In this article, we will cover the basics of CI/CD, what actually it is and how it is implemented in software testing. What is continuous integration? In simple terms, development teams can integrate their code into a shared repository. This helps in maintaining code quality and identifying potential issues with the local version of the code at an early stage. What is continuous delivery? Everything that is being continuously merged by the development team, is continuously deployed to the live environment. Continuous delivery is often coined as ‘Continuous Deployment’ as well.

Now how do we differentiate between the three categories as a user? Will cover the details below. Infrastructure as a Service(IaaS) Service provider provides you the hardware User gets some control over the hardware, can customise operating system, storage and VMs. Ensuring service is up and running is shared responsibility While cloud provider makes sure that the hardware is functioning correctly, user needs to make sure ...
