Virtualisation is the foundation of cloud infrastructure, requiring virtualisation-aware security to maximise protection and performance. However, moving applications and data into the cloud also introduces unique risks—in all three cloud models: private, public, and hybrid. A comprehensive, adaptive, and efficient approach to cloud protection is needed regardless of which cloud model businesses deploy or how their cloud computing needs evolve.

This paper discusses each of the three cloud models, their unique security risks, and the security solutions that best address those risks. With the right security, companies can safely implement any of the cloud models, even if those companies are subject to strict data privacy regulations. When selecting a cloud model, businesses should consider how it will impact their business objectives, security and compliance requirements, and IT resources.
