Registration

In a Nutshell

Access to bwCloud-OS requires an active account from a bwIDM-participating institution. Your account must include a valid entitlement, assigned by your home institution. This is usually automatic. If it is missing (see here), contact your institution’s IT support. The bwCloud-OS team cannot assign entitlements. Log in once to the Dashboard to activate your profile. Setup is automated via bwIDM. After login, select your region as described here to begin using bwCloud-OS.

Registration requirements

Under Conditions of use are the requirements defined that are checked by bwIDM before the registration is triggered.

Automated resource provisioning

During the registration on bwIDM for the bwCloud-OS service, the following steps are streamedlined:

1. A user registers himself*herself.
2. bwIDM requests the creation of a user account by the bwCloud-OS and forwards a set of user data.
3. The bwCloud-OS parses the user data, including given entitlements.
4. Based on these data, a user account and a start project is created. The quota flavor given in the entitlement defines the project quota. If more than one quota eligibilities are given, a random one is chosen. The eligibility can later on be changed.

FAQ

What is "bwIDM" and why does it know me?

Every member of a higher education institution in Baden-Württemberg (university, college, PH, HAW, etc.) has a personal account for accessing the IT services provided by their institution. If the institution participates in the federated identity management system bwIDM, its members can also apply for additional IT services offered by other participating institutions.

To allow external IT services to identify users, certain personal data is transmitted via bwIDM to these services during registration and use of the service. Federated identity management ensures, through a model of mutual trust, that the external service can verify the user’s affiliation with their institution — confirming that the account is valid and the user is officially recognized. Within the bwIDM Federation, participating institutions have agreed on a minimum set of personal data that is transmitted to external IT services. This includes standard attributes such as eduPersonPrincipalName, mail, givenName or eduPersonEntitlement.

What does "region" mean in bwCloud-OS?

In bwCloud-OS, a region refers to one of the four operating sites: Freiburg, Karlsruhe, Mannheim, and Ulm. Each region runs its own infrastructure but is accessible through a shared interface (Dashboard).

Resources such as virtual machines (VMs, instances), networks, and storage are bound to the region in which they are created. For example, an instance launched in the Mannheim region will receive an IP address from Mannheim’s specific IP range(s) — this address cannot be transferred to another region.

You can switch between regions in the Dashboard interface as described here.

What is my "home region"?

In bwCloud-OS, each user is initially assigned a home region during account setup. For users from one of the four operating sites (Freiburg, Karlsruhe, Mannheim, Ulm), this assignment is straightforward. For users from other institutions, the assignment is based on the network topology of BelWue — aiming to route each user to the nearest operating site for optimal connectivity. However, you can apply for a project with resources (also) in other regions.

A table showing the current home region assignments can be found here.

Where do I select the region in the Dashboard?

You can select a region from the drop-down menu located on the left side of the top navigation bar in the Dashboard. The currently active region is marked with a checkmark. Simply click on a different region in the list to switch to it.
