Best High Availability Cluster Solutions

OpenMetal provides the infrastructure foundation for high availability deployments, combining hosted private cloud on OpenStack, Ceph distributed storage, and dedicated bare metal servers across multiple geographic locations. Ceph delivers built-in fault tolerance with self-healing capabilities and automatic recovery from node and disk failures. OpenStack provides the orchestration layer for automated failover, redundant networking, and consistent multi-site deployments. For teams building toward four or five nines availability, OpenMetal removes two common barriers: the egress fees that make cross-region replication expensive on public cloud, and the lack of root access that limits custom disaster recovery configurations. Full platform access lets you tune replication and failover to match your actual requirements.

Deploy a reliable, performant, and feature-packed cloud server, available in Canada (Toronto and Montreal) and France (Roubaix). KVM cloud servers on redundant SSD disk arrays. Check out our pricing! Take live snapshots of your VM at any time to extract its current disk state for backups or cloning, without any downtime. Volumes are detachable disks stored on our high-availability cluster. Attach volumes to VMs for extra space, or provision VMs with a volume as the boot device. Automatically configure your VM during the boot process with bash and cloud-init startup scripts. Security groups allow you to define traffic restrictions on groups of virtual machines at the infrastructure level. Your VMs get their own private, isolated internal network, on which they can securely communicate. VMs can burst above their baseline performance for short periods to utilize additional CPU and I/O resources, making load spikes easier on your application.
