Explanation
Within a SaaS implementation, the cloud customer licenses the use of the software from the cloud provider because SaaS delivers a fully functional application to the customer. With SaaS, the cloud provider is responsible for the entire software application and any necessary infrastructure to develop, run, and maintain it. The purchasing, development, and maintenance are fully the responsibility of the cloud provider.

A process is an administrative control; sometimes, the process includes elements of other types of controls (in this case, the access control mechanism might be a technical control, or it might be a physical control), but the process itself is administrative. Keystroke logging is a technical control (or an attack, if done for malicious purposes, and not for auditing); door locks are a physical control; and biometric authentication is a technological control.

Explanation
The concept of shares within a cloud environment is used to mitigate and control the request for resource allocations from customers that the environment may not have the current capability to allow. Shares work by prioritizing hosts within a cloud environment through a weighting system that is defined by the cloud provider.
When periods of high utilization and allocation are reached, the system automatically uses scoring of each host based on its share value to determine which hosts get access to the limited resources still available. The higher the value a particular host has, the more resources it will be allowed to utilize.
