Canonical OpenStack vs Cloud 66

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.

Cloud 66 deploys and manages applications on cloud infrastructure customers provide, including major providers, hybrid environments, and their own servers. It supports Rails or Sinatra apps, Docker containers on Kubernetes, and static sites built with Jekyll, Hugo, or Gatsby. Deployment options include zero-downtime, blue/green, and canary deployments, plus previews for branches, tags, and pull requests. Hosted Docker build servers and autoscaling based on CPU, memory, queue backlog, and Nginx response time are available. Managed databases can include off-site backups, replication, and monitoring; the platform also provides server monitoring, alerts, logs, and metrics. Listed cloud providers include AWS, DigitalOcean, Google Compute Engine, Hetzner Cloud, Latitude.sh, Linode, OVHcloud, Microsoft Azure, and Vultr. Cloud 66 says it does not store customer code or data on its servers. Customers pay their cloud provider directly for server costs. The Free plan is free for up to one server, one static site, and five deployments per 24 hours. Developer is $23 a month and supports up to two servers and two static sites.
