Microsoft E16-4ds v4 Azure VM Reservation

Apply reserved-instance coverage to eligible Microsoft Azure E16-4ds v4 virtual machine usage in the US Central region. DZH318Z0CSHK-025Z identifies this specific Azure reservation SKU, tying coverage to the Edsv4 series and the named VM size rather than to a general compute commitment. It fits environments with predictable utilization that need reservation coverage matched to a defined Azure VM configuration and region. The E16-4ds v4 configuration provides 4 vCPUs and 128 GiB of memory, placing it in Azure's memory-optimized E-series. Its constrained-core design retains the E16 memory profile while limiting available compute cores, which can suit workloads whose memory requirement exceeds their CPU requirement. The ds designation identifies support for Premium SSD storage and local temporary storage, allowing the VM configuration to support storage-intensive application layouts where appropriate. Apply this reservation where deployed usage aligns with the E16-4ds v4 size and US Central region. A reserved instance changes the commercial coverage applied to qualifying virtual machine usage; it does not create a VM or configure its operating system, virtual network, disks, or application stack. Keep the VM size and region aligned with the covered workload when planning Azure capacity and runtime placement.
