Waldur
What Waldur is
Waldur is an open-source platform for managing private and public clouds and HPC centers. It automates OpenStack and Slurm and combines service publishing, self-service access, billing, reporting, and support ticketing. Organizations can list cloud services in its marketplace, while role-based controls let teams delegate resource management. Reports provide real-time, historical, and predictive views for service providers and consumers. Its accounting supports one-time, usage-based, and periodic billing, with links to third-party billing systems. Waldur connects with OpenNebula, OpenStack, and VMware vCenter; its OpenStack integration includes Keystone, Nova, Cinder, Glance, and Neutron. It is API-first and can be deployed on premises or in the cloud. Identity options include EduGAIN, LDAP, Active Directory, MyAccessID, Keycloak, SRAM via SCIM 2.0, SAML2, and Waldur user management. Service desk connections include Atlassian ServiceDesk, Zammad, and Microfocus SMAX. Waldur is free and co-developed by OpenNode and the University of Tartu.
