RAC and DataGuard are two different parts of the Oracle high availability technology stack.

Use RAC within a single data center so that if a single server (node) fails there is no outage.

Use DataGuard to replicate between data centers so that if there is a fire, earthquake, or other disaster there is no outage.

Both technologies can leverage TAF (transparent application failover).
