Sunbeam OpenStack Disaster Recovery Using Masakari and Consul

Learn how to implement automated disaster recovery in Sunbeam OpenStack environments using the Masakari high availability framework integrated with Consul-based detection mechanisms. Discover the architecture that combines Consul clients on compute nodes to monitor management, tenant, and storage network interfaces through TCP health checks, reporting connectivity status to a Consul server running on the Kubernetes control plane. Understand how the openstack-hypervisor daemon responds to detected failures by disabling nova-compute services and shutting down affected VMs to prepare nodes for evacuation. Explore how Masakari's HostMonitor component polls Consul to trigger automated evacuation workflows that migrate workloads from failed hosts to healthy ones. Master the integration of Masakari's evacuation capabilities with Consul's gossip protocol and dynamic recovery mechanisms to deliver robust high availability solutions for large-scale private cloud deployments using MAAS (Metal as a Service), enhancing overall system resiliency through automated VM evacuation during host failures.
