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.

Explanation
Sandboxing involves the segregation and isolation of information or processes from other information or processes within the same system or application, typically for security concerns. Sandboxing is generally used for data isolation (for example, keeping different communities and populations of users isolated from others with similar data). In IT terminology, pooling typically means bringing together and consolidating resources or services, not segregating or separating them. Cell blocking and fencing are both erroneous terms.

Explanation
With Infrastructure as a Service (IaaS), the cloud customer is responsible for deploying and maintaining its own systems and virtual machines. Therefore, the customer is solely responsible for patching and any other security updates it finds necessary. With Software as a Service (SaaS), Platform as a Service (PaaS), and Desktop as a Service (DaaS), the cloud provider maintains the infrastructure components and is responsible for maintaining and patching them.

Explanation:
Removing antimalware agents. Hardening the operating system means making it more secure. Limiting administrator access, closing unused ports, and removing unnecessary services and libraries all have the potential to make an OS more secure. But removing antimalware agents would actually make the system less secure. If anything, antimalware agents should be added, not removed.

Explanation
Wholesalers or distributors are generally not regulated, although the products they sell may be.
