Is there more to Azure VM sizes than it would appear?

  • 772

I'm trying to choose the best Azure VM for my needs but there's so many varieties it can be very confusing.

For instance I can't see why the D11 is more expensive than the D4a, when the D11 appears to be a lower spec.

There must be more to it than the basic resources listed here?

    The VM sizes which have a lowercase a in the name (e.g. D4a v3) are AMD processors. Therefore the pricing will be different.

    Finally, we are also announcing new Azure Virtual Machines as part of the Dv3 and Ev3-series—optimized for general purpose and memory intensive workloads. These new VM sizes feature AMD’s EPYC™ 7452 processor. The new general purpose Da_v3 and Das_v3 Azure Virtual Machines provide up to 64 vCPUs, 256 GiBs of RAM, and 1,600 GiBs of SSD-based temporary storage. Additionally, the new memory optimized Ea_v3 and Eas_v3 Azure Virtual Machines provide up to 64 vCPUs, 432 GiBs of RAM, and 1,600 GiBs of SSD-based temporary storage. Both VM series support Premium SSD disk storage.
