Description
This policy identifies Azure Storage Accounts that are provisioned in Azure regions known to have higher pricing compared to nearby alternatives.
Rationale
Selecting the appropriate Azure region is essential for optimizing both cost and performance. Service pricing can vary across regions due to factors such as infrastructure expenses, energy costs, and local taxes. Deploying workloads in cost-efficient regions can result in substantial savings on monthly Azure expenditures.
Impact
Migrating workloads to different regions requires careful planning to avoid service disruptions and to ensure latency, compliance, and data sovereignty requirements continue to be met.
Audit
This policy flagged an Azure Storage Account as INCOMPLIANT if it is running in one of the following regions identified as less cost-efficient:
