Case study

With CI set up, the next thing our two pilot teams at Tailwind Gears need to do is automate the deployment and release processes of the software.

The first team runs some web applications that are still hosted on-premises. Instead of automating the on-premises deployment, the team moves the applications to a hosted Kubernetes service in the cloud. The cluster instances, network, and other cloud resources have already been set up by the IT department during the last sprints.
