Zero-downtime Java Enterprise Applications With Kubernetes

The software world moves faster than ever. In order to stay competitive, new software versions need to be rolled out as soon as possible, without disrupting active users. Many enterprises have moved their workloads to Kubernetes, which has been built with production-readiness in mind. However, in order to achieve real zero-downtime with Kubernetes, without breaking or loosing a single in-flight request, we need to take a few more steps.
