What Waldur is
Waldur is an open-source platform for managing private and public clouds and HPC centers, with automation for OpenStack and Slurm, billing, self-service, and a support desk. Organizations can publish cloud services through its marketplace, while users access a self-service portal with social, national, or federated identity providers. Reports cover real-time, historical, and predictive information for service providers and consumers. Built-in accounting handles one-time, usage-based, and periodic billing, with links to third-party billing systems. Role-based access controls let teams delegate resource management; trackable events, alerts, and notifications support activity monitoring. Waldur integrates with OpenNebula, OpenStack, and VMware vCenter, including OpenStack Keystone, Nova, Cinder, Glance, and Neutron. It is API-first and can be deployed on premises or in the cloud. Other listed integrations include Azure, AWS, DigitalOcean, identity systems, and service desks. Professional software support is available for self-hosted installations, and training can be delivered on-site or remotely. Waldur is presented for public-sector, research, and enterprise uses.
