Microsoft E20s v4 US Central Azure VM Reservation

Reserve Azure compute usage for the E20s v4 virtual machine size in the US Central region. Microsoft DZH318Z0CSHL-031Z is an Azure Reserved VM Instance offering for the ESv4 series, associating the reservation with eligible matching virtual machine consumption rather than deploying a virtual machine by itself. It is suited to workloads with predictable, continuing use of this specific regional VM size. E20s v4 is a memory-optimized Azure VM configuration with 20 vCPUs and 160 GiB of memory. That capacity profile fits services that need more memory per CPU than general-purpose compute, including database tiers, in-memory application services, analytics components, and enterprise application servers. The “s” designation identifies support for Premium SSD storage, allowing the deployed VM configuration to use Premium SSD managed disks where required. The reservation is specific to the ESv4 family, E20s v4 size, and US Central geography named for this product. It affects eligible compute billing for the matched Azure usage; it does not create a running VM, supply an operating system, or include application software. Confirm the target workload is deployed as an eligible E20s v4 virtual machine in US Central before assigning reservation coverage.
