The pattern language continues to be relevant as of today, for instance in cloud application development and integration, and in the internet of things. In 2015, the two book authors reunited—for the first time since the publication of the book—for a retrospective and interview in IEEE Software .
Enterprise application integration is the process of linking such applications within a single organization together in order to simplify and automate business processes to the greatest extent possible, while at the same time avoiding having to make sweeping changes to the existing applications or data structures.
It is the basis of business process reengineering and the first step to achieving enterprise integration. Enterprise integration according to Vernadat is a rapidly developing technical field which has already shown proven solutions for system interconnection, electronic data interchange, product data exchange and distributed computing environments.
SOA is related to the idea of an API (application programming interface), an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API can be thought of as the service, and the SOA the architecture that allows the service to operate.
Business architecture; Process architecture; Information architecture; This is an approach to the coordinated sharing and exchange of information which is organized by models, which are describing common concepts and behavior. The pattern emphasizes a controlled sharing and exchange of information among autonomous components by communication ...
The ESB is implemented in software that operates between the business applications, and enables communication among them. Ideally, the ESB should be able to replace all direct contact with the applications on the bus, so that all communication takes place via the ESB.
A message broker is an architectural pattern for message validation, transformation, and routing. It mediates communication among applications [vague], minimizing the mutual awareness that applications should have of each other in order to be able to exchange messages, effectively implementing decoupling.

Applications architecture strategy involves ensuring the applications and the integration align with the growth strategy of the organization. If an organization is a manufacturing organization with fast growth plans through acquisitions, the applications architecture should be nimble enough to encompass inherited legacy systems as well as other large competing systems.
