Canonical OpenStack vs Microsoft Azure Arc

Canonical OpenStack lets organizations run applications in their own data centers while giving teams self-service access to computing resources on demand. It is based on upstream OpenStack code and described by Canonical as 100% open source. Automation uses MAAS and Juju, spanning bare-metal provisioning through applications. Its architecture uses Kubernetes, OCI images, and snaps; Canonical says this decouples OpenStack from the underlying Ubuntu operating system. Canonical Ceph is included by default and supports up to 128 TB of data per node. The stack also includes an expandable Kubernetes layer, observability, Landscape system management, and MAAS bare-metal automation. Listed workloads include HPC and AI/ML, telco NFVI, sovereign clouds, local or regional public clouds, and edge infrastructure. Organizations can deploy the cloud themselves or have Canonical design, build, test, and validate it. The plan costs nothing, with no license or subscription charge; commercial support and consulting are separate. Support includes 24/7 phone and ticket coverage, with a stated one-hour response for Severity 1 issues. On-demand Kubernetes is currently in beta.
