VMC Sizer: Understand your VMware Cloud on AWS Costs

As multi-cloud strategies continue to evolve, the cost of moving to the cloud will continue to be an important topic among decisions makers. In order to better understand the total cost of ownership (TOC), VMware Cloud on AWS has created a simple cost estimating tool for customers. Introducing VMC Sizer. With VMC Sizer, you can choose your workload type (VDI, Databases (Oracle or MSSQL), or General VMs), as well VM specifics such as vCPU, vRAM, IO, storage requirements and much more. With this tool, we have taken the guesswork out of understanding the costs associated with running workloads in VMware Cloud on AWS. In order to get a holistic view of costs, you have the option of adding several workload profiles to your profile where you can see all the costs of your Oracle, Microsoft SQL, VDI, and General Purpose VM configurations.

Getting the recommendations and TCO for your workloads only takes three simple steps.

  • Define your workloads
  • Review the recommendations based on your inputs
  • Create an account and review your VMConAWS TCO.

Workload Profiles

This is where the rubber meets the road but it’s important for you to understand that the information you enter from this point forward will determine the results of the recommendations and TCO of your SDDC in VMConAWS. The first settings you need to verify is your Cluster Settings, specifically your desired CPU Headroom and Fault Tolerance. The Server Configuration is static as all VMware Cloud on AWS hosts are all i3 instances.

Cluster Settings

Once you are comfortable with your cluster settings, you have the option of creating more than one workload profile so why not create one for your General VMs as well as your databases and VDI?! After selecting your workload type and VM count, you have two options for calculating storage. You can enter the amount of storage per VM or, if you are unsure how much you need per VM, you can enter the cluster storage requirement.

The next step in the process is to define additional workload settings such as vCPU, vRAM properties as well as IOPs and Dedup.  Keep in mind that your choices around IOPs and Dedup will change the size of your SDDC clusters.


Once all the data has been entered, select “Recommendation” to move to Step 2. I will cover the Recommendation and TCO section in Part 2. In the meantime, take the tool for a spin and enjoy!! VMCSizer
