Microsoft E20ds v4 Azure Virtual Machine Reservation

Apply Azure Reserved Instance coverage for E20ds v4 virtual machine usage in Microsoft Azure's West Central US region. DZH318Z0CSHK-01B1 corresponds to the E20ds v4 size in the Edsv4 virtual machine family. It is a cloud licensing entitlement rather than deployable server hardware; the covered compute workload runs in Azure. E20ds v4 provides 20 vCPUs and 160 GiB of memory, placing it in Azure's memory-optimized E-series for applications whose memory requirements exceed those of general-purpose virtual machines. The 8 GiB-per-vCPU memory ratio suits memory-resident databases, in-memory caches, analytics processing, enterprise application servers, and consolidation hosts that require substantial RAM allocation. The ds designation identifies a configuration with local temporary storage and Premium SSD support for attached managed disks. Regional matching matters for this reservation: it applies to the E20ds v4 virtual machine size in West Central US rather than to a physical server or on-premises virtualization host. Select this SKU when the planned Azure compute footprint specifically uses the E20ds v4 size in that region.
