What is DevOps?

DevOps is a portmanteau of the words: Developers and Operations. It primarily refers to practices employed in the software development process which enhance collaboration and communication and automated software delivery process. The stages of development, testing and deployment occur frequently and reliably in this process. The main purpose of DevOps or this framework is to make the working of the development and operations team cohesive and smooth by increasing knowledge sharing.

 The principles of DevOps

DevOps is considered as a skill-set, a role in SDLC, a framework for development and operations or as a job description. There are many conflicting definitions of DevOps and all should be united to understand the bigger role DevOps plays for an organization. Once the DevOps environment is established properly, it could lead to a lot of growth opportunity for the organizations.

The best practices of DevOps include:

  1. Seamless integration of the changes.

  3. Transparency between the different teams
  4. Flexible approach to ensure the teams adapt to changes or any exceptional circumstances.
  5. Open culture in the organization with a focus on teamwork, collaboration, and good communication.
  6. The automation of software should be carried out in stages :
  • Continuous Integration: The code is integrated with a larger piece of code and tested.
  • Continuous Delivery: The development team works in sprints and churns out an incremental release.
  • Continuous Deployment: If the code passes all the phases of testing, it is deployed to production
  • Continuous Monitoring: The application is monitored for any bugs or defects and the issues are resolved.
