SQL Anywhere supports database mirroring and Veritas Cluster Server to provide high availability. Both of these configurations provide alternate database servers that can run a database should the database server currently running the database become unavailable.

If you want to distribute workloads, then you should also consider whether using read-only scale-out is an appropriate solution. Read-only scale-out can be used with database mirroring. See SQL Anywhere read-only scale-out and Read-only scale-out in a database mirroring system.

For information about using high availability and/or read-only scale-out for hosting web applications, see SQL Anywhere web services high availability and scale-out solutions.
