Explanation
With multitenancy, where different cloud customers all share the same physical systems and networks, data classification becomes even more important to ensure that the appropriate security controls are applied immediately to prevent any potential leakage or exposure to other customers. Portability refers to the ability to move easily from one cloud provider to another. Interoperability refers to the ability to reuse components and services for different uses. Reversibility refers to the ability of the cloud customer to quickly and completely remove all data and services from a cloud provider and to verify the removal.

Contractual requirements can carry financial or contractual impacts for the improper use or disclosure of PII data, but not legal or criminal penalties that are officially enforced.

The standards put out by the International Data Center Authority (IDCA) have established the Infinity Paradigm, which is intended to be a comprehensive data center design and operations framework. The Infinity Paradigm shifts away from many models that rely on tiered architecture for data centers, where each successive tier increases redundancy. Instead, it emphasizes data centers being approached at a macro level, without a specific and isolated focus on certain aspects to achieve tier status.
