etcd vs consul vs ???

	- What do Etcd, Consul, and Zookeeper do?
	- Service Registration:
	- Host, port number, and sometimes authentication credentials, protocols, versions
	numbers, and/or environment details.
	- Service Discovery:
	- Ability for client application to query the central registry to learn of service location.
	- Consistent and durable general-purpose K/V store across distributed system.
	- Some solutions support this better than others.
	- Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
	- Centralized locking can be based on this K/V store.
