Our verdict on Canonical MAAS
Canonical MAAS is an open-source infrastructure platform for discovering, commissioning, allocating, deploying, re-imaging, and releasing physical servers. It is aimed at infrastructure teams, data-center operators, DevOps engineers, and organizations managing server estates across data centers, private-cloud foundations, HPC, edge, and lab environments. Web, Linux, API, and self-hosted access support different operating models, while network-based provisioning handles standard and custom OS images across bare-metal machines.
The pricing structure separates the open-source software from paid support. Self-support is free for all machines. Essential costs $30 per managed machine per year and adds high availability support, role-based access control, and a knowledge base. Standard costs $50 per managed machine per year and adds a four-hour Severity 1 response SLA plus phone and ticket support during office hours. Advanced costs $100 per managed machine per year and provides a one-hour Severity 1 response SLA with phone and ticket support 24 hours a day, every day. The published plans are billed annually, and standalone support eligibility for controllers requires Ubuntu Pro.
MAAS stands out through the breadth of its physical infrastructure controls. It includes remote power control through server BMCs; DHCP, DNS, IPAM, VLAN, and subnet management; hardware inventory and commissioning tests; storage layouts such as LVM, RAID, bcache, VMFS, and custom layouts; deployment scripts before and after OS installation; and high-availability region and rack controllers. REST API and CLI automation connect it with Terraform, Juju, Ansible, OpenStack, and Kubernetes. Choose MAAS when bare-metal lifecycle automation and ecosystem integration are priorities. Teams seeking application-focused deployment or a narrower tool may prefer an alternative.
