A financial institution has highly sensitive customer data that must remain within their on-premises data centers due to strict regulatory compliance. However, they want to leverage cloud services for less sensitive, burstable workloads like development and testing environments. Which cloud deployment model would best meet these needs?
- AHybrid Cloud
- BCommunity Cloud
- CPrivate Cloud
- DPublic Cloud
Show answer & explanationAnswer & explanation
Correct answer: A. Hybrid Cloud
A hybrid cloud model allows the financial institution to keep sensitive data and applications in their secure, on-premises private cloud (meeting compliance) while utilizing the agility and scalability of a public cloud for non-sensitive, burstable workloads like dev/test environments. This combines the best of both worlds.
Why the other options are wrong
- B. Community cloud is for shared interests, not combining on-prem and public for one org.
- C. Private cloud alone cannot leverage the burstable nature and cost-efficiency of public cloud for dev/test without significant CapEx.
- D. Public cloud alone cannot meet strict on-premises data residency requirements.
Hybrid Cloud
A cloud deployment model that combines a private cloud with a public cloud, allowing data and applications to be shared between them. This enables organizations to leverage the benefits of both environments.
- Interconnects private and public cloud resources.
- Offers flexibility for sensitive data (private) and scalable workloads (public).
- Requires robust integration and management.
- Common for 'cloud bursting' and phased migrations.
Memory trick: Hybrid cloud mixes the best of your home and the public square.
