As I have already mentioned, Hystrix is not only a simple tool implementing a circuit breaker pattern. It is a solution that deals with latency and fault tolerance in distributed systems. One interesting feature provided by Hystrix is the ability to expose the most important metrics related to interservice communication and display them using a UI dashboard. This function is available for clients wrapped with the Hystrix command.
In some previous samples, we have analyzed only a part of our system to simulate a delay in communication between customer-service
and account-service
. That's a really good approach when testing advanced load balancing algorithms or different circuit breaker configuration settings, but now we will go back to analyzing the whole of our sample system setup as a set of standalone Spring Boot applications. This allows us to observe how Spring Cloud, in conjunction with Netflix OSS tools, helps us to monitor and react to latency...
