Remember this Failover clusters are one method of server redundancy and they provide high availability for servers. They can remove a server as a single point of failure. Load balancing increases the overall processing power of a service by sharing the load among multiple servers. Configurations can be active-passive, or active-active. Scheduling methods include round-robin and source IP address affinity. Source IP address affinity scheduling ensures clients are redirected to the same server for an entire session.
