Hystrix (CloudMonk.io)

Hystrix

Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services, and 3rd party libraries, stop cascading failure, and enable resilience in complex distributed systems where failure is inevitable. Developed by Netflix, Hystrix provides a set of tools to control the interactions between these distributed services by adding latency tolerance and fault tolerance logic, helping systems to stay responsive in the face of failures. Key features include the circuit breaker pattern, which prevents a network or service failure from cascading to other services; fallback methods for providing a default response when operations fail; and real-time metrics and monitoring. Although Netflix has moved on to other solutions and put Hystrix into maintenance mode, its concepts and methodologies continue to influence modern microservices architectures and resilience patterns in distributed systems.
