Resize Instances

Reviewed on August 14, 2026

You can adjust the size of your Scaleway Instances, also known as vertical scaling, to match changing workload demands and optimize resource usage.

Vertical scaling lets you increase or decrease computational power without destroying and recreating your Instance. Use it to scale up for increased traffic, scale down to reduce costs, or reconfigure an Instance to better fit your application requirements.

The flexible Scaleway infrastructure lets you modify CPU and RAM allocation, and manage your Block Storage volumes, directly from the console, so your resources always match your needs.

Alternatively, you can also resize your Instance using the command line by following the guide Changing the commercial type of an Instance with the API or CLI.

Before you start

To complete the actions presented below, you must have:

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization
• An Instance using Block Storage volumes

Change the offer type of active Instances

Changing the offer type of an active Instance includes upgrading within the same Instance generation (for example, from a BASIC3-X6C-12G to a BASIC3-X6C-24G offer) or to a more recent generation (for example, from a BASIC3 to a POP2 offer).

1. In the Compute section of the side menu, click CPU & GPU Instances. The Instances page opens.
2. Select the Availability Zone (AZ) from the dropdown (e.g., PAR1) to view resources in the selected AZ.
3. Click the Instance you want to resize. Its Overview page opens.
4. Click Change offer in the Instance information section of the overview page. The change offer type page opens.
5. Select a new Instance configuration from the list of available offers. Recommended configurations are highlighted.
   • To stay within the same generation, choose another offer from the same commercial range.
   • To move to a more recent generation, choose an offer from a different commercial range further down the list.
6. Review pricing and compare the monthly cost of the new configuration with your current offer.
7. Click Change offer type to proceed. This upgrades your Instance, which reboots in the process, resulting in up to five minutes of downtime.

Change the offer type of an end-of-life Instance

When an Instance reaches End of Life, Scaleway displays an alert banner on the Instance Overview page, informing you that you must upgrade the Instance, and recommends an equivalent offer to migrate to.

1. In the Compute section of the side menu, click CPU & GPU Instances. The Instances page opens.
2. Select the Availability Zone (AZ) from the dropdown (e.g., PAR1) to view resources in the selected AZ.
3. Click the Instance you want to upgrade. Its Overview page opens.
4. Click Upgrade in the Instance information section of the overview page. The Change offer type page opens.
5. Select a new Instance configuration from the list of available offers. The recommended offer is preselected and appears at the top of the list.
6. Review pricing and compare the monthly cost of the new configuration with your current offer.
7. Click Change offer type to proceed. This upgrades your Instance, which reboots in the process, resulting in up to five minutes of downtime.
