Cloud Failover Plug-in

The Exasol cloud failover plug-in is pre-installed in the Exasol 7.1 cloud offerings. This plug-in enables the cold standby feature for your cloud instance (for more information, see Fail Safety (Cloud)). To enable the cold standby feature you must 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 must 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 does not 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.
