Battle of the Circuit Breakers: Istio vs Hystrix/Resilience4J


Kubernetes in general, and Istio in particular, have changed a lot the way we look at Ops-related constraints: monitoring, load-balancing, health checks, etc. Before those products became available, there were already available solutions to handle those constraints. Among them are different libraries e.g. Hystrix and Resilience4J in the Java ecosystem. In particular, they both provide an implementation of the Circuit Breaker pattern, which prevents a network or service failure from cascading to other services. But now Istio also provides the same capability. In this talk, we will have a look at how Istio and one among Hystrix/Resilience4J implement the Circuit Breaker pattern, and what pros/cons each of them has. Bonus, you'll be able to choose what library we will focus for the demo. After this talk, you’ll be able to decide which one is the best fit in your context.
