What happens if Consul server goes down?

If the failed server is recoverable, the best option is to bring it back online and have it rejoin the cluster with the same IP address. This will return the cluster to a fully healthy state.

What causes a server outage?

Servers typically run 24/7, and as with any machine, wear and tear inevitably leads to shutdowns. Aside from the effects of continued use, accidents and calamities can also cause hardware breakage. One or any combination of these can even be so severe as to cause the complete destruction of server infrastructure.

The consul agent is responsible for health-checking the services on the node as the health-check of the node itself. It is not responsible for service discovery or maintaining key/value data. Consul servers are where data is stored and replicated.

Raft is a consensus algorithm that is based on Paxos. Compared to Paxos, Raft is designed to have fewer states and a simpler, more understandable algorithm.

How do you check the health of Microservices?

To add readiness or liveness health checks to your microservice, create a class in your application code that implements the HealthCheck interface and add either the @Liveness or @Readiness annotation to it. These annotations specify the conditions that determine whether the health check passes or fails.
