Microsoft E20ds v4 Azure VM Reserved Instance

Reserve Microsoft Azure Virtual Machines EDSv4 Series capacity for the E20ds v4 size in the West Central US region. DZH318Z0CSHK-01B4 is a CSP Azure Reserved Instance for matching virtual machine usage rather than a deployable virtual machine image. It applies to the E20ds v4 configuration, which provides 20 vCPUs and 160 GiB of memory for workloads that need a high memory-to-core ratio. The E-series is Azure's memory-optimized virtual machine family. An E20ds v4 instance fits applications whose working sets, caches, database buffers, and in-memory processing requirements benefit from 160 GiB of memory without moving to a larger compute size. The 20-vCPU allocation supports parallel application services, database engines, and data-processing roles that need both processor capacity and substantial memory. Within the EDSv4 family, the E20ds v4 designation identifies a specific memory-optimized size with local temporary storage indicated by the d suffix and Premium SSD storage support indicated by the s suffix. The regional designation matters: this reservation is for West Central US virtual machine usage. Match the selected Azure deployment region and E20ds v4 size to the reserved configuration before assigning the reservation.
