For example, Puppet provides exported resources and Chef has node searching. As an example, if you generate a config file for a load balancer to include the web servers, the config management tool is being used to manage membership.</p> <p>However, none of these config management tools are designed to perform this task. They are not designed to propagate information quickly, handle failure detection, or tolerate network partitions. Generally, they rely on very infrequent convergence runs to bring things up to date. Lastly, these tools are not friendly for immutable infrastructure as they require constant operation to keep nodes up to date.</p> <p>That said, Serf is designed to be used alongside config management tools. Once configured, Serf can be used to handle changes to the cluster and update configuration files nearly instantly instead of relying on convergence runs. This way, a web server can join a cluster in seconds instead of hours. The separation of configuration management and cluster management also has a number of advantageous side effects: Chef recipes and Puppet manifests become simpler without global state, periodic runs are no longer required for membership updates, and the infrastructure can become immutable since config management runs require no global state.</p> </div> </div> </div> <div id=footer> <div class=container> <div class=footer-links> <ul class="main-links nav navbar-nav rls-sb"> <li><a href="/intro/index.html">Intro</a></li> <li class=active><a href="/docs/index.html">Docs</a></li> <li><a href="/community.html">Community</a></li> </ul> <ul class="buttons nav navbar-nav rls-sb"> <li class=first><a href="/downloads.html">Download</a></li> <li><a href="https://github.com/hashicorp/serf">Github</a></li> </ul> </div> <div class=footer-logo> <span></span> </div> <div class="footer-hashi os"> <span>© 2013.
