    What is Consul?

    Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.

    What is Serf?

    Serf is a service discovery and orchestration tool that is decentralized, highly available, and fault tolerant. Serf runs on every major platform: Linux, Mac OS X, and Windows. It is extremely lightweight: it uses 5 to 10 MB of resident memory and primarily communicates using infrequent UDP messages.

    What is Zookeeper?

    A centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications.

      What are some alternatives to Consul, Serf, and Zookeeper?
      etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.
      SkyDNS is a distributed service for announcement and discovery of services. It leverages Raft for high-availability and consensus, and utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights (more info here:
      Map services to arbitrary URLs in a single, declarative YAML file. Configure routes with CORS support, circuit breakers, timeouts, and more. Replace your Kubernetes ingress controller. Route gRPC, WebSockets, or HTTP.
      Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
      Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

      How developers use Consul, Serf, and Zookeeper
      Soundcloud uses

      Initially, Stitch only supported real-time updates and addressed this problem with a MapReduce job named The Restorator that performed the following actions:

      • Calculated the expected totals
      • Queried Cassandra to get the values it had for each counter
      • Calculated the increments needed to apply to fix the counters
      • Applied the increments

      Meanwhile, to stop the sand shifting under its feet, The Restorator needed to coordinate a locking system between itself and the real-time processors, so that the processors did not try to simultaneously apply increments to the same counter, resulting in a race-condition. It used ZooKeeper for this.

      Pinterest uses

      Like many large scale web sites, Pinterest’s infrastructure consists of servers that communicate with backend services composed of a number of individual servers for managing load and fault tolerance. Ideally, we’d like the configuration to reflect only the active hosts, so clients don’t need to deal with bad hosts as often. ZooKeeper provides a well known pattern to solve this problem.

      Chris Hartwig uses

      All our services use Consul for discovery, configuration and cluster management (auto scaling, health monitoring, dynamic reconfiguration, leader elections)

      Pinterest uses

      Zookeeper manages our state, and tells each node what version of code it should be running.

      Ralic Lo uses

      Used Zookeeper as the resource management system for Mesos/Marathon services.

      Tom Staijen uses

      Discovery service. Some configuration is stored in consul.

      Robert Hao uses

      I used Consul as config center & service discoverer.

      Nurul Ferdous uses

      Maintain a distributed cluster for search index

      Ismael Arenzana uses

      How else do you discover microservices? ;)

      exana uses

      For service discovery.
