How can we improve Microsoft Azure TCO Calculator?

utilization

Make it more obivous or simple to select the utilization of a VM. The Azure VM pricing is based on, by default, 40% utilization, meaning the VM would only be powered on for 40% of the time in Azure. This isn't realistic for lift and shift of datacenter workloads that are on 100% of the time and is producing inaccurate pricing comparisons.

    The 40% factor is the default, but can be changed within the Assumptions —> Virtualization Costs section. The rationale for 40% is that it is a combination of: (i) dev/test workloads that do not run 100% of the time and (ii) a proxy for right-sizing Azure VMs as those workloads move from on-premises into the cloud. On the second point, the most accurate way to do right-sizing is to actually collect performance data and truly select a downsized VM; however, since we don’t do that in the Calculator, we are using a reduction factor as a proxy for selecting a downsized VM. I hope that makes sense and feel free to adjust that factor for your actual scenarios.
