Setup 2 DCs with connection between them (direct or tunnels or both) - both
using BGP, and announcing the IPs to the upstream ASes.

The bigger issue will be with things like
 * dual active, quorums, fencing
 * database replication
 * application support of moving back and forth...

Is this the correct solution for his requirements?
Would a cloud provider make more sense for this scenario?

These are all questions that can not simply be solved via a 2 min email.
