Tomcat: From a Cluster to a Cloud
summary
Explains how Tomcat moves from multicast clusters to cloud deployments by using the Kubernetes API discovery or DNS membership to find peers, and compares the simpler DNS lookup with the more robust kubernetes qbp ping approach. Shows an actual Kubernetes demo with a counting webapp, an Operator that automates deploys and image updates, and notes the need for liveness probe / readiness check and a CNI network so pods and nodes can communicate.
