Different Lifecycle Stages of DevOps.

Now, let’s discuss the various stages within the DevOps life cycle that contributes to the consistent software development life cycle (SDLC):

• Continuous Development
• Continuous Integration
• Continuous Testing
• Continuous Monitoring
• Virtualization, and Containerization

DevOps training online will help you to learn DevOps basics and provide depth knowledge of various DevOps tools such as Git, Ansible, Docker, Puppet, Jenkins, Chef, Nagios, and Kubernetes. These stages are basically the aspects of achieving the DevOps goal.

Continuous Development

In the Waterfall model, our software product gets broken into multiple pieces or sub-parts for making the development cycles shorter, but in this stage of DevOps, the software is getting developed continuously.

Tools used: As we code and build in this stage, we can use GIT to maintain different versions of the code. To build/package the code into an executable file, we can use a reliable tool, namely, Maven.

Continuous Integration

In this stage, if our code is supporting new functionality, it is integrated with the existing code continuously. As the continuous development keeps on, the existing code must be integrated with the latest one ‘continuously,’ and the changed code should ensure that there are no errors within the current environment for it to work smoothly.

Tools used: Jenkins is the tool that is used for continuous integration. Here, we can pull the latest code from the GIT repository, of which we can produce the build and deploy it on the test or the production server.

Continuous Testing

In the continuous testing stage, our developed software is getting tested continuously to detect bugs using several automation tools.

Tools used: For the QA/Testing purpose, we will use many automated tools, and the tool used widely for automation testing is Selenium as it lets QAs test the codes in parallel to make sure that there is no error, incompetencies, or flaws in the software.

Continuous Monitoring

It is a very crucial part of the DevOps life cycle where it provides important information that helps us ensure service uptime and optimal performance. The operations team gets results from reliable monitoring tools to detect and fix the bugs/flaws in the application.

Tools used: Several tools like Nagios, Splunk, ELK Stack, and Sensu are used for monitoring the application. They help us monitor our applications and servers closely to check their health and whether they are operating actively. Any major issue detected by these tools is forwarded to the development team to fix in the continuous development phase.
