Network Load Balancing and Server Clustering
SDL Tridion Sites supports 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 method makes multiple machines act as a single machine, sharing disk space and providing fail-over support, to create a fault-tolerant system.
Microsoft's online documentation resources explain how to set up these clusters:
- For Windows Server 2016, consult https://docs.microsoft.com/en-us/windows-server/failover-clustering/failover-clustering-overview.
- For Windows Server 2012 R2 with Update, consult https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831579(v=ws.11).
