Segmenting the workload
This technique applies to the Web presentation server, the Web application server, the data server, the intranet firewall, and the network. The goal is to split up the workload into manageable chunks, thereby obtaining a more consistent and predictable response time. The technique also makes it easier to manage which servers the workload is being placed on. Combining segmentation with replication often offers the added benefit of an easy mechanism to redistribute work and scale selectively, as business needs dictate.
An issue with this technique is that, in order to implement the segmentation, the different workloads serviced by the component need to be characterized. After segmenting the workload, additional infrastructure is required to balance physical workload among the segments.
