Which type of cluster automatically switches to a backup node in case of…

Concept

A cluster combines multiple computers so they can provide a service or computing resource together. Cluster types are distinguished by their main design goal, such as service continuity, pooled computation, shared storage, or workload distribution.

Application

The stem describes automatic transfer to a backup node after a failure. That behavior is failover: a health-monitoring mechanism detects that the active node is unavailable and moves or restarts the service on a standby node.

Contrast

• High Availability Cluster: emphasizes service continuity through redundant nodes and failover.

• Grid Cluster: pools distributed computing resources to execute large or divisible workloads.

• Storage Cluster: combines storage nodes for shared capacity, data access, and storage redundancy.

• Load Balancing Cluster: spreads incoming requests or jobs across active nodes to improve throughput and utilization.

Cross-check

Follow the failure sequence: the active node stops responding, monitoring detects the failure, and the service is transferred to a standby node. This sequence directly matches the availability-and-failover objective.

Therefore, the cluster type is High Availability Cluster.
