-# Use Cases
-
-At this point you should know [what Serf is](/intro/index.html) and
-the high-level features Serf provides. This page lists a handful of
-concrete use cases of Serf. Note that this list is not exhaustive by
-any means. Serf is a general purpose tool and has infinitely many more
-use cases. But this list should give you a good idea of how Serf 
-might be useful to you.
-
-It is important to remember that all the use cases available below
-require _no centralized state_, are masterless, and are completely
-fault tolerant.
-
-#### Web Servers and Load Balancers
-
-Using Serf, it is trivial to create a Serf cluster
-consisting of web servers and load balancers. The load balancers can
-listen for membership changes and when a web server comes online or goes
-offline, they can update their node list.
-
-#### Clustering Memcached or Redis
-
-Servers such as Memcached or Redis can be easily clustered by creating
-a Serf cluster for these nodes. When membership changes, you can update
-something like [twemproxy](https://github.com/twitter/twemproxy) or your
-own application's list of available servers.
-
-#### Triggering Deploys
-
-Serf can send custom events to a Serf cluster. If you cluster your web
-applications into a single cluster, you can use Serf's event system to
-trigger things such as deploys. Just call `serf event deploy` and have
-event handlers installed on all the nodes and the entire cluster will
-receive this message within seconds and begin deploying.
-
-#### Updating DNS Records
-
-Keeping your internal DNS servers updated can be a finicky process.
-By using Serf, the DNS server can know within seconds when nodes join,
-leave, or fail, and can update records appropriately. No more stale DNS
-records, or waiting for a Chef or Puppet run to clear out the records
-within X minutes. With Serf, the records can be updated nearly instantly.
-
-#### A Building Block for Service Discovery
-
-One of the most difficult parts of service discovery is simply knowing
-what nodes are online, at what addresses, and for what purpose. An effective
-service discovery layer can easily be built on top of Serf's seamless
-membership system. Serf handles all the problems of keeping an up-to-date
-node list along with some information about those nodes. The service
-discovery layer then only needs to answer basic questions above that.
