One of the most important things when building microservices for the enterprise mission critical systems
is high reliability. Even if a new deployed service has a bug,
it is required that the other services should not be affected by this bad service.
This session will provide how to build such a robust system with MicroProfile functions such as
Fault Tolerance, Metrics, and OpenTracing.
Although there are a lot of tuning knobs in Fault Tolerance (timeout, circuitbreaker, retry, fallback, and so on),
it is very difficult to find the best values for each parameter of each microservice.
This session will provide the demonstration to show how to tune these parameters in cooperate with Istio,
and other various tools, such as Grafana and Kiali, to monitor microservices,
and the attendees will learn how to find the best parameter values.
