Projects and Quota

In a Nutshell

Each bwCloud-OS project has predefined quotas for vCPU, RAM, storage, and networks. Quota increases can be requested via the bwSupportPortal. Group projects allow shared access to resources. Members can manage instances collaboratively. Quotas can be assigned in multiple regions. A designated project owner is required to manage membership and act as the main contact. Instances cannot be moved between projects directly. Use snapshots and volume transfer instead, as described here.

Projects

How can I switch between projects?

A user can be a member of multiple projects, and projects can have quota in multiple bwCloud-OS regions.

To switch between projects and regions, use the project/region selector button located at the top left of the Dashboard. This allows you to choose the target project and corresponding region for your current session.

Can I move an instance to another project?

Instances cannot be directly moved between projects. However, you can use the following workaround, provided the target project has sufficient available quota:

In the Source Project:

1. Create a snapshot of the instance. The snapshot will appear under Images.
2. From the snapshot, create a volume. The volume will appear under Volumes.
3. Create a transfer for the volume and record the Transfer ID and Authorization Key.

In the Target Project:

1. Go to Volumes and select Accept Transfer.
2. Enter the recorded Transfer ID and Authorization Key. The volume will now appear under Volumes.
3. Convert or upload the volume to an image. The image will appear under Images. This process may take some time.
4. Launch a new instance from the image in the target project.

Group Projects

In which situations is a group project useful?

Group projects allow multiple users to share and jointly manage resources within a single bwCloud-OS project. This is particularly useful for:

• Collaborative administration of servers with a long-term or operational purpose
• Teaching or training scenarios, where students or participants need to collaborate
• Projects that involve users from multiple bwCloud-OS regions

Such collaboration is also supported through the use of access tokens (Application Credentials).

• Note: If the only goal is to allow multiple users to connect to the same virtual machine, you can simply add their SSH public keys to the ~/.ssh/authorized_keys file on the VM. In that case, a group project is not required.

What does resource administration look like in a group project?

OpenStack uses a very simple role and rights model:

• There is the role of “Administrator”, which is reserved exclusively for members of the bwCloud-OS operations team.
• All regular users — including those in group projects — have the same standard user permissions.

This means that a group project functions the same as a personal project, with one key difference: multiple users are assigned to the same project.

As a result:

• Every group member can see all shared resources (instances, images, security groups, etc.).
• All members can create, modify, or delete resources.
• There are no internal role distinctions within a project — all members have equal rights.

How can I request a group project?

To create a group project, you need to submit a support ticket with specific information about your request. Please note:

• Only users who are already registered in bwCloud-OS can be added as project members.
• The project must have a designated owner. Please review the role of the project owner, who is responsible for managing the project and its quota usage.
• The project name should be no longer than 16 characters.

Please use the following template when submitting your request:

SUBJECT:        NEW_PROJECT
MOTIVATION:     TEXT
REGION:         NAME
PROJECT_NAME:   NAME 
OWNER_UUID:     UUID
MEMBER_UUIDS:   UUID, UUID, ...
NUMBER_VM:      INTEGER
RAM_GB:         INTEGER
VCPU:           INTEGER
STORAGE_GB:     INTEGER
SPECIAL_QUOTA:  TEXT
CUT_OFF_DATE:   dd.mm.yyyy

Notes

• Members of the University of Stuttgart are subject to special rules, which are explained in detail here.

Why is it necessary to specify a group project owner?

The person designated as the project owner is needed for several important reasons:

1. Billing and accountability: If cost allocation is introduced in the future, any billing or formal communication related to the group project will be directed to the project owner's institution or department. (Note: The owner can be changed later if needed.)
2. Primary contact for the bwCloud-OS team: The project owner acts as the main contact person for the bwCloud-OS team — for operational issues, incidents, and support inquiries.
3. User and membership management: The owner is responsible for managing group membership. We can only accept requests to add or remove members from the owner (or a designated replacement), since all group members have the same technical permissions. Otherwise, we cannot verify who has the authority to manage membership.

Can the project owner be a functional or shared account?

No. All accounts and identifiers used in bwCloud-OS — including those for project owners and project members — must be assigned to individual, identifiable persons.

Group projects are not an exception to this rule. The same identity and accountability requirements apply as for personal projects.

Can group members be changed?

Yes, members of a group project can be added or removed at any time.

Only the project owner is authorized to request changes to the group membership.

To request member changes, please submit a support ticket and provide the following information using this template:

SUBJECT:         MEMBER_PROJECT
NEW_OWNER:       UUID
PROJECT:         UUID
MEMBERS_ADD:     UUID, UUID, ...
MEMBERS_REMOVE:  UUID, UUID, ...

Project Quota

Quota defines the resource limits allocated to a project, such as vCPUs, RAM, networks, and storage. Quotas differ depending on the type of project:

• Private user projects receive initial quotas based on the region and the user's assigned entitlements.
• Group projects allow multiple users to share and flexibly manage the allocated quotas collectively.

How can I request additional quota?

To request additional quota, please provide the following information and submit your request via the Support Portal using the following template:

SUBJECT:        NEW_QUOTA
MOTIVATION:     TEXT
USER_UUID:      UUID
PROJECT_UUID:   UUID 
NUMBER_VM:      INTEGER
RAM_GB:         INTEGER
VCPU:           INTEGER
STORAGE_GB:     INTEGER
SPECIAL_QUOTA:  TEXT
CUT_OFF_DATE:   dd.mm.yyyy

Notes

• The values you provide must represent the total desired quota for your project after the increase, not the additional amount to be added on top of your current quota.
