3. Set up a database cluster
At a specified level you will need to setup a databases cluster. A database cluster is just a group of servers that all have a duplicate of your database running. Your website will then link to a random server in the cluster to get it truly is data. So if you have a database cluster with 3 servers, every single server will deal with 1/three of the databases visitors. The most common databases cluster set up is learn/slave, which indicates that there is one of your servers set up as the master and the relaxation are regarded as slaves.
