Apache CloudStack vs Cloud 66

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

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.
