Concepts

Our service relies on a few organizing concepts:

• Tenant: The customer receives a tenant to create accounts and manage resources. Virtual Machines (VM) consumption is tracked by tenant.

• Account: Accounts are associated with a tenant and allow its users to authenticate to the cloud platform to create, access and delete cloud resources.

• Network: A network contains the IPv6 address spaces for your VMs.

• Cluster: Clusters reflect our datacenters. A6000 clusters are currently located in Norway, A100 clusters in Sweden.

• Bare Metal Instance (BM): A BM offers non-virtualised access to the high-performance computing server located in our datacenters, and offers a full set of computing resources on that server based on a flavor.

• Virtual machine (VM): A VM represents a virtualized slice of the high-performance computing servers located in our datacenters, and offers a specific set of computing resources based on a flavor.

• Flavor: A flavors is a pre-defined configuration of computing resources (GPUs, vCPUs, RAM, Storage) which we offer with our VMs.

• Image: VMs are initialized with an image of an operating system.

• UUID: Universally unique identifiers (UUIDs) are 128-bit labels to globally identify resources on the platform. All instances (e.g., tenants, accounts, or VMs) have individual uuids.​

Basic usage

Each item in a response has a so-called uuid. The uuid is a unique identifier of an item which must be entered in an API call so the system understands which item to process. For example, to boot your VM with an Ubuntu 22.04 LTS operating system, enter the uuid of this image in the appropriate field of the POST /vm/vms API call.

If you want to get more information about a certain object (e.g. of the Ubuntu 22.04 LTS OS image), simply use one of the Info calls. That’s the response of the GET /info/images API call:

Understanding the API info call

There is one call that returns information about all the components that are required to start a VM - the GET /info API call. It is the baseline of this API.

The tenant is the most important item as it is required to create all components of a VM. Tenants are listed under customer_info in the response. Please make sure that the tenant uuid is consistent throughout all the components of a VM, such as ssh-key, network, IPv4 address and the VM itself!
