The adoption of Aspect Oriented Programming paradigm in enterprise software is rapid. It is interesting to look at various applications of AOP in enterprise architecture:

• Apply design patterns as modules
• Application security architecture
• Transaction, Logging, Stats, etc.
• Enforce architectural design standard for application development by leveraging AOP tool support
• JVM Clustering

AOP allows modularization of application and provides manageability and loose coupling from a software architecture perspective. From a product perspective, it allows to easily plug in features by allowing various implementation of aspects to be plugged-in quite easily.
