Overview

ZStack Cloud provides high availability (HA) for double management nodes (MNs, also known as hosts) by using separate HA suites. When any one of the MNs is disconnected, the HA will be triggered in seconds to ensure the business continuity.

HA Mechanism

In a dual-MN model, each MN runs a zsha2 HA process. This process monitors the critical services, including the MN service, UI service, and database service, on each MN in real time. When any critical service is down, the Cloud immediately triggers virtual IP (VIP) migration through Keepalived, and then attempts to restore the downtime service.
