: How would you diagnose a service that is intermittently unreachable?

A: This is a common scenario-based question. A structured approach might be:

1. Confirm the symptom — is it DNS resolution, TCP connection, or application-level failure?
2. Check health and readiness of the service itself (process running, listening on the expected port).
3. Review recent deployments or configuration changes.
4. Examine logs at the application, load balancer, and network levels.
5. Check resource saturation — CPU, memory, file descriptors, connection pool limits.
6. Use tools like ping, traceroute, curl -v, netstat, and tcpdump to isolate the layer where the failure occurs.

Getting Certified as an SRE

Several professional certifications can help validate SRE knowledge, including the SRE Certified Professional (SRECP) offered by DevOps School. Cloud provider certifications (AWS, GCP, Azure) focusing on operations and reliability are also recognized by hiring teams. Certifications complement hands-on experience but rarely replace it in technical interviews.

Summary: Your SRE Job Search Checklist

• ☐ Learn at least one programming language (Python or Go are common SRE choices)
• ☐ Master Git workflows: branching, pull requests, code review
• ☐ Understand all seven layers of the OSI model and common networking protocols
• ☐ Build Linux command-line proficiency and scripting skills
• ☐ Get hands-on with Kubernetes, Prometheus, and infrastructure-as-code tools
• ☐ Contribute to at least one open-source project and document it on your resume
• ☐ Research the team’s existing pain points before your interview
• ☐ Practice incident diagnosis scenarios out loud, as you would in a real on-call situation

The Core Challenge: Too Much Data, Too Little Time

Modern IT teams operate under an uncomfortable contradiction. The systems they maintain have become business-critical — when apps go down, revenue disappears and customers churn — yet the sheer volume of telemetry data those systems generate has made manual monitoring impractical. Mainframes gave way to distributed computing, which gave way to virtualisation, which gave way to microservices and ephemeral containers. Each transition multiplied the number of signals an operations team must interpret.

Legacy monitoring tools were designed for simpler, more static environments. Today they produce an overwhelming flood of alerts, most of which are noise, while the genuinely actionable signals are buried underneath. The result: teams spend more time reacting to emergencies than building new capabilities, agility stalls, and innovation shrinks.

How DevOps Tried to Solve the Problem

The DevOps movement tackled this challenge by re-centering ownership. Rather than handing off services to a centralised operations team with little product context, DevOps places responsibility for reliability, deployment, and support directly on the engineers who write the code. This decentralises operations into smaller, empowered squads, each accountable for its own microservice and its contribution to the overall customer experience.

Many organisations complement this model with a Site Reliability Engineering (SRE) function. SREs monitor observability data, identify potential failure modes early, and feed those insights back into the development cycle — strengthening reliability and scalability before incidents reach production.

DevOps and SRE practices represent genuine progress. However, they surface a new set of coordination problems as organisations scale.

Where DevOps Teams Still Struggle

Even well-run DevOps organisations encounter friction at the boundaries between teams and tools:

• Alert noise at scale. Each microservice emits its own telemetry. Across dozens or hundreds of services, surfacing the events that actually matter — and understanding how they relate to each other — requires significant cognitive effort.
• Unclear blast radius. When an incident occurs, understanding which downstream services and customers are affected is rarely straightforward. Teams need relationship context, not just raw metrics.
• Cross-team coordination. DevOps squads interact primarily through APIs. When a multi-service incident demands urgent collaboration from geographically dispersed teams with different on-call schedules and escalation paths, orchestrating the right response quickly is genuinely hard.
• Post-incident learning. Without a structured feedback loop, teams repeat the same investigations and make the same mistakes. Post-mortems are often rushed or skipped under the pressure of the next deployment.

These are not failures of DevOps as a philosophy — they are the natural consequences of operating at a scale that exceeds what human attention alone can manage.

What Is AIOps?

