DevOps Vs DevSecOps Vs SRE DevOps is a mindset which enables organization to deliver changes efficiently and cost effectivly. Its a blend of Developers and Operations which help to reduce test enviroment setup issue which causes unwanted delays. DevSecOps is the enriched Devops blend with pinch of security aspects. It enables developers to consider the required security/compliance aspect and introduce them in initial phases to avoid challenges and issues which we face after testing. It helps in reducing the duplication

Continue with file delete ops.

We have following Network adaptorin Virtual Box 1.Not Attached-In this mode,VirtualBox reports to the guest that a network card is present,but there is no connection. 2.NAT(Network Address Translation)-It’s a way to map multiple local private addresses to a public one before transferring the information 3.NAT Network-It is type of internal network that allows outbound connections. 4.Bridge networking-A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. This function is

It is a software to run or manage the multiple virtual machines in a computer system. It is a methodology to use resources over net. Cost is Higher in cloud than Hypervisor.

Hypervisor-It is a software to run and manage no of virtual machines in the system It is image based. It relies on single peripheral device. The workload is stateful. Cost is very low as compared to cloud. Cloud-It is a methodology which is used to access resources over internet It is template based. It relies on multiple machines so it is helpful in disaster recovery. The workload is stateless. Cost is higher.

EPEL(Extra Package for Enterprise Linux) is a special intrest group from the Ferdora group that provides some additional packages for Redhat family i.e.Ubuntu,CentoOS etc. For access EPEL user should install EPEL repository yum install epel-release -y For refresh the epel repo yum repolist Install packages from epel repo yum install pkg1

We have following Network Adaptor Mode in Virtual Box Not Attached NAT NAT Network Bridged Adapter Internal Network Host-Only Adapter Generic Driver Not attached. In this mode, VirtualBox reports to the guest that a network card is present, but that there is no connection. This is as if no Ethernet cable was plugged into the card. Using this mode, it is possible to pull the virtual Ethernet cable and disrupt the connection, which can be useful to inform a guest

Hypervisor Cloud Hypervisor is a technology which used for create virtualization Cloud is a methodology which ussed to access resources over internet Create multiple simulated environments from 1 physical hardware system Pool and automate virtual resources for on-demand use Deliver packaged resources to specific users for a specific purpose Deliver variable resources to groups of users for a variety of purposes It is based on Image based It is on Template Based It is low scalable and support scale up

EPEL  is a special interest group (SIG) from the Fedora Project that provides a set of additional packages for RHEL (and CentOS, and others)  from the Fedora sources. It creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS, Scientific Linux (SL), Oracle Linux (OL), AlmaLinux (AL) and Rocky Linux (RL). For access EPEL user should install EPEL repository, to enable EPEL repository Open a

What is DevOps in simple terms? DevOps is a set of practical methods that shorten the time from submission to deployment of system changes to the production environment under the premise of ensuring high quality. DevOps is a combination of two functions that are typically treated separately: development and operations. That definition of DevOps is the Standardized development methodology, clear communication, and documented processes supported by a standards-based, proven middleware platform to improve application development and management cycles, bring agility,

What is DevOps in simple terms?Ans: devops is a combination of all the teams such as development, testing, architecture where all work on common goal or to solve a problem and reduce the time of delivery and to maintain the software quality What exactly do DevOps do?Ans: reduces the time of delivery and improves the quality of the software product by automating the processes. it combines all the teams like development, testing, architecture to work on the goal or problem,

DevOps is a union of development and operations whereas DevSecOps is integration of security in DevOps framework. It ensures the secure workflow of DevOps by selecting the right security tools and parameters. DevSecOps and DevOps, both play a significant role in an environment where software upgrades are usually executed several times daily and obsolete security models can’t sustain it. Where DevOps focuses only on effective deployment of upgrades, DevSecOps address the security concerns along with deployment. The Devops process: Continuous integration (CI) – merges code changes to ensure the most recent version is available to developers

DevSecOps basically stands for Development, Security and Operations and an approach to automate the project by adding the security into it.

DevSecOps stands for development,security and operations.Its an approach to automate the process and security for the the software throughout the entire lifecycle

DevOps Team will reduce the communication gap between the dev and operation team for faster release of application or product or project to the client. Whereas SRE Team will comprehensively get involved into solving the system engineering process by ensuring reliability and stability and will deal with the activities like production failures, infrastructure issues, monitoring.

The main difference between these two is DevOps team will reduce communication between development and operation team for faster application release whereas SRE team will get involved after deploying the application in production environment for system reliability,maintainence and for support related activities
