13. Cloud-Bursting Scenarios
Assume a conservative enterprise
– Productive back-office workloads (like ERP) have to be private due to compliance
– Productive front-office workloads (like CRM) can go to virtual private clouds
– Only simulations/test/dev workloads can go to public clouds
Workloads will be pushed from private clouds to providers and vice versa!