Artificial Intelligence for IT Operations (AIOps) refers to platforms that apply machine learning and data analytics to the monitoring, event correlation, and incident response workflows that operations and SRE teams depend on. The term was popularised by analyst firm Gartner, though the underlying techniques — anomaly detection, topology mapping, noise reduction, root cause analysis — have been evolving for years.

A mature AIOps platform typically provides several capabilities:

• Baseline learning. The platform observes normal behaviour across your environment over time, so it can distinguish a genuine anomaly from expected variation.
• Alert correlation and noise reduction. Related alerts from multiple sources are grouped into a single, actionable incident rather than flooding dashboards with thousands of individual events.
• Root cause identification. By mapping dependencies between services and infrastructure components, AIOps can point to the probable origin of an incident rather than simply listing its symptoms.
• Prescriptive recommendations. Drawing on historical resolution data, the platform can suggest remediation steps, shortening the time from detection to fix.
• Intelligent notification routing. The right people are engaged at the right time, respecting on-call schedules, escalation paths, and geographic constraints.
• Collaborative workspaces. Team members share a consistent, real-time view of the incident, its context, and the actions being taken.
• Post-mortem acceleration. Structured capture of resolution steps and learnings feeds future incident prediction and speeds future response.

How AIOps Complements DevOps

DevOps and AIOps are not competing philosophies. AIOps is best understood as the intelligence layer that makes DevOps practices sustainable at enterprise scale.

Cutting Through the Noise

SREs and DevOps engineers should spend their attention on meaningful signals. AIOps handles the initial filtering — correlating alerts across tools and services, suppressing duplicates, and surfacing only the events that warrant human action. Engineers engage with context, not chaos.

Closing the Gap Between Detection and Resolution

By identifying probable root causes and suggesting remediation steps drawn from previous incidents, AIOps shortens mean time to resolution (MTTR). Teams do not start each incident investigation from scratch; they begin with a working hypothesis informed by machine learning applied to historical patterns.

Orchestrating Cross-Team Response

When an incident spans multiple services and requires engineers from multiple teams, AIOps can handle the coordination logic: who is on call, what their escalation path is, which communication channel they prefer. This removes a significant manual burden from incident commanders and reduces response lag.

Building Institutional Memory

Post-mortems generate valuable data that typically lives in a document nobody reads. AIOps platforms ingest resolution steps and feedback, making that knowledge available during future incidents through predictive analysis. Repetitive problems become detectable — and preventable — before they cause outages.

Enabling Edge-Based Intelligence

For AIOps to be effective in high-volume environments, anomaly detection should happen close to where data is generated — at the edge — rather than centralising every raw event before analysis. This reduces data transport costs and latency, and allows the platform to act on local patterns without waiting for a central aggregation step.

Practical Considerations for Teams Evaluating AIOps

Organisations considering an AIOps investment should evaluate platforms against a few practical criteria:

• Integration breadth. An AIOps platform is only as useful as the data it can ingest. Look for broad, well-maintained integrations with your existing monitoring, logging, tracing, ITSM, and communication tools.
• Time to value. Machine learning models need training data. Understand how long a platform takes to learn your environment before it produces useful signal, and what the experience looks like during that ramp-up period.
• Explainability. Engineers need to trust the platform’s recommendations. Opaque black-box correlations are harder to act on and harder to validate. Prefer platforms that can explain why they grouped events or suggested a remediation step.
• Feedback loops. The platform should improve as your team provides feedback — marking correlations as incorrect, flagging missed incidents, confirming root cause assessments. Without this loop, the model stagnates.
• Organisational readiness. AIOps adoption is a cultural and process change as much as a technical one. Teams need to trust automated triage enough to act on it, and to contribute structured feedback. Plan for enablement and change management.

The Bottom Line

DevOps represents a genuine and necessary evolution in how organisations build and operate software. But the scale of modern distributed systems — and the volume of observability data they produce — exceeds what human teams can manage without assistance. AIOps provides that assistance: not to replace engineers, but to remove the work that should never have required engineering judgement in the first place.

When AIOps handles noise reduction, correlation, root cause identification, and notification routing, DevOps and SRE engineers are freed to do what they do best: understand systems deeply, design for reliability, and build experiences that serve customers. That is the argument for DevOps and AIOps working together — not as competing strategies, but as complementary layers of a mature operations practice.

Why Disruption Is a Good Time to Upskill

Workplace disruption rarely feels like a career opportunity, but for DevOps professionals it can be exactly that. When teams shift to remote work, delivery pipelines are stress-tested, automation gaps become visible, and the value of a well-rounded DevOps engineer becomes undeniable to leadership. Rather than waiting for conditions to normalise, this is the right moment to take honest stock of your skills, identify gaps, and start filling them.

There was already a recognised skills and talent shortage in the DevOps field before 2020. That gap has not closed; if anything, accelerated digital transformation has widened it. Organisations that were slow to adopt DevOps practices have been forced to move faster, which increases demand for engineers who can both implement the tooling and guide the cultural change.

What the Upskilling 2020 Report Found

The DevOps Institute released its Upskilling 2020: Enterprise DevOps Skills Report based on a survey of 1,260 individuals asked to identify the skills they consider critical to DevOps and digital transformation. The central concept in the report is what the Institute calls the DevOps human: a practitioner who balances people skills, process knowledge, and technology expertise rather than excelling in only one dimension.

Jayne Groll, co-founder and CEO of the DevOps Institute, framed the challenge this way:

“While organisations are transforming toward digital operating models, challenges of speed and scale of technological advances, IT budgets, and a huge skill gap are causing a slowdown of this fourth Industrial Revolution.”

— Jayne Groll, DevOps Institute

Groll also noted that upskilling and retraining “must be high on every organisation’s agenda” — and that many organisations are actively encouraging staff to use periods of reduced project velocity to learn.

Demand for DevOps Engineers Remains Strong

Christian Mendiola, a recruitment consultant specialising in cloud computing, DevOps, and site reliability engineering (SRE) for financial services companies, observed that the DevOps job market held up better than most during periods of broader hiring slowdowns:

“Companies still need DevOps engineers in this climate. It is one of the few markets we’ve found that has been less impacted by the decrease in hiring.”

— Christian Mendiola, Huxley (SThree)

Sectors with particularly acute needs include finance, healthcare, and ad tech. Mendiola noted that industry-specific experience is less important to hiring managers than strong technology and communication skills — a point worth remembering if you are considering a sector change.

The candidate profile that stands out most, according to Mendiola, is someone who has helped build a DevOps methodology from scratch or matured one from its early stages. This demonstrates both theoretical understanding and practical execution — and shows that the candidate is more than an individual contributor.

The Technical Skills Employers Are Looking For

Jim Mercer, research director for DevOps at IDC, pointed to a clear rise in demand for specific technical competencies, especially those that support remote, automated, and highly reliable workflows:

“Prior to COVID-19, DevOps professionals were in strong demand. In the midst of the crisis, DevOps professionals are still in strong demand, but the demand for effective remote working and coding, automation, and SRE skills is higher given the ‘new normal.'”

— Jim Mercer, IDC

Mercer recommends prioritising the following technical skill areas:

• Agile software development techniques — understanding iterative delivery and cross-functional collaboration
• Developer-driven testing — shifting quality left so defects are caught early
• Highly automated test environments — reducing manual toil and enabling fast feedback loops
• CI/CD pipelines — designing, maintaining, and improving continuous integration and delivery workflows
• Infrastructure as Code (IaC) — provisioning and managing infrastructure through version-controlled configuration
• Configuration management — tools such as Ansible, Puppet, or Chef
• Monitoring, alerting, and logging — building observability into systems from the start
• Code review and coverage practices — maintaining quality gates in delivery pipelines
• Containers and orchestration — hands-on experience with Docker and Kubernetes in particular
• SRE principles — error budgets, SLOs, SLIs, and reliability engineering mindset

This is a broad list, which is intentional. The most competitive DevOps engineers are not one-trick specialists in a single tool; they understand how these technologies connect across the software delivery lifecycle.

