Cloud Failover Plug-in
Exasol's cloud offerings come pre-installed with Exasol's cloud failover plug-in. The plug-in enables the cold standby feature for your cloud instance (for more information, see Cold Standby). To enable the cold standby feature, you need to add a standby node to your system during the installation (while configuring the template parameters on respective cloud console). When the installation is completed, you need to shut down the standby node.
When a node fails, the cloud failover plug-in initiates a system restart to bring the system online. If the system doesn't come back online, the cloud plugin looks for the stand by node and starts it. Once the standby node is online, it takes over for the failed node.
