Your application will grow in time, and so will your virtual machines! During the life of your project you will be able to resize your instance up and down, scaling its service level (the combination of CPU’s cores and RAM) and its disk size, optimizing it for your needs.

Select the instance you wish to operate on, and from the instance detail you will be able to access the scaling interface.


Please note that every scaling operation needs to be performed on a stopped instance.

Scaling the Service Level

Scaling your CPU’s cores and the RAM of your machine is pretty straightforward: stop your instance, access the scaling view, choose your new Service Level and restart when finished. Remember that some Service Levels may be unavailable due to eventual restrictions of your selected operating system.

Scaling the disk size

As for scaling the Service Level, scaling your disk size is easy. You can resize your volume up by steps of 1 GB.

Here are the disk size limits per service offering:

  • Micro: 200 GB
  • Tiny to Large: 400 GB
  • Extra-Large to Mega: 800 GB
  • Titan to Jumbo: 1600 GB

For Linux OS, filesystem resize happens at boot time automatically. For Windows OS, you will need to extend the partition size from Disk Management after boot.

Downscaling of your disk is not allowed since it’s hard to safely assume where data is written on the volume, and you may end up losing information.
