CI/CD stands for Continuous Integration (CI) and Continuous Deployment or Continuous Delivery (CD). Continuous Integration encompasses the automated testing and merging of new code with existing software, with development teams using automation tools (e.g. CircleCI, Jenkins) to automatically test and merge new code as seamlessly as possible. Continuous Delivery, on the other hand, is a natural follow-up to CI. Instead of preparing one big release a few times in the year, a new code is available for on-demand release, even a few times a day. It is not only much easier to detect and fix bugs in small batches, but also much wiser as the software becomes more bug-resistant. Finally, Continuous Deployment means that every change in the code should be deployed constantly and automatically in production. In an ideal scenario, this should be done without any human intervention.
