Network Load Balancing and Server Clustering
SDL Web 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 2008 R2, consult http://www.microsoft.com/windowsserver2008/en/us/failover-clustering-technical.aspx.
- For Windows Server 2012, consult http://technet.microsoft.com/en-us/library/hh831579.aspx.
