Santa Claus does not exist. Nor do 100% reliable services. Both facts are hard to accept, but just a matter of reality. The good news: There are fault tolerance frameworks that can soften the bad consequences of delayed response time, unavailability and other temporary issues. And the even better news: They are relatively easy to apply to existing applications - if you know what you are doing.

In this session, we will demonstrate how Java applications can be amended to be fault tolerant - in classical environments, with Kubernetes and with Istio Service Mesh.
