Microsoft E64-16ds v4 Azure Virtual Machine Reservation

Apply Azure Reserved Instance pricing to Microsoft Azure E64-16ds v4 virtual machine usage in US East 2. This reservation corresponds to a constrained-core member of the Azure E v4 memory-optimized virtual machine range. It provides 16 vCPUs while retaining the 504 GiB memory allocation associated with the larger E64 platform, supporting applications whose memory requirement is higher than their sustained CPU requirement. The E64-16ds v4 configuration suits memory-intensive services such as large database instances, in-memory caches, analytics processing, and enterprise application tiers where controlling active core count matters. Its 16-vCPU configuration can help align compute allocation with software licensing limits while preserving a large memory footprint. The ds designation indicates Premium SSD support for attached managed disks, allowing storage performance to be selected separately for the workload. DZH318Z0CSHK-01XC applies to this E64-16ds v4 Azure virtual machine reservation specifically in the US East 2 region. Select it when the deployed workload matches the named VM size and regional scope. The constrained-core design distinguishes this configuration from standard full-core E-series sizes by pairing reduced active vCPU capacity with the memory resources of the E64 platform.
