Redundant Array of Inexpensive Servers
<architecture> (RAIS) The use of multiple servers to provide
the same service in such a way that service will still be
available if one or more of the servers fails. The term may
or may not imply some kind of load balancing between the
servers. See cluster.
The term "RAIS" follows RAID, which describes schemes for
resilient disk storage.

Redundant Array of Inexpensive Servers
A Redundant Array of Inexpensive Servers (RAIS) or Redundant Array of Independent Nodes (RAIN) is the use of multiple servers to maintain service if one server fails. This is similar in concept to how RAID turns a cluster of ordinary disks into a single block device.
