In this case, the application deployment topology is optimized for handling regional disasters when all application components need to fail over together. The diagram below shows this topology. For geographic redundancy, the application's resources are deployed to Region A and B. However, the resources in Region B are not utilized until Region A fails.

The *Demo-LoadGenerator* PowerShell script starts a workload that runs against all tenant databases. The real-world load on many SaaS apps is sporadic and unpredictable. To simulate this type of load, the generator produces a load with randomized spikes or bursts of activity on each tenant. The bursts occur at randomized intervals. It takes several minutes for the load pattern to emerge. Let the generator run for at least three or four minutes before you monitor the load.
