Flavors, quotas and reference¶
Flavor families¶
Flavors define the CPU, memory, and local disk of an instance. The
authoritative list is in the dashboard
(openstack flavor list); the families are:
b2.*(no local disk). The name encodes CPU and RAM, for exampleb2.c4r8is 4 vCPU and 8 GB RAM. These flavors have no local disk, so boot them from a volume.l2.*(local NVMe disk). Same CPU/RAM naming with a disk size suffix, for examplel2.c4r8.500is 4 vCPU, 8 GB RAM, and a 500 GB local NVMe disk. The local disk is fast but its lifetime is tied to the instance.
Service endpoints¶
| Service | Endpoint |
|---|---|
| Dashboard (Horizon) | https://dashboard.sunetvdc.se |
| Identity (Keystone) | https://identity.sunetvdc.se |
| Object storage (S3) | https://s3.orion.sunetvdc.se |
| Compute (Nova) | https://compute.orion.sunetvdc.se |
| Network (Neutron) | https://network.orion.sunetvdc.se |
| Block storage (Cinder) | https://volume.orion.sunetvdc.se |
| Image (Glance) | https://image.orion.sunetvdc.se |
| Orchestration (Heat) | https://orchestration.orion.sunetvdc.se |
You normally only need the identity endpoint or a clouds.yaml; the
client discovers the rest from the service catalogue.
Quotas¶
Each project has quotas for instances, vCPUs, RAM, volumes, storage capacity, floating IPs, and similar resources. When you hit a quota, creating new resources fails until you free some capacity or raise the limit. Customer administrators manage quotas from the project's Edit page in the Customer Portal.
Billing¶
Instances are billed per hour based on the flavor, volumes per GB per month by storage type, and object storage per GB per month. Windows images carry a per-vCPU license surcharge. See the official Sunet VDC price list for current figures.
