Data Layer
CCF Data layer is provided by SQL Server. CCF recommends failover clustering or database mirroring to ensure high availability of solutions:
Failover Clustering: SQL Server failover clustering provides high-availability support for an entire SQL Server instance. SQL Server failover clusters are built on top of Windows Server failover clusters. To create a SQL Server failover cluster, you need to first create the underlying Windows Server failover cluster.
Database Mirroring: Database mirroring involves two copies of a single database that typically reside on different computers. At any given time, only one copy of the database is currently available to clients
