   Database servers can work together to allow a second server to
-  quickly take over if the primary server fails (failover), or to
-  allow several computers to serve the same data (load balancing).
-  Ideally, database servers could work together seamlessly.  Web
-  servers serving static web pages can be combined quite easily by
-  merely load-balancing web requests to multiple machines.  In
-  fact, read-only database servers can be combined relatively easily
-  too.  Unfortunately, most database servers have a read/write mix
-  of requests, and read/write servers are much harder to combine.
-  This is because though read-only data needs to be placed on each
-  server only once, a write to any server has to be propagated to
-  all servers so that future read requests to those servers return
-  consistent results.
