A cloud administrator is reviewing the current private cloud and public law environment, and is building an optimization plan. Portability is of great concern for the administrator so resources can be

Serverless computing abstracts infrastructure entirely but ties execution to a specific cloud provider's runtime, reducing portability rather than improving it.

A CDN (Content Delivery Network) is used to cache and distribute content geographically to reduce latency, not to make application workloads portable between cloud environments.

Containers encapsulate an application along with all its runtime dependencies into a standardized image, enabling workloads to run consistently across different environments regardless of the underlying infrastructure. This abstraction from the host OS is what makes containers the primary technology for cloud portability. Tools like Docker and Kubernetes are designed specifically to orchestrate containers across hybrid and multi-cloud scenarios.

Deduplication is a storage optimization technique that removes redundant data to save space, and has no bearing on workload portability between environments.
