Setting up distributed memcached (Intermediate)

One of the most common use cases of using memcached is to build a distributed cache environment over multiple machines in a cluster. The setup allows you to scale up memcached horizontally by adding more machines to a cluster, you expand the total memory available for your application as a cache. The benefit of having a horizontally scalable caching, is that you are not limited by the amount of RAM you can install in a single server any more. It also means that you can utilize some of the free memory you have in your web server or so, and collectively you will have a distributed memcached environment with a large single virtual memory pool for your caching needs.
