Failover Clustering for High Availability
AggreGate has internal support for building a failover cluster to ensure high availability of provided services. The failover cluster consists of two or more installations of AggreGate Server and one or more installations of the underlying database engine.
The failover cluster's objective is reaching almost 100% availability of the server. The cluster consists of Master Node and one or more Failover Nodes. During normal operation, the master node is servicing all operations. All failover nodes are running in standby mode and monitoring the state of master node.
The failover nodes are automatically switched to Failover Master mode (i.e. activated) in the following cases:
