Which approach has a goal of ensuring that a given workload can be moved with minimal changes between cloud providers?

• A. On-prem virtualization
• B. Containerization
• C. Bare-metal provisioning
• D. Vendor-specific APIs

Answer: (B)

Containers enable moving a workload between cloud providers with minimal changes because they package the application and all its runtime dependencies into a single, portable image. This image runs on any host that has a compatible container runtime, so the same container behaves the same across different clouds. When you pair containers with an orchestration system like Kubernetes, you can deploy the same workload definitions across providers, further reducing the need to rewrite or reconfigure components for each environment. The result is a consistent execution environment regardless of the underlying infrastructure.

On-prem virtualization ties you to a specific hypervisor and environment, making changes needed to move to another provider more than minimal. Bare-metal provisioning is hardware-bound and inherently non-portable across cloud providers. Vendor-specific APIs lock you into one provider, requiring substantial changes to switch clouds.
