DevOps Life Cycle Phases: Everything You Need to Know
The phrase DevOps is a combination of two terms: development and operations. DevOps is a product development methodology that enables outstanding programming quality to be scaled quickly and reliably. Without knowing the steps of the DevOps lifecycle, learning DevOps is incomplete. The DevOps lifecycle is divided into seven stages, as shown below:
This step involves the product’s arrangement and coding. During the planning stage, the venture’s vision is decided. In addition, the developers begin executing the application’s code. There are no DevOps tools required for planning, however, there are several tools for maintaining the code.
This is the most important step in the DevOps lifecycle. It is a method of product enhancement in which developers are required to submit modifications to the source code more often. This might be done daily or every week. Then each submission is created, allowing for early detection of errors if they are present. Building regulation encompasses not just complex assembling, but also unit testing, combination testing, code auditing, and bundling.
The code that adds new functionality is regularly merged with the existing code. This allows for the continuing growth of programming. To reflect changes to end-users, the updated code should be regularly integrated and readily with frameworks.
Jenkins is a commonly used tool in this stage. Jenkins takes the refreshed code and prepares a form of that code, which is an executable record as a war or container, whenever the Git repository is adjusted. This form is then forwarded to the testing server.
This is the stage in which the generated programme is thoroughly tested for defects. Automation testing technologies like TestNG, JUnit, Selenium, and others are used for continuous testing. These technologies enable QAs to properly test different code bases in parallel to guarantee that the functionality is flawless. Docker Containers may be used to simulate the test environment at this phase.
The automation testing is handled using Selenium, and the reports are generated by TestNG. With the aid of a Continuous Integration platform called Jenkins, the entire testing procedure may be automated.
Instead of doing the tests manually, automation testing saves a lot of time and work. Aside from that, the ability to generate reports is a huge benefit. The work of assessing failed test cases in a test suite becomes easier. We can also schedule the test cases to run at predetermined periods. The code is continually merged with the current code when it has been tested.
Monitoring is a part of the DevOps process that includes all operational aspects, where crucial information about the software’s use is captured and carefully analysed to uncover trends and pinpoint issue areas. Typically, monitoring is included in the software application’s operating features.
When it is in a continuous usage position, it may create large-scale data on the application parameters in the form of documentation files. In this phase, system issues such as server not accessible, low memory, and so on are rectified. It ensures the service’s security and availability.
By assessing the outcomes of the software’s activities, the application development is constantly enhanced. This is accomplished by establishing a key phase of continual feedback between operations and the development of the present software application’s future iteration.
Continuity is critical in DevOps because it eliminates the stages that are required to remove a software programme from development, use it to diagnose flaws, and then produce a better version. It eliminates the app’s potential for efficiency and reduces the number of interested customers.
The code is pushed to the production servers at this phase. It is also critical to check that the code is appropriately implemented across all servers.
New code is regularly delivered, and configuration management solutions are critical for completing tasks often and rapidly. Chef, Puppet, Ansible, and SaltStack are some of the most common tools used in this phase.
During the deployment phase, containerization technologies are also critical. Popular technologies for this purpose include Vagrant and Docker. These tools aid in the generation of consistency throughout the development, staging, and testing environments. They also aid in the gentle scaling up and down of instances.
Containerization technologies aid in the consistency of an application’s testing, development, and deployment environments. Because they package and reproduce the same dependencies and packages used in the testing, development, and staging environments, there is no risk of mistakes or failure in the production environment. It allows the programme to operate on a variety of systems.
All DevOps operations are built on a foundation of consistency and total automation of the release process, allowing the company to continually reduce its overall time to market.
Continuity is a significant aspect in DevOps in reducing phases that frequently distract development, take longer to uncover errors and result in a better version of the product after several months, as evidenced by the debate. We can improve the efficiency of any software product and raise the total number of interested clients using DevOps.
