Key Takeaways

  • It was formed by joining 2 words: “Development” and “Operations”
  • DevOps is a closed environment that helps cross reference business tasks

Why DevOps Is Required?

When DevOps was not introduced, at that time the development team and operations team worked in complete isolation. Testing and deployment both were secluded activities done after design. Hence, they take more time than the actual build cycles.

  • Manual code deployment tends to cause human errors in the production environment.
  • Coding & OP team have their unique timelines and are not in sync making further delays.
  • There is an ask to increase the rate of software productivity by business stakeholders.

Phases of DevOps

  • Plan: It is the first stage in the DevOps lifecycle. The business owners and the development team discuss the project goals and create a plan.
  • Code: Programmers then code the application to achieve the requirements. Tools like git are used to store the application.
  • Build: Tools like Maven and Gradel gather the code from different repositories and combine them to build the application.
  • Test: This phase includes continuous testing manual or automated to ensure optimization.
  • Integrate: Once testing is completed new features are integrated automatically to the code base.
  • Deploy: Application is packaged after release and deployed from the development server to production server.
  • Operate: Once the application is deployed, the operation team configures the servers and arranges them with the required resources.
  • Monitor: Allows IT organizations to identify specific issues of specific release and to understand and take the feedback of end users.

Devops Tools

  • Plan: In planning the tool that provides repositories for managing and storing various versions of code. Example; Jira Software and git which helps in project management.
  • Code: These tools help in creation of design tools. Example Github, GitLab, etc.
  • Build: Fetches the source code from repositories and packages them into executable applications. Example: Gradel, Maven, etc.
  • Test: these tools help in continuous testing to ensure optimal code quality. Example: TestNG, Selenium, JUnit, etc.
  • Deploy and Operate: Helps to manage, coordinate, schedule, and automate application release production. Sample tools include Chef, Puppet, Docker, etc.
  • Monitor: provides continuous monitoring of release products. Tools include Nagios, Wireshark, Splunk, etc.
  • Integrate: it is the heart of DevOps which automates the integration of all the stages. Sample tools include Jenkins.

Key Components of DevOps

  • Continuous Integration- Continuous Integration is a crucial step of the Agile. Usually developers work on features or stories within a sprint and commit their modification GIT.
  • Continuous Testing- Continuous testing is the process of executing automated tests as part of the software delivery in order to obtain the response on the business issues associated with a software release as fast as possible.
  • Continuous Delivery- CD is an extension of CI which supports getting the features which the developers are developing for the customer as soon as possible. During this process, it goes through various stages of Quality Assurance, Staging and then for deployment to the production system.
  • Continuous Monitoring- As the application is developed, we monitor its performance. Monitoring is crucial as it helps to discover the issues which might not have been identified on an early stage.
