Unifying Node Rules

The endpoints of an application pattern instance might be shared by other entities. Unification allows you to
identify all entities that share a resource as a single application pattern instance.
To help identify all similar instances that share the same components, you can specify a node‐based rule as a
unification rule. When the rule is applied, it results in one instance being detected, instead of several that
contain all the same components.
For example, you might not know how many ADM Collector components exist in an instance of an ADM
application. You could end up with multiple instances instead of just one, as shown in Figure 6‐5.

When you specify a node rule as a unification rule, the application pattern definition unites all
aggregator‐collector instances that share the same ADM aggregator into one instance as shown in Figure 6‐6.
