What is Continuous Integration & Deployment?

Continuous Integration (CI) is a best-practice where engineers coordinate code into Github, Bitbucket or another version control system every now and then, ideally a few times each day. Every such integration would then be able to be checked by a process which will construct and carry out tests. While this testing isn't always part of CI it is often inferred. One of the key advantages of incorporating consistently is that you can catch issues rapidly and find them without waiting for a large integration phase. As each change presented is normally incremental, pinpointing the particular change that presented the deformity should be possible at a much faster pace. Furthermore, Continuous Deployment and Continuous Delivery allow the application to be deployable anytime or in any event. This permits software development teams to move quickly while keeping excellent standards that can be verified programmatically.

What's the benefit of CI for web developers?

For web developers, Continuous Integration brings cost savings and development benefits. Here we list some advantages of Continuous Integration for any business dealing with code deployment:

- Increased QA - Quality Assurance
- Reducing risk of large scale integration
- Ability to stage and rollback changes
- Ability to deploy changes incrementally
- Analysis and reporting on the code base & code health
- Ability to scale projects to large development teams

Continuous Delivery - A typical scenario

Here is a general life cycle scenario of CD:

- A developer checks latest code in to the repository
- If successful, the build process commences
- Continuous Integration processes are triggered
- Running automated tests (Funcional, Unit tests, etc)
- If the build fails, the check-in is rejected and the team notified
- If the build passes, the code is integrated and seamlessly deployed through the deployment process
