In our application, deployment is a huge challenge. To resolve this, we introduce Continuous Integration (CI). In this process, we need to set up a CI server. With the introduction of CI, the entire process is 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 either scenarios of a successful build or otherwise, the team is alerted to the outcome. This enables the team to quickly respond to the issue.
Next we move to continuous deployment. Here we introduce various environments, namely a development environment, staging environment, QA environment, and so on. Now, as soon as the code is checked in by any team member, CI kicks into action. It invokes the unit/integration test suits, builds the system, and pushes it out to the various environments we have set up. This way, the turnaround time of the development team to provide a suitable build for QA is reduced to minimal.
