DevOps as its name suggests is made from a combination of Development and Operations. From Planning to the Final product, this process is followed by the Developers and Operational team together. There are different phases under the DevOps lifecycle. These are defined as continuous development, continuous testing, continuous integration, continuous deployment, continuous monitoring, feedback, and continuous operations We will briefly explain all the above-mentioned phases below.  Continuous Development:  This is the first phase of the DevOps lifecycle and it involves both planning and coding of the software. This phase decides the vision of the project to understand it completely on a higher level. This phase not only helps to get financial and management level knowledge but also helps to get insights from both Operations and development teams. There is no specific tool of DevOps that is required in this phase but any feasible tool can be used. During the application coding, any SCM (Source Code Manager) tool can be used to store the code like Git, etc. Code versioning is also possible and developers can modify the saved code and can create multiple versions of code. There is a privilege provided to use any type of language for coding according to the projection requirements. After code check-in on the SCM tool, any packaging tool can be used like maven, etc to package the code into an executable format which can then be moved to the next phase.  Continuous Testing:  This phase is used to test the application continuously to detect any bugs or issues at an early stage. Automation testing tools like Selenium, TestNG, etc. are preferred for testing applications rather than manual testing to save time. Jenkins can be used to automate the entire testing phase where the Selenium tool will test the code automatically and TestNG will generate corresponding test reports. The primary focus of the phase is to enhance the quality of code by testing it at an early stage and then integrating it continuously with the existing source code.  Continuous Integration:  In the DevOps lifecycle, this stage act as the heart. This phase involves the integration of new code with the source code, Unit, Integration testing, and packaging of the code to move it to the production server. When developers commit their new code to the source code in SCM tool like Git, then this updated code is built and tested to detect any problem at an early stage. Tools like Jenkins or circle CI can be used for continuous integration. It will detect changes made in the source code in Git and it will get the updated code, test it, and package it into an executable format(.jar) to move it to the next phase.  Continuous Monitoring:  This phase also known as Continuous Control Monitoring (CCM) is a very crucial stage that is used to monitor operational parameters of application usage for the identification of any problem areas or any trend. Tools like Nagios, Splunk, etc can be used for continuous monitoring. Monitoring can be done in the form of documentation or collecting large-scale data from an application while it is under continuous use. This phase helps to maintain service availability and security. Server unavailability issues or memory issues are rectified in this phase.  Continuous Deployment:  This phase as its name suggests helps to deploy the code to the production servers. As the new code is deployed continuously, it is very important to make sure that code consistency is there in all environments for which containerization tools like docker can be used to maintain consistency across development, staging, testing, and production environment. By doing so, there will be no chance of any error or failure in the production environment as these tools replicates the same packages and dependencies from lower to production environments.  Continuous Operations:  We know that in DevOps, continuity is the key factor to automating all the processes from planning to product release. This phase focuses on automating the application or software release and its corresponding regular new updates to the end users that help organizations to release their products to the market without any delay and it also helps the developers to focus more on code development than focussing on release management.  Continuous Feedback:  We know that feedback is very crucial after every software release to make required improvements in the next release. As continuity is key in DevOps to save time and remove manual work, continuous feedback should be placed between the Operations and the Development phase to get continuous feedback from application operations, finding out issues in the current release and releasing a better version in the future based on the feedback.
