Microsoft D4a v4 Azure Virtual Machine Reservation

Apply reservation coverage for qualifying Azure D4a v4 virtual machine usage in the US West Central region. The D4a v4 VM size supplies 4 virtual CPUs and 16 GiB of memory, placing it in the Dav4 family of AMD-based Azure compute sizes. Microsoft DZH318Z0CM2B-00X2 identifies the CSP Azure Reserved Instance offering associated with that regional D4a v4 usage. A reserved instance applies commercial coverage to eligible compute consumption rather than creating or configuring a virtual machine. Existing or newly deployed workloads must use the matching D4a v4 size and run within the US West Central Azure region for the reservation scope to align. VM operating system selection, attached storage, networking, application software, and deployment configuration remain separate workload choices. Within the Dav4 VM family, this selection is distinguished by its D4a v4 size designation, which fixes the compute and memory profile at 4 vCPU and 16 GiB. The regional designation is also material: this reservation applies to usage in US West Central rather than acting as a cross-region compute selection. It suits environments standardizing on that specific VM size for consistently sized application, service, or infrastructure workloads.
