Dynamic Site Servers (DSS) do not NEED to be clustered. Replication can be used effectively.
If User Generated Content (UGC) is not a requirement, there is no reason to cluster
Or any other type of update where the nodes need to be synchronised
Clustering can be an overhead with no benefit
When does clustering become a disadvantage?
Traffic between nodes
Time to updates nodes exceeds slows the response time
Threshold – exceeded
What is that number?
Dependant on application
Write intensive activity
Approximately 3 nodes – load dependant
