2.3 Accounting Principles

All accounting of Pouta resources is done using Billing Units (BUs).

Academic research customers can have their resource use paid for by the Ministry of Education and Culture. For commercial customers or academic customers who require more than what is granted from the Ministry paid-for allocation, we have billing unit packages for purchase.

For more information about which category your project falls into, please visit the Accounts and Projects page.

Accounting of resources

Currently, we account for virtual machines, volume storage, and floating IPs.

We will also be accounting for object storage in the near future.

Resource Cost
Virtual machines See flavors page
Storage volumes 3,5 BU / TiB hour
Floating IPs 0,2 BU / hour


Please note that virtual machines consume BUs regardless you are using them or not. This means that a shut down or suspended virtual machine still consumes BUs. You can find more information about different states of virtual machine and their BU consumption on virtual machine lifecycle page . The minimum accounting time for a virtual machine is one hour.

Storage volumes consume billing units based on their size. The unit of measure is TebiByte hours.

Storage volumes consume BUs even if they are not attached to virtual machines.

Floating IPs are billed if they are allocated to the project or assigned to a virtual machine. Any extra routers you create, and connect to the external network, will also billed for one floating IP. The default router you get with the project does not consume billing units.

Other costs

If you have a contract with CSC, you will always be billed according to the contract if it differs from these practices. Commercial customers are usually also billed a fee for each member of the project.

Other quotas

In addition to accounting, projects have a quota for most resources they can use on Pouta. This defines for example how many CPU cores, how much memory you can use, or how many volumes you can have.

With the exception of the project users, projects are not billed based on their quotas. The quotas can be adjusted within reason based on your request.
