When you’re testing your enterprise application in a Kubernetes environment, the turnaround for changing, re-packaging, and re-deploying your application can become quite high.
Telepresence aims to mitigate this, by proxying a locally running process into our Kubernetes cluster, as if the local process were part of the cluster.
If we combine that approach with a hot-redeploy tool such as WAD we can vastly improve our development productivity.

The idea behind bulkheads is to split applications into several execution units that isolate functionality.
In enterprise Java applications this typically means to define multiple thread pools.

You can make the Prometheus configuration aware of the Kubernetes environment your applications are running in.
I’ve described how to do that manually, in a previous blog post.
Prometheus Operator is an extension to Kubernetes that manages Prometheus monitoring instances in a more automated and effective way.
