Performance and Reliability Patterns

Table 7.1 lists the patterns in the Performance and Reliability patterns cluster. The patterns are arranged so that later patterns build on earlier patterns. This implies a progression from more general patterns (such as Server Clustering) to more specific patterns (such as Failover Cluster).

Table 7.1: Performance and Reliability Patterns

Pattern	Problem
Server Clustering	How do you provide an infrastructure for your application that meets specific operational requirements, such as availability and scalability?
Load-Balanced Cluster	How should you design a scalable infrastructure tier that accounts for changes in load while maintaining an acceptable level of performance?
Failover Cluster	How should you design a highly available infrastructure tier that protects against loss of service due to the failure of a single server or the software that it hosts?
