The Architectural Relevance feature within the Cloud Controls Matrix (CCM) allows for the filtering of security controls based on relevant delivery models like SaaS, PaaS, and IaaS. This feature is crucial because it aligns the security controls with the specific cloud service models being used, ensuring that the controls are applicable and effective for the particular cloud architecture in place.
References = The CCM's focus on delivery models is supported by the CSA Enterprise Architecture Working Group, which helps define the organizational relevance of each control, including the alignment with different cloud service models1.
