Clustering is a technique that allows you to get more out of your existing infrastructure. With clustering, two or more servers form a single logical entity. With clustering, two database servers act as one logical entity..
A cluster can be active-active, in which case it is distributed across two nodes. With an active-passive cluster, all resources are located on a single node, with a second node as a solution in case the active node should fail.
We offer clustering as a failover solution, in order to guarantee high availability of data and applications. That type of clustering is based on the use of redundant nodes.
If a problem occurs on one node, the second one immediately takes over, so the service does not get interrupted. Besides traditional types of clustering based on two nodes, we also have extensive expertise with multi-node clustering, where we can manage up to three or four database nodes per cluster.
