Workload management
The proposed configurations should ensure that each machine or server in the configuration processes a fair share of the overall client load that is being processed by the system as a whole. In other words, it is not efficient to have one machine overloaded while another machine is mostly idle. If all machines have roughly the same power, each should process a roughly equal share of the load. Otherwise the workload should be based on weights associated with each machines processing power assuming no affinity configuration.
Furthermore, if the total load changes over time, the system should automatically adapt itself, for example, all machines may use 50% of their capacity, or all machines may use 100% of their capacity. But not one uses 100% of its capacity and rest uses 15% of their capacity.
In this redbook, we discuss Web server load balancing using both WebSphere Edge Components and WebSphere workload management techniques.
