Microsoft E64-32AS_V4 Azure VM Reserved Instance

Apply a Microsoft Azure Reserved Instance to eligible usage of the E64-32AS_V4 virtual machine size in the US South Central region. DZH318Z0CM2D-0193 maps to the AMD-based EAs v4 family and is intended for workloads where the selected Azure VM size, region, and reservation must align. It is a cloud service entitlement rather than shipped hardware. The E64-32AS_V4 is a constrained-vCPU configuration with 32 vCPUs and 504 GiB of memory. That combination retains the high-memory profile associated with the E64as v4 platform while limiting the available CPU count. It suits memory-heavy application tiers, database services, analytics processes, and enterprise workloads where memory demand is greater than the required CPU allocation. Use this reservation when the deployed or planned Azure workload is specifically sized for E64-32AS_V4 in US South Central. The EAs v4 family uses AMD processors, and the constrained-vCPU format can help align virtual CPU-based software requirements with an application’s actual compute needs. Confirm the active Azure VM configuration and region before assigning the reservation so eligible usage can receive the reserved-instance benefit.