Human Skills Are Not Optional

Technical depth alone will not differentiate you. Eveline Oehrlich, independent research director at the DevOps Institute and co-author of the Upskilling 2020 report, argues that human skills are finally being taken seriously across all DevOps roles and geographies:

“The human skills are finally being recognised as important across all roles and regions. They must be mentioned over and over again.”

— Eveline Oehrlich, DevOps Institute

In the context of DevOps, human skills include:

• Empathy — understanding the pressures faced by developers, operations staff, and business stakeholders
• Communication — translating technical concepts clearly for non-technical audiences and vice versa
• Collaboration — working across organisational silos to remove bottlenecks
• Creativity and problem-solving — finding pragmatic solutions when standard playbooks don’t apply
• Interpersonal skills — building trust with teammates and stakeholders

Oehrlich’s framing of the ideal DevOps professional is worth quoting directly:

“The future of DevOps sits atop a hybrid individual — someone who can work across a variety of functional subject areas, leveraging experts and incorporating key topics of automation and process or framework methodologies to deliver value at speed and quality for the customer.”

— Eveline Oehrlich, DevOps Institute

She adds that the highest-demand, highest-paid DevOps professionals are collaborative, flexible, creative, results-oriented, and generous with their knowledge: “A person who only wants to show how smart they are is not going to be successful in DevOps, but a person who is smart and shares his or her smarts is great.”

Mendiola echoes this on the recruitment side: DevOps professionals cannot rely on a business analyst to act as a communication bridge. They need to speak directly and clearly to both technical colleagues and non-technical stakeholders.

How to Stand Out: The Four E’s and Four Strengths

What, concretely, distinguishes top DevOps candidates from the crowd? Oehrlich points to the four E’s:

1. Experience — a real track record of DevOps work across meaningful projects
2. Expertise — deep, demonstrable skill in at least one or more core areas
3. Exploration — a habit of learning, experimenting, and staying current with evolving practices
4. Execution — the ability to ship, not just plan or advise

IDC’s Mercer offers a complementary list of four strengths that hiring managers value most:

1. Proven experience driving DevOps adoption — not just participating in it, but actively pushing it forward
2. Strong people skills — being a good teammate who raises the capability of those around you, not just yourself
3. Cross-disciplinary leadership — the ability to partner across teams and functions to produce high-impact results
4. Analytical and creative problem-solving — generating practical solutions to novel or ambiguous problems

Specialise, Don’t Just Generalise

One final and important piece of advice from Mendiola: avoid the trap of trying to know a little about everything while excelling at nothing.

“As in any profession, the key to standing out is to specialise.”

— Christian Mendiola, Huxley

This does not mean ignoring breadth — a narrow specialist who cannot collaborate across boundaries will hit a ceiling quickly. It means building genuine depth in one or two areas (say, Kubernetes operations and observability, or CI/CD pipeline design and security automation) while maintaining enough breadth to communicate credibly with adjacent roles.

Practical Next Steps for DevOps Upskilling

If you are ready to act on this guidance, here is a starting framework:

• Audit your current skills against the technical list above. Identify two or three genuine gaps.
• Choose a specialisation direction — for example, platform engineering, SRE, security automation, or observability.
• Build hands-on projects. Lab environments, open-source contributions, and internal tooling improvements all count.
• Pursue recognised certifications where they add signal — for example, the DevOps Institute’s DOFD or DASA DevOps certifications, or cloud-provider DevOps-focused credentials.
• Practice communication deliberately. Write internal documentation, give brown-bag presentations, or contribute to technical blogs.
• Seek out DevOps-immature environments. Building a CI/CD pipeline where none existed is far more impressive on a résumé than maintaining one someone else built.

The DevOps talent gap is real and persistent. Engineers who invest in a balanced combination of technical depth, process knowledge, and human skills will find that the market rewards that investment consistently.

