What Determines How Many VMs I Can Create?

There are three factors that determine how many VMs you can create:

• OCPU: The maximum number of VMs varies according to the shape selected.
• Memory: The maximum number of VMs is based on the Flex shape selected and the Allocated Memory setting. This restriction is used for Flex shapes only.
• Volume: The maximum number of VMs is based on the Volume Size setting.

After you specify a volume size (in GB), the Add VM Build Executor dialog displays real time numbers for OCPU and Memory, just below the line that tells you how many VMs are available for you to use. These numbers come directly from the OCI Console.

You might notice that Quantity isn’t on the list. The quantity of VMs that you actually create has no impact on the limits. The limits represent the maximum numbers of what you could use but VB Studio doesn’t restrict what you can create. This is actually beneficial, since availability constantly changes. Instead, the runtime simply limits what you can use in real time.
