Canonical’s solution was a third of the price of the other proposals we’d received. The solution is also proving to be highly cost-effective, both from CAPEX and OPEX perspectives.

More economical than Red Hat OpenStack Platform
By applying a per host pricing model to the subscription structure and offering design and delivery at a fixed price, Canonical's Charmed OpenStack is cheaper than Red Hat OpenStack Platform. Moreover, no license is required to get started with Charmed OpenStack. This means that organisations only have to pay for the environments that require enterprise support, such as the production environment, while they can run their testing and development environments free of charge.
More straightforward than Mirantis Cloud Platform
Instead of relying on random interconnected tools, Canonical leverages the concept of operators for OpenStack deployments, operations and upgrades. The OpenStack Charmed Operators (OpenStack Charms) enable model-driven architecture and abstract the entire OpenStack complexity. This results in a simpler OpenStack platform, fewer resources required to maintain it and reduced operational costs.
Open source unlike VMware
Canonical's Charmed OpenStack is fully open source which allows it to benefit from a broader community, faster development process and wider selection of technology choices than those available in VMware's platform. Choosing an open source platform avoids vendor lock-in and significantly reduces infrastructure costs.
