Your IT steering committee has, at a high level, approved your project to begin using cloud services. However, the committee is concerned with getting locked into a single cloud provider and has flagged the ability to easily move between cloud providers as a top priority. It also wants to save costs by reusing components. Which cross-cutting aspect of cloud computing would be your primary focus as your project plan continues to develop and you begin to evaluate cloud providers?

Question

Interoperability is ability to easily move between cloud providers, by either moving or reusing components and services. This can pertain to any cloud deployment model, and it gives organizations the ability to constantly evaluate costs and services as well as move their business to another cloud provider as needed or desired. Portability relates to the wholesale moving of services from one cloud provider to another, not necessarily the reuse of components or services for other purposes. Although resiliency is not an official concept within cloud computing, it certainly would be found throughout other topics such as elasticity, auto-scaling, and resource pooling. Scalability pertains to changing resource allocations to a service to meet current demand, either upward or downward in scope.
