Microsoft E20DS V4 Azure VM Reservation for US West 2

Apply Microsoft Azure reserved-instance pricing to eligible E20ds v4 virtual machine compute usage in the US West 2 region. DZH318Z0CSHK-0198 is a CSP Azure Reserved Instance offering tied to the E20ds v4 size, rather than a deployable virtual machine image or a perpetual software license. The reservation is intended for organizations standardizing qualifying Azure usage on this specific VM family, size, and region combination. E20ds v4 provides 20 vCPU and 160 GiB of memory, placing it in Azure's memory-optimized E-series. That balance suits workloads where memory capacity is a primary sizing factor, including larger application services, in-memory processing tiers, caching layers, and database-related server roles. The ds designation identifies a size with local temporary storage and Premium SSD capability, allowing attached Premium SSD managed disks where the workload requires that storage tier. Use this reservation when the deployed or planned Azure compute use matches E20ds v4 in US West 2. VM reservations are specific to the qualifying compute configuration, so the VM family, size, and regional placement matter when matching usage. This offering distinguishes itself within the Edsv4 range through its 20 vCPU and 160 GiB memory allocation, providing a mid-range memory-optimized option without changing to a different Azure VM series.
