1.1.1.1. Configuring Real Servers to Synchronize Data

There are many ways an administrator can choose to synchronize data across the pool of real servers. For instance, shell scripts can be employed so that if a Web engineer updates a page, the page is posted to all of the servers simultaneously. Also, the system administrator can use programs such as rsync to replicate changed data across all nodes at a set interval.

However, this type of data synchronization does not optimally function if the configuration is overloaded with users constantly uploading files or issuing database transactions. For a configuration with a high load, a three-tier topology is the ideal solution.
