HashiCorp Consul

Consul RPC Mechanism

HashiCorp Consul is a distributed, highly-available service which provides service discovery with corresponding health checks, a distributed key/value store, and a service mesh solution, which can run on a variety of platforms and environments. It is designed so that every node which provides services (things to be registered in service discovery, or participate in the service mesh) runs a Consul agent, which acts as a sort of intermediary: providing an easy interface for registering services, running local health checks for both services and the node upon which it is running, and acting as a control plane for service mesh components running on that local node, amongst other things.
