Scaling Web Services

Chapter 19, “Application Scalability,” examines in detail ways to scale cloud-based applications. Depending on its program demands, a web service may become a potential system bottleneck. An easy first solution is to scale up the web service by placing it on a faster server. If high utilization of the service continues, the developers may need to distribute copies of the web service onto additional servers and then use a load balancer, as shown in FIGURE 11.3 to distribute the program requests.
