When you next login to your Host Account you will see a new tab called Dashboard, as shown below It improves overall resilience of the system by isolating the failing services and stopping the cascading effect of failures. So here comes the need of designing the system for resiliency. Hystrix is a library that helps you control the interactions between these distributed services by adding latency tolerance and fault tolerance logic. Protecting against failures in the entire dependency client execution, not just in the network traffic.
