WARNING: Resizing an instance in the "Active" state will reboot the instance, so be sure to save any active work before attempting.


A variety of instance sizes are available on Red Cloud. The instance size (or type) defines how much memory (RAM) is available, the amount of per-instance storage (typically available through /dev/vdb in Linux instances), and the number of CPU cores available.

Resizing an instance allows you to dynamically control your work process. During periods of heavy development, you may only want a small instance type to develop on, but during periods of heavy computational activity, a large instance (or multiple large instances) may be desirable.

The options can be found by clicking on the Resize Instance option in the menu for the instance on the right side of the instances listing page:

This option is only available for instances whose state is either "Active" or "Stopped". The dialog for resizing the instance type is shown below:

Simply select the new flavor you would like and then select "Resize".
