A cloud risk registry is primarily used to identify and manage risks associated with cloud services. It serves as a tool for documenting, tracking, and assessing potential risks to the organization that arise from using cloud services. This includes risks related to security, compliance, availability, and performance. The risk registry helps organizations prioritize and mitigate these risks effectively to ensure the security and resilience of their cloud infrastructure.
Establishing SLAs is related to cloud contract management but not the primary purpose of a risk registry.
Monitoring real-time cloud performance is a performance monitoring task, not the focus of a risk registry.
Managing cloud account credentials is an aspect of identity and access management, not related to risk registries.
