What is Consul used for?

Quick Answer
Service discovery, health checking, a distributed KV store, and (with Connect) a service mesh.

Services register with Consul and discover each other via DNS or HTTP, with health checks removing unhealthy instances from results. The KV store holds dynamic config, and Consul Connect adds mTLS service mesh. It's a multi-tool for connectivity in dynamic infrastructure.
