Explanation

Multitenancy is a key characteristic of the public cloud, and an important risk. Although public cloud providers strive to ensure isolation between their various customers, the infrastructure and resources in the public cloud are shared. Inherent risks in a shared environment include misconfigurations, inadequate or ineffective processes and controls, and the "noisy neighbor" problem (excessive network traffic, disk I/O, or processor use can negatively impact other customers sharing the same resource). In hybrid and multicloud environments that connect numerous public and/or private clouds, the delineation becomes blurred, complexity increases, and security risks become more challenging to address.
