DevOps is a trendy way to fill the gap between two different streams (developers and operators) that work towards the same goal. It is a modern software development and infrastructure management process which helps the organization to boost their efficiency and velocity of work. DevOps has become a more popular and widely used technology. Let’s discuss What exactly is DevOps and What is the lifecycle of DevOps in this blog.
What is DevOps?
The term DevOps indicates Dev+Ops which suggests development(dev) and operations(ops). The combination of both the Software Development team and IT operations team to coordinate and collaborate to optimize both the productivity of developers and therefore the reliability of operations. To provide more value to the customers, organizations adopt this DevOps culture along with various practices and tools. The tools used are Git, Jenkins, Docker, Ansible, Puppet, etc. DevOps Certification Training includes all the concepts of DevOps including DevOps tools and various aspects of software development which will be helpful for you to become a DevOps Engineer.
How DevOps Works?
To explain it more elaborately, In any software company, they need a software development team in which they are two sorts of employers – developers, and operators. The role of developers is to build a code and operators are to test the code. Any code is developed by a developer and it’ll be sent to the operator to check it. Then if the developer found any bugs then he gives the feedback and reverts it back to the developer. And therefore the developer needs to recheck it and should send the code again to the operator. But the problem comes when the developer runs the code in his system it works properly and when it is sent to the operator he finds bugs. This problem affects the time and productivity of the work. And the idea of the solution is to adopt a structural change that makes the developers and operators work together which is termed DevOps.
DevOps Life Cycle
DevOps lifecycle has different stages such as Continuous Development, Continuous Integration, Continuous Testing, Continuous Deployment, Continuous Monitoring, and Continuous feedback. Using these phases of DevOps, an organization can achieve its goals and reach the market in time. Let’s understand these phases in detail. Read on!!
In the phase of continuous development, all the team members work on planning the idea of project development and they start working on the entire coding part for the software program. In this stage, the team members also spare time to picture the end result of the program.
Then comes the next stage which is Continuous Integration. This is a crucial phase of the DevOps life cycle. It is a software development approach that requires developers to submit source process improvements more often. Here, the code needs to be compiled and the primary errors are detected. Tools like Jenkins are much more useful in the continuous integration process. Integration and packaging are done in this stage. And the updates or changes required in the code are modified and sent to the next stage.
The next phase of Continuous Testing. Testing tools such as Selenium, TestNG are used in this phase for continuous testing of the code and finding the errors. Continuous testing lowers the cost of testing while also assisting software developers in balancing performance and effectiveness. It also reduces test inefficiencies with simulated applications and makes it easier to create a standardized testing environment that can be deployed, distributed, and upgraded as processes evolve.
Continuous Monitoring is a step of the DevOps strategy that incorporates all functional areas, wherein essential data about the software’s activity is captured and thoroughly analyzed to derive insights and pinpoint issue areas. Continuous monitoring provides crucial initial input for lowering the number of mistakes and directing operations in the proper path.
Continuous feedback is a critical process in software successful development. An application will be fully completed without any errors because of continuous feedback. Continuous feedback among processes and the production of the present software application helps us to review our project by assessing the outcomes of the software’s activities, software development is constantly enhanced and also helps to make it even better.
In this Continuous Deployment phase, The deployment method is carried out in such a way that any changes to the code do not affect the operational outcomes. Here, New code is continually delivered, and configuration management solutions are critical for completing tasks often and rapidly. Containerization software is also crucial during this process. They help in the integrity of an application’s testing, development, and deployment ecosystems. And they make sure that there is no risk of mistakes or failure in the production environment. Chef, Puppet, Ansible, and SaltStack are some of the most common tools used in this phase.
