Hosted Continuous Integration is a hot area but also a very competitive domain. While some choose to have it hosted in the cloud others like to have more corporate autonomy with using such tools as Jenkins and TeamCity. Continuous Integration is an agile work flow practice that involves developers to integrate on code, in shared repositories, and utilize automated tests to verify for build quality, in order to allow teams to check for issues, early and often, on a daily basis. A step further in the Continuous Integration process is Continuous Delivery. Continuous Delivery being the hardest bit to fully achieve on a large complex architecture and may even prove to be foolhardy. Although, CI has been around for years, it really boils down to team dynamics and whether one really has the time to manually setup and monitor builds in comparison to a hosted option. In some corporate environments, teams may even have a dedicated team member for build and configuration management. The following is a list of a few hosted Continuous Integration providers and the different use cases that they provide for an agile software engineering process.
