Accounting Principles and Quotas

This document describes how resource usage in Pouta is calculated as 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, object storage and floating IPs.

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. Another source for estimating usage is the Resource Calculator

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.

Objects storage consumes billing units based on the stored data amounts. The billing units are consumed until the data is removed.

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.


Each cPouta and ePouta project have a cloud computing quota that limits the use of simultaneous cloud resources. There is a default cPouta project quota which is quite small, but users can apply for extensions through the resource allocation process of CSC.

Default size of the cPouta project quota.

Resource type default
Instances 8
Cores 8
Memory 32 GB
Floating IPs 2
Storage 1 TB

With the default resources, a cPouta user could launch 8 standard.tiny instances or 2 standard.large instances or 1 hpc-gen1.8core instance. The purpose of the quota is to prevent individual users from reserving the entire cluster and thus preventing access for other users.

Storage is also limited by a quota. The default quota for new projects is 1 TB. Additional allocations can be requested through our resource allocation process.

The initial quotas for ePouta projects are agreed on when starting a new project.

Please note that having free quota does not guarantee that specific resources are available.

Specific virtual machine flavors may be full, so you can not provision them even if you have the quota to do so. We always strive to have free computing resources in some flavors. We will be improving the visibility of what flavors are available in the future.

We try to always have free storage and floating IP resources, if quota for them has been allocated.
