  • 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.
