What is DevOps? 

DevOps is a collection of practices that bring together software development and IT operations. Its goal is to shorten the systems development life cycle and consistently provide high-quality software. DevOps is complementary Agile software development; several DevOps perspectives came from the Agile methodology. 

What is the history of DevOps? 

Andrew Clay and Patrick Debois had a talk in 2008 that led to the creation of the DevOps concept. They were concerned about Agile’s shortcomings and set out to find a better alternative. The concept gained acceptance over time, and by the time the DevOps Days conference in Belgium in 2009 rolled around, it had become quite a buzzword. 

In March of 2011, Cameron Haight of Gartner re-presented his predictions for the trajectory of DevOps over the subsequent few years. The positive overlook on its impact on the industry because more attention for the DevOps movement, and it wasn’t long before enterprises of all sizes were getting down to adopt these new practices. DevOps had officially caught on because of the next big thing since Agile for the IT industry. 

How is DevOps different from traditional IT? 

To understand the changes DevOps brings, let’s compare the Traditional software waterfall approach to DevOps. 

Traditional IT DevOps 
The Development team starts testing after placing an order for new servers. In order to implement the infrastructure, the Operations team works on a lot of paperwork, which is standard in businesses. Following the purchase of new servers, the Development and Operations teams collaborate on the paperwork required to set up the new servers. As result, the infrastructure demand becomes more visible. 
Because no inputs from developers with deep knowledge of the application are available, projections about failover, redundancy, data center locations, and storage requirements are skewed. Projections about failover, redundancy, disaster recovery, data center locations, and storage requirements are pretty accurate due to the inputs from the developers. 
The Development team’s progress is unknown to the Operations team. According to their understanding, the operations team develops a monitoring plan. The Operations staff is fully aware of the progress made by the developers in DevOps. The operations team collaborates with developers to create a monitoring plan that meets both IT and business requirements. They also make use of sophisticated Application Performance Monitoring (APM) software. 
The load testing crashes the program before it goes online. The release has been postponed. The load testing makes the program a little slow before it goes live. The bottlenecks are rapidly fixed by the development team. On schedule, the application is released. 

What are the benefits of DevOps? 

DevOps has a plethora of advantages. From a technical standpoint, DevOps has various advantages. Some of the advantages of DevOps for businesses are given below. 

  • Dynamic iteration cycle 
  • Automating of processes 
  • Technical scalability 
  • Efficient documentation with proper code synchronization 
  • Constant integration and delivery 
  • Easy to spot errors 
  • Convenient security maintenance 
  • Transparency in the organizational structure 
  • Stable operating atmosphere 

What is DevOps Work Flow? 

A DevOps workflow is a visual representation of the order in which input is supplied. It also specifies which action is carried out and what output is created for an operations procedure. The ability to separate and arrange the jobs that are most frequently requested by users is provided by DevOps workflow.

  • Continuous development:  The iterative process of producing software to be provided to clients is referred to as continuous development. Continuous integration, continuous testing, continuous delivery, and continuous deployment are all part of the process.
  • Continuous integration: Continuous integration (CI) is a software development technique that is frequently used in the DevOps process flow. Developers merge their code changes into a shared repository on a regular basis, and the updates are tested automatically. Continuous integration ensures that developers always have access to the most up-to-date and approved code. CI helps avoid costly development delays by allowing several developers to confidently work on the same source code, rather than waiting until release day to integrate various pieces of code all at once.
  • Continuous testing: Continuous testing is a verification technique that helps developers to confirm that their code works as expected in a real-world setting. Testing can reveal flaws and specific areas of the product that need to be fixed or improved, and these issues can be pushed back to the development stage for further development.
  • Continuous monitoring and feedback: Throughout the development process, your team should have protocols in place for ongoing product and system monitoring and feedback.. To give constant input, the majority of the monitoring process should be automated. This method enables IT operations to detect problems and alert developers in real time. Continuous feedback promotes increased security and system reliability, as well as quicker reactions when problems develop.
  • Continuous delivery: Continuous delivery (CD) is the obvious next step after continuous integration (CI). Changes to the code are created, tested, and packaged automatically before being released into production. The objective is to provide users with updates in a timely and consistent manner. CD does this by automating the release process (building on CI’s automated testing) so that fresh builds may be released with a single click.
  • Continuous deployment: Continuous deployment may be a better choice than CD for a seasoned DevOps team. Continuous deployment is a completely automated form of CD that does not require any human (i.e. manual) interaction. Every verified update is automatically published to users via a continuous deployment procedure. This method eliminates the requirement for set release dates and shortens the feedback loop. Developers can obtain user input faster and solve issues with more agility and accuracy with smaller, more frequent releases.

What is the Roles, Responsibilities, and Skills of a DevOps Engineer? 

DevOps teams function go-betweens for IT operations and engineering. While DevOps teams rarely engage with external customers, they maintain a “customer first” approach to confirm that both internal and external customers receive high-quality service and goods. To grow cloud programs, plan and style workflow processes, develop automation procedures, deploy updates, and so on, DevOps teams collaborate with other teams. 

A DevOps engineer collaborates with a variety of teams and departments to develop and implement software solutions. DevOps experts have experienced IT professionals who work with software developers, quality assurance specialists, and IT personnel to manage code releases. 

DevOps engineers must be able to multitask, be flexible, and deal with a variety of situations at the same time. A DevOps engineer’s responsibilities are as follows: 

  • Documentation: Writes specifications and documentation for server-side features. 
  • Systems analysis: Analyzes current technology and develops strategies for enhancing and expanding it. The DevOps engineer provides fast analytic support. 
  • Development: IT solutions are developed, coded, built, installed, configured, and maintained. 
  • Project planning: Participates in project planning meetings to offer their understanding of system options, risk, impact, and cost-benefit analysis. DevOps engineers also discuss operational needs and development projections. 
  • Testing: Tests code, procedures, and deployments to find ways to make them more efficient and error-free. 
  • Deployment: Automatically deploys updates and fixes into the production environment using configuration management software. 
  • Maintenance and troubleshooting: Maintains the production environment by performing routine application maintenance. Creates maintenance specifications and procedures. 
  • Performance management: Performs gap analysis, identifies alternate solutions, and assists with revisions to recommend performance improvements. 
  • Management: The DevOps engineer may also be in charge of supervising a team of DevOps engineers, depending on the size of the company. 

How much does DevOps engineer make/salary? 

Despite being a contentious moniker, LinkedIn reports that DevOps engineer is the most sought-after position. If you have this job title, don’t expect to be unemployed for long. However, you should still do your homework ahead of time to ensure that you are fairly compensated for your skills. 

Although DevOps is in increasing demand, businesses want individuals to have the necessary skill sets. Furthermore, the better the experience, the bigger the wage. According to PayScale, the average DevOps income in India is Rs 674,202 per year, consisting of bonuses and profit-sharing. 

What is the future of DevOps? 

DevOps teams will continue to have significantly more influence in the data strategy process in 2021, resulting in a bigger increase in workload mobility, which will be accompanied by a growth in cloud data management strategies. 

DevOps workers will have more time to promote efficient innovations as the industry continues to migrate toward software management utilizing standardized frameworks. These professionals will also have more time to focus on the problems they confront when it comes to managing huge clusters of complicated applications that span many technology stacks.
