To simplify the explanation of the Application and Logical Datacenter diagrams we intentionally left out one of their most important features, Settings and Constraints. This is better understood from the context of the Deployment Diagram. When you have your applications inside your servers, as shown in Figure 54-5, you can choose to validate the diagram (after right-clicking the design surface). This will ensure that all the settings in the Application Design match constraints in the Logical Datacenter Design, and that settings in the LDD match constraints in the AD.

To specify settings and constraints from View Other Windows Settings and Constraints, you can open the editor. Then, by selecting an application, endpoint, server, or zone, you can specify its settings and constraints.

If this were actually happening, ...
