Cloud Federation is an arrangement in which multiple independent cloud environments work together so resources, services, or workloads can be shared and coordinated across providers. A federated setup can connect private, public, or hybrid clouds while allowing applications and users to access resources across these separate environments.
Cloud Federation is useful when organizations need to distribute workloads, combine capabilities from different cloud providers, or maintain flexibility instead of relying on a single platform. It can support workload portability, resource sharing, and resilience, but requires compatible identity management, networking, security policies, and governance across participating clouds.
