These are the available clustering node configurations
1. Active/Active – Traffic is directed to another existing node or balanced across all other nodes
2. Active/Passive – A complete new node is served when primary node fails
3. N+1 – Serving a complete new node in the place of primary node and the new node in the cluster must be capable of handling any services which the primary node handled with/without any special additional software.
4. N+M – Here more than one dedicated nodes are served for handling failovers.
This may require high cost and maintenance.
5. N-to-1 – Here the backup node is serving temporarily until the primary node is brought back online. Then the running services are transferred to primary node.
6. N-to-N — A combination of Active/Active and N+M clusters, N to N clusters.
