Deployment is a huge challenge. To overcome this, we can introduce CI. In this process, we need to set up a CI server. With the introduction of CI, the entire process is now automated. As soon as the code is checked in by any team member, using version control TFS or Git in our case, the CI process kicks into action. It ensures that the new code is built and unit tests are run along with the integration test. In both scenarios, a successful build or otherwise, the team is alerted of the outcome. This enables the team to respond quickly to issues.
Next, we have continuous deployment. Here, we introduce various environments, namely a development environment, a staging environment, a Q/A environment, and so on. Now, as soon as the code is checked-in by any team member, continuous integration kicks into action. It invokes unit/integration test suites, builds the system, and pushes it out to the various environments we have set up. In this way, the turnaround time of the development team to provide a suitable build for Q/A is reduced.
