Microsoft E20ds v4 Azure VM Reserved Instance

Apply reserved-instance pricing to Microsoft Azure E20ds v4 virtual-machine compute in US East 2. The E20ds v4 profile supplies 20 vCPU and 160 GiB of memory, placing it in the memory-optimized EDSv4 family for services that hold substantial working sets in RAM. Its 400 GiB local temporary disk supports cache, scratch, and transient-processing data that can be recreated. DZH318Z0CSHK-01X0 maps to the E20ds v4 reservation in the US East 2 region. The reservation applies to matching Azure VM compute usage rather than supplying a VM image, operating system, storage account, or application configuration. That distinction matters when sizing a deployment: select the VM image and managed disks separately, while keeping the reserved compute profile aligned to the E20ds v4 size and region. Within the EDSv4 family, the E20ds v4 combination pairs 20 vCPU with 160 GiB memory and includes 400 GiB of local temporary storage. The “d” designation denotes that local disk, while “s” indicates Premium SSD support for attached managed disks. Use local storage only for nonpersistent data; place databases, user content, and other persistent data on managed disks selected for the workload.
