Deployment Infrastructure Example

An example of an Application Center cluster deployment infrastructure is illustrated in Figure 4.2. As you can see, each Application Center cluster is in its own Windows domain. As an additional management and security measure, you could also establish organizational units within each domain. By positioning these clusters between the two firewalls that demarcate the demilitarized zone (DMZ), you can create a highly secure cluster environment.

The infrastructure illustrated in Figure 4.2 is only meant to serve as a starting point for designing and implementing a robust and secure cluster topology. Your business needs will dictate the requirements for back-end database servers or clusters, component servers or clusters, and multi-level testing/staging configurations.
