 > [!NOTE]
 > Netflix Hystrix is widely used in existing Spring Cloud apps, but it is no longer in active development. If you are developing new project, you can consider [resilience4j](https://github.com/resilience4j/resilience4j) instead. Circuit Breaker Dashboard for resilience4j depends on micrometer, which is currently not supported for Azure Spring Cloud, so it will not be covered by this tutorial.
