OpenStack is an open-source cloud computing platform. It is mostly known for its basic core IaaS components: compute, storage, network and images. Although other components are also available under the OpenStack umbrella (e.g. the Swift module for object storage, or Manila for shared file systems), they are not often part of OpenStack deployments.

Galaxy Europe, where I work as SRE, runs on bwCloud (one of de.NBI cloud's locations), that is managed with OpenStack. I work with of OpenStack daily, and interact with it via web dashboard, cli, Python API and Terraform.
