Network Load Balancing and Server Clustering
Tridion Sites supports two different clustering methods: Network Load Balancing and Server Clustering.
- Network Load Balancing
- This clustering method only clusters the network layer. Either Windows or a hardware load balancer can be in charge of balancing the network requests between the clustered servers. Load balancing is useful when performance and scalability is needed in IIS.
- Server Clustering
- This clustering method makes multiple machines act as a single machine, sharing disk space and providing fail-over support, to create a fault-tolerant system.
Refer to the following online documentation resource from Microsoft, which explains how to set up these clusters: https://docs.microsoft.com/en-us/windows-server/failover-clustering/failover-clustering-overview.
