Eight systems for continuous integration and continuous delivery in comparison

table of contents

Developing software is a team matter. Developers often work together and, above all, at the same time on the same code. Continuous integration is the process that ensures that the work of each individual is regularly brought together and that the application always meets the quality requirements. This allows possible conflicts to be identified at an early stage – instead of the application being delivered incorrectly in the worst case.

From a technical point of view, a CI system implements the Continuous Integration (CI) process. A pipeline describes the individual steps that ensure that all changes to the software that are integrated are compatible with one another and are of the desired quality. Common steps include compiling the code, running the unit tests, or static code analyzes. Such a pipeline begins with the transfer of new code to the version control system. At the end there is the fully built and potentially deliverable application.

The concept of continuous delivery goes even further. The term itself appeared eleven years ago in the title of the book “Continuous Delivery: Reliable Software Releases Through Build, Test, and Deployment Automation” by Jez Humble and David Farley. The idea behind this is to bring software into production and make it available on a regular basis. The main reason why companies want to regularly distribute software productively is described by the catchphrase time-to-market: It’s about minimizing the time it takes to implement a feature and use it productively. It stands to reason that a team that feeds into the production environment several times a week also needs less than a week to bring an implemented feature into production.
