This guide will show you what Serf is, explain the problems Serf solves, compare Serf versus other similar software, and show how easy it is to actually use Serf. If you're already familiar with the basics of Serf, the <a href="/docs/">documentation</a> provides more of a reference for all available features.</p> <h2 id=toc_1>What is Serf?</h2> <p>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.</p> <p>Serf uses an efficient <a href="/docs/internals/gossip.html">gossip protocol</a> to solve three major problems:</p> <ul> <li><p><strong>Membership</strong>: Serf maintains cluster membership lists and is able to execute custom handler scripts when that membership changes. For example, Serf can maintain the list of web servers for a load balancer and notify that load balancer whenever a node comes online or goes offline.</p></li> <li><p><strong>Failure detection and recovery</strong>: Serf automatically detects failed nodes within seconds, notifies the rest of the cluster, and executes handler scripts allowing you to handle these events. Serf will attempt to recover failed nodes by reconnecting to them periodically.</p></li> <li><p><strong>Custom event propagation</strong>: Serf can broadcast custom events to the cluster. These can be used to trigger deploys, propagate configuration, etc.</p></li> </ul> <p>See the <a href="/intro/use-cases.html">use cases page</a> for a list of concrete use cases built on top of the features Serf provides. See the page on <a href="/intro/vs-other-sw.html">how Serf compares to other software</a> to see just how it fits into your existing infrastructure. Or continue onwards with the <a href="/intro/getting-started/install.html">getting started guide</a> to get Serf up and running and see how it works.</p> </div> </div> </div> <div id=footer> <div class=container> <div class=footer-links> <ul class="main-links nav navbar-nav rls-s
