The Evolution Of Enterprise Application Integration

System and application integration is becoming increasingly important in today’s organizational infrastructure. A vast range of Enterprise Application Integration approaches and ideas have been put forth to achieve this goal. Researching application and data integration solutions can be overwhelming when you’re just getting started because there are so many acronyms, viewpoints, and jargon to wade through.

Understanding Enterprise Application Integration


Enterprise application integration is the continual process of integrating two or more disparate systems, whether hardware or software. Different financial programs may be able to interface and process data or transactions more effectively with this integration.

The process of synchronizing or aligning the numerous systems and databases utilized by a company, network, or industry is also known as enterprise app integration.

A wide range of technology, tools, and services are often engaged in this procedure. The complexity of this procedure varies based on the number, size, and sophistication of the systems involved and their interoperability. Computer languages and architectural frameworks can vary widely between the systems involved. Systems that have been around for a long time, such as extensively customized ones, may be more challenging to implement.

The Origins Of EAI

Enterprise Application Integration, or EAI, has been around as a technical term since the early 2000s, but the underlying problem that it aims to answer is far more established. Overall, Enterprise Application Integration can be seen as a collection of ways to make different systems in a typical business infrastructure more interoperable.

Many different systems and apps make up an enterprise architecture, which is why it’s so common. These systems and applications supply the numerous services a firm needs to function. To manage their supply chain, customer relationships, personnel data, and business logic, a single corporation may use several systems, either built in-house or licensed from a third-party vendor. In many cases, this modularization is a good thing.

There are several benefits to decomposing the process of running an enterprise into a series of minor functionality, such as making it easier to implement and adapt to the latest technological advances in each sector.

However, to reap the benefits of a distributed, modular system, an organization must incorporate solutions that address the architecture’s inherent issues:

  • To ensure interoperability, separate infrastructure components must use the same operating system and data formats and languages.
  • For a modular, distributed system to function correctly, a consistent technique of controlling data movement across applications and systems is essential to enforce consistency throughout the database.
  • Solutions for modular infrastructure integration need to be highly stable and flexible because they are the glue that holds everything together.

When Point-To-Point Integration Isn’t Good Enough

Before EAI-type technologies were developed, point-to-point integration generally dealt with integration issues. Connector components are designed for each pair of applications or systems to communicate in a point-to-point architecture. Data transformation, integration, and any other messaging services required between only the unique team of components it is designed to integrate are all handled by this connector.

This model works effectively if you need to integrate two or three systems into your infrastructure. It provides an easy-to-use integration solution tailored to your infrastructure’s needs. Because of this, the number of points of connection necessary for a particular integration design grows exponentially as more components are added to an infrastructure.

To be deemed wholly integrated, a three-component infrastructure requires three point-to-point connections. In comparison, the inclusion of two more components brings the total number of connectors up to ten. Point-to-point integration is no longer an option when the infrastructure contains 8 or 9 components, and the number of connections exceeds 30. This is already nearing an unacceptable degree of complexity.

For complicated enterprise scenarios, a point-to-point connection is unsuitable since it requires the development and maintenance of individual connectors for each of the systems involved (or, in some instances, the purchase of expensive connectors from a vendor).

The EAI Approach to Integration

EAI solutions use various forms of middleware to centralize and standardize integration procedures across a whole infrastructure to avoid the complexity and fallibility of integrating complex infrastructures using a point-to-point method.

The components of an EAI-based infrastructure use standard means of connection to a shared system that is responsible for providing integration, message brokering, and dependability functions to the entire network, rather than requiring a different connector for each application.

As a result, integrating modular systems is no more a maze of tangled wires and brittle connections but rather a straightforward operation for the system itself. Data transformation engines, modular integration engines, and other components are all included in EAI systems to provide a single integration solution.

Basically, EAI integrates business applications, databases, and workflows to ensure consistent use of information. So, if one application changes to the core business data, they are correctly reflected in all other applications.

In A Nutshell:

In other words, Enterprise Application Integration (EAI) translates data and commands from one application format to another. The process of integrating two disparate systems, be they hardware or software, is known as enterprise application integration. Information sharing, data exchange, and resource coordination are all made possible through enterprise application integration (EAI).

At least some companies are still using obsolete legacy systems, which their original manufacturers may not even support. As a result, the procedure may become more complicated and time-consuming due to the additional hands-on labor required by specialists.
