CPU Cores and Device Slots

If you're on a monthly billing plan, your account is provisioned with a number of CPU Cores and Device Slots.

  • CPU Cores are the combined maximum number of cores you can have across all of your devices at any one time.
  • Device Slots are the combined maximum number of devices you can have in your devices list at any one time.

You can find out your current usage on the devices page and you can see how many CPU Cores a device requires before you create it. If you delete a device you will get the number of CPU Cores it occupied and Device Slot credited back to your account.

These CPU cores correspond to the number of CPU cores available on the Arm servers assigned to that company's account. Each virtual device requires a certain number of CPU cores to run.

For every two active CPU cores allotted to your account, you can store up to five devices in an Off state.

In certain scenarios, it’s also possible to configure the number of cores and RAM a virtual machine instance uses, under Advanced Settings in our UI. During creation, it changes the default cores and RAM. After creation, it takes effect on the next boot.
