We provide a wide range of different Linux distributions and InstantApps for Instances.
You are free to bootstrap your own distribution. See the documentation on creating an image from scratch.
Scaleway’s ImageHub is a catalog of system images that allow you to deploy, manage and scale your favorite applications in seconds, from image templates.
When you request to power off your Instance, four options are available:
- Hard Reboot
- Power off
When you select the Hard Reboot option, your instance performs an electrical reboot. Your data remains on the local storage. Whenever possible, you should reboot your instance from the OS to avoid data corruption.
When you select the Power off option, all data on the local volume of your instance is transferred to a volume store, and your physical node is released back to the pool of available machines. Depending on the amount of data to be archived, the process can take time.
When you select the Terminate option, your instance and volumes are deleted. You will not be able to recover them. The flexible IP attached to your instance will not be deleted.
When you select the Standby option, your instance is stopped, but all your data remains on the local storage. Your instance is still allocated to your account, and you can restart it anytime, without delay.
Yes, each instance has two DNS hostnames associated with it:
- A public DNS hostname:
- A private DNS hostname:
Both are being updated automatically when the Instance moves to another hypervisor (and thus its IPv6, and the private IPv4, changes). You can either use these hostnames directly or configure a CNAME record linking to it.
ARM and x86-based Instances (Development Instances and General Purpose Instances) use a different instruction set and this requires to specify the architecture of the platform when creating an image from a volume.
An ARM CPU is using a Reduced Instruction Set Computing (RISC) architecture while an x86 CPU is using a Complex Instruction Set Computing (CISC) architecture. Hence, ARM architecture uses a simplified instruction set which results in power efficiency, making it ideal for mobile devices. Therefore ARM64 Instances are ideal to develop and test mobile applications.
A Marketplace is an online store that offers applications and services either built on or integrated with Scaleway’s offerings.
Scaleway marketplace image provides customers with information related to Instance images, through variants named “local-images”. This information can include the Instance zone and identification, along with constraints regarding the applicable instance types. Use the marketplace API to determine the UUID of the image you want to use. When you want to create an Instance using an image in the Instance API, you will need to specify the local-image UUID matching the zone and Instance type constraints you fetch from the marketplace API.