Stephen Thorne, customer reliability engineer at Google, recently spoke at the DevOps Enterprise Summit London on what Site Reliability Engineering (SRE) is and how many organizations are failing to understand its basic premises and benefits . Confounding service level objectives (SLOs) which are focused on early failure detection with service level agreements(SLAs) which often serve as financial compensation for past incidents, not enforcing error budgetsand not dedicating at least 50% effort of SRE teams to improve the systems and tools (instead letting them continue to drown in toil, aka “firefighting” in production) are some keys misunderstandings that Thorne has seen in other organizations.

SLOs are fundamental in detecting issues early, ideally before the effects become visible to customers, added Thorne. A good SLO is aligned with outcomes for the customer (service availability or response time, for example) and thus reflects whether the system (behavior) is meeting user needs. Resource usage (like CPU utilization or network throughput) should be monitored, but not used as an SLO per se. Thorne put it simply as “if the customer is happy, then the SLO is being met”. Typical SLOs at Google include:

• uptime of 99.9% a month (i.e. 43 minutes of downtime a month)
• 99.99% of HTTP requests in a month succeed with a 200 OK
• 50% of HTTP requests returned in under 300ms

SLAs, on the other hand, typically come into play when customers are already dissatisfied with a service, thus failing to proactively improve the system’s reliability. Further, SLAs can lead to the wrong incentives, for example combining an SLA of 2 hours to fix an email issue with an SLA of 1 day to fix a serious production incident might lead to working on one (or more) email problems first although clearly the production issue should be the priority.

Just defining SLOs is not enough, Thorne warned. Error budget policies enable meeting SLOs by setting clear rules for action (not monetary compensation) before a system gets close to an SLO’s threshold. This also minimizes confrontation between ops and dev when systems are failing to meet user needs. “The error budget is the gap between perfect reliability and our SLO” said Thorne. For Google, a typical error budget policy is to disallow launching new features once an application has exhausted its error budget (for example, already over the 43 minutes downtime budget for this month), or dedicating a sprint to corrective actions stemming from previous post-mortem analysis.

Thorne stressed, however, that what works for Google won’t work for every organization: “SRE needs SLOs with consequences that balance an acceptable level of failure with the necessary cost and speed of delivery”. Exact SLOs and policies must be adequate for the organization – not a copy/paste from Google – and focus on continuously improving customers’ experience, not on setting lofty goals or hard punishments that could be counterproductive. Thorne gave the example of one organization struggling to reduce the processing time of a recommendations system. Turned out that users would only see those recommendations when they came back to the site, on average 6 hours later. An adequate SLO was to process all recommendations within 6h, which meant they could save the cost of 3 halftime engineers previously working on the perceived “issue” of slow response time.

Empowering SRE teams to balance workload between every day (often unplanned) ops work and planned work to reduce toil (aka “firefighting”) is the third key to SRE, said Thorne. At Google, this means at least 50% of SRE effort is spent on project work: early consulting on new systems’ architecture to identify resiliency anti-patterns (and avoid more toil later on), improving monitoring, automating repetitive tasks, or coordinating the implementation of postmortem corrective actions.

Thorne further referenced some clear anti-patterns to implementing SRE such as simply rebranding the ops team to SRE team or hiring for SRE engineers without first putting in place the SRE principles and mechanisms (SLOs, error budget policies and balancing workload) for success.

These are 5 key steps to get on the right path to SRE, according to Thorne:

1. define contextual, customer-focused SLOs
2. define sensible error budget policies
3. hire (internally or externally) SREs and empower them via leadership support
4. allow SREs to finetune SLOs and enforce error budget policies
5. assign responsibility for mission-critical systems’ reliability to SRE teams, other systems under the responsibility of the corresponding development team

Google developed and expanded the site reliability engineering discipline internally for some years, before condensing their lessons learned into the SRE book. Thorne mentioned an accompanying SRE workbook will be coming out later this month.
