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?
A
Explanation:
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.
Portability refers to the ability to move applications and data from one cloud provider to another with minimal friction. This directly addresses the committee’s concern about not being locked into a single cloud provider. It allows the organization to switch providers if necessary without heavy reliance on a particular provider’s proprietary technologies, which also helps in reusing components across different cloud platforms.
