A multiple-server installation consists in installing Fluid Topics on several servers in order to distribute the load and/or provide redundancy for critical components. By default, these servers are located in a single data center. Upon request, it is possible to distribute a multi-server installation across several data centers in different regions of the world. For more information, see Global Presence.
