With organizations running increasing numbers of critical systems over private clouds, there is a greater need than ever for reliable, highly available infrastructure. VM high availability allows for maximum uptime when running in the cloud, while shielding the user from any unplanned downtime of the infrastructure.
In broad terms, both Cloud Native apps and traditional applications rely on high availability to maintain maximum uptime. However, while Cloud Native apps are designed to tolerate failures of an availability zone by auto scaling to another server within the zone, traditional apps cannot tolerate such infrastructure failures, as they assume that the underlying infrastructure is fully functioning. OpenStack Masakari provides VM high availability to these apps by automatically recovering VMs from compute host failure events.
