Resize an instance via the OVHcloud Control Panel
Objective
If your instance lacks resources due to increased activity or new needs, you can increase its resources in just a few clicks with the Public Cloud.
This guide explains how to resize your instance from the OVHcloud Control Panel.
Only upscaling is possible for classic models. In addition, this manipulation causes the instance to be shut down for the time of the operation.
Flex instances allow resizing to higher or lower models due to a locked single disk size.
Requirements
- A Public Cloud instance in your OVHcloud account
- Access to the OVHcloud Control Panel
Instructions
Log into the OVHcloud Control Panel, go to the Public Cloud section and select the Public Cloud project concerned. Then click on Instances in the left-hand menu.
Click on ... to the right of the instance, and select Edit. You can also access this action from the instance details by clicking on its name, then on Modify model.
In the new tab, scroll down to the Template section to select the model of your choice.
For classic models, you can switch to any flavor that has a similar or bigger disk. You can't switch to a model with a smaller disk.
Only Flexible instances can be upgraded and downgraded while maintaining a fixed disk size of 50GB.
If your disk is equal to or smaller than 50GB, you can switch to a Flexible instance if desired.
If you are editing a flex instance, you cannot revert to a classic instance via the Control Panel. For more information, consult the guide on Revert a flex instance.
Once the selection has been made, click on Modify template to confirm your choice.
