Businesses face challenging task in integrating their mission critical enterprise applications. Enterprise Application Integration (EAI) forms a middleware leveraging various technologies and services to integrate applications in an enterprise. EAI links applications within the same organization and automates business processes either at the backend or frontend.

Organizations strive to attain integration of the real time processes between its disparate applications thereby allowing end-to-end automation. Enterprise applications typically comprise of legacy applications and databases which they want to leverage at the same time needs to add or migrate to latest technologies that possibly fit. Enterprise architectures rely on many systems and applications for various services such as Supply Chain, CRM, Employee Information, Business Information, etc. to run their day-to-day business.To utilize the benefits of distributed and modular systems, organizations must adapt newer technologies to deal with the issues such as interoperability, data integration, stability, robustness and scalability.

Devising point-to-point integration model that uses tightly coupled connections is not good enough to satisfy all the requirements for a smooth integration. In point-to-point integration model, each pair of applications or systems communicate using the unique connector component that handles data transformation, integration and other services. However, this model doesn’t scale to large architectures as the number of point-to-point connections increase exponentially thereby shooting up the complexity.

EAI provides standard integration solutions using various middleware and a centralized model. EAI based infrastructure connects to a common system that manages integration and uses a standard method to connect. It allows application to send message irrespective of consumer’s location or data requirements. EAI brings flexibility to the architecture by allowing addition or removal of new parts by simply altering the configuration of the EAI provider. Modern EAI approaches provide data integration and other functionalities such as scalability, security, network administration, etc.

Traditional EAI used central hubs called brokers to incorporate all integration related functionalities. The Broker EAI model uses a central integration engine for communication and can become a single point of failure. Broker Model uses proprietary products and are heavy weight, these disadvantages lead for suggestion of the bus architecture ESB (Enterprise Service Bus) as the new approach to EAI.

ESB approach for EAI provides light weight, tailor-made solution with added functionalities such as Error handling, Security Transaction processing, etc. ESB approach provides the following advantages:
  • Light weight
  • Location Transparency
  • Easily expandable
  • Better Scalability
  • Service Oriented Architecture

Before choosing an EAI service for your organization, you should be clear with your requirements such as number of applications to be integrated, scalability of the solution for future needs, communication protocols, etc.
