Microsoft D64d v4 Azure Virtual Machine Reserved Instance

Apply Azure Reserved Instance coverage to D64d v4 virtual machine usage in the US North Central region. The D64d v4 configuration provides 64 vCPUs and 256 GiB of memory, placing it in the high-capacity end of the Dd v4 virtual machine series for workloads that require substantial parallel compute resources and memory per instance. The D64d v4 size includes local temporary storage. That storage is attached to the host and is intended for temporary data such as caches, scratch files, buffers, and application working space. Applications must keep durable data on persistent Azure storage, because data held on temporary storage is not intended as durable application storage. Microsoft DZH318Z0D1L2-016D applies to the D64d v4 Azure virtual machine configuration in US North Central. It suits deployments where the virtual machine size, region, and expected runtime are already established, including large application servers, analytics processing nodes, build systems, and compute services with sustained resource requirements. The reservation is specific to the named Azure VM series and size, so the deployed compute usage must align with D64d v4 eligibility for the reservation benefit to apply.
