CI stands for “Continuous Integration” and is a DevOps process in which developers regularly merge code changes in a central repository.
Automated steps such as tests are designed to detect errors at an early stage and improve software quality. This process forms the basis for Continuous Delivery (CD), in which new software versions are made available at certain intervals or when certain quality criteria are met. The benefits of continuous integration include scalability, improved feedback loops, optimized communication and increased efficiency.
Challenges during implementation include the migration of projects without CI, integration into existing teams and dealing with new technologies.
