What is Enterprise Application Integration?

Enterprise Application Integration (EAI) is a strategic approach to connect and unify diverse disparate software systems and applications within an organization. It enables data, resources, and processes to be consolidated and share across different applications. This helps you seamlessly connect various on-premises & cloud apps to transform & utilize data for smooth workflows.

It is over a common platform and requires data integration in the back end for the smooth functioning of the connected applications. Further, EAI helps streamline processes like billing, marketing, accounting, and customer relationship management with increased data availability. It helps establish a middleware framework that enables free data flow between applications without significantly changing the database configurations or the applications themselves.

Now that you know that EAI connects disparate applications to enable a seamless flow of data, let’s explore the multiple benefits it delivers to your organization.

Advantages of Enterprise Application Integration

Enterprise Application Integration Benefits

Enterprise application integration offers several significant advantages for enterprises and organizations of all sizes. By integrating different software systems, EAI can help improve information sharing, streamline business processes, reduce IT complexity, and increase agility.

Are you wondering how EAI technologies can simplify all critical concerns? Read this if you wish to get a clear insight into the business benefits of EAI.

Enterprise Application Integration Models

As there is no one-size-fits-all approach for integration, there are various models that help establish a connection between different applications. We’ll explore five essential types of enterprise application integration models that you should be aware of.

1. Point-to-Point Integration

It handles simple interactions between two data sources.

  • As part of this approach, a script pulls, translates & transfers information from one application to another.
  • Proves to be effective with relatively small operations and become inefficient while handling several systems all at once.

2. Hub-and-Spoke Integration

As the name suggests, this model uses a central “hub” where applications and systems connect via “spokes.”

  • The information is reformatted and distributed from one central database, thus eliminating the need to interconnect subsystems.
  • Yet the development team would still have to engage components that would automatically set the route information to the appropriate destination.

3. Bus Integration

An advanced method of the hub-and-spoke model, it performs the same tasks but in a different architecture.

  • It runs without human interference, using a defined set of standards that govern data flow between applications.
  • It enables data transmittance and retrieval as the rules of each service.

4. Middleware

This software routes traffic between application interfaces and operating systems to translate & support communication. It simplifies data aggregation across systems using different scripts and formats.

5. Microservices

This is the standardized architecture for modern cloud-based enterprise applications. Organizations that use web-based integration can collect big data through internal and external sources with the help of application programming interfaces (APIs).

Enterprise Application Integration Strategy

An enterprise application integration (EAI) strategy is a plan for connecting and integrating the various software applications used by an organization. It allows businesses to share data and automate system processes. EAI strategy can help businesses improve their operations, make better decisions, and be more agile. Let us help you understand the comprehensive overview of these strategies below.

Batch Data Integration

Irrespective of whether applications are used for internal or external-facing software, enterprise application integration helps synchronize all databases, thus allowing complete data access throughout a business. Herein, an application reads information from another app or software and begins the integration process. With data transfer, a relationship needs to be established between various elements like file format, location, standards, privileges & more, which should be created beforehand between both parts.

Shared Database

Most organizations have individual databases that help teams carry out daily activities. However, since many people have access to it, there are chances of duplication and redundant storage of information. With the right application integration strategy, you can centralize all the information in a single repository that can be used multiple times and yet avoid duplication & buildup of unnecessary information.

Remote Procedure Invocation (RMI)

This takes place when an application exposes its function through an interface that acts as a layer to manage complex datasets. It enables transparency, asynchronous communication and scalability to boost efficiency. With a robust and defined interface, other applications can make use of it.

Messaging Strategy

With a messaging integration strategy, various applications within an organization stay connected through a messaging bus. The bus helps with the exchange of information, functions, and data, thus creating a seamless flow of communication.


The ESB infrastructure and the architectural model powered by the SOA technology are the most preferred methods of integration by organizations.

How To Implement Enterprise Application Integration?

The EAI implementation plan provides a step-by-step guide to developing and deploying a successful EAI solution for your organization.

EAI implementation plan

Step 1: Assess Your Integration Needs

Start by conducting a comprehensive assessment of your enterprise application integration requirements. It requires identifying the applications and systems that need integration, determining the data to be shared, and optimizing business processes. Some key factors to consider include your current IT infrastructure, business objectives, and available resources. Gain a clear understanding of your integration needs to guide the subsequent steps.

Step 2: Choose an Architecture Model

After identifying your integration requirements, the next step involves selecting an appropriate architecture model for your enterprise application integration system. There are three main options:

  • Point-to-Point Integration: This straightforward approach involves direct connections between individual applications. While simple, it can be challenging to maintain and expand as your organization grows.
  • Enterprise Service Bus (ESB) Integration: An ESB acts as a central hub enabling communication between numerous applications. While this architecture offers scalability and manageability, its implementation can be intricate and involve higher costs.
  • Hybrid Integration: This model combines point-to-point and ESB integration, making it suitable for organizations with diverse application and system integration needs. It integrates cloud-based services and on-premises systems and applications of your organizations to work as a connected unit.

Step 3: Choose Your Integration Tech Stack

Once you’ve settled on an architecture model, identify the specific integration technologies you’ll employ. This includes selecting EAI software, hardware, and networking infrastructure. When choosing EAI software, consider factors such as:

  • Features: Ensure the software supports your chosen integration architecture, data formats, and messaging protocols.

Enterprise Application Integration Best Practices

Enterprise Application Integration (EAI) is the key to seamless data exchange in modern business. Yet, EAI comes with its challenges. You must, therefore, follow a set of best practices to ensure a successful integration process. Here are some practical best practices that will help you simplify your business operations and provide an ideal path to a more integrated and agile enterprise.

Devise the Right Integration Plan

Laying down a solid enterprise application integration strategy is a must, and an expert EAI team can help you layout the plan. Keeping the end goal in mind is a must and here are four ways to overcome deployment issues:

  • Monitoring – The primary components included in enterprise software must be enabled for real-time monitoring. By analyzing how your current systems are performing, instrumentation helps with clear identification of CPU utilization, system and memory utilization, or open resource connections. This information provides the development team and administrators with the support they need to design and implement an integration architecture that can streamline and operate the system at optimal performance.
  • Accountability – Apart from the initial support and installation, updates for integration rules and components like adapters may need regular activity. The components and regular updates ensure the continuity of operations.
  • Service Level Agreements – The SLA is offered before installation and underlines the system’s requirements at run-time regarding availability, system performance characteristics, and resource consumption.
  • Deployment Plan Upfront – A deployment plan brings to the surface important issues rather than having to deal with them at a later stage. It ensures that the integration is deployed in a controlled and coordinated manner while minimizing the amount of downtime and disruption to business operations.

Use Pre-Built App Connectors

APIs are crucial for enterprise application integration as they help two or more applications seamlessly interact with each other especially when critical data is concerned. Web APIs are easily available on the internet and are made with XML or JSON to create connectors for apps. Since APIs provide a pre-packaged for connecting specific applications, connectors can help build and deploy solutions like ERP using plug & play models.

Maintain Data Quality

Maintenance of data consistency is another crucial best practice since integration can create issues with data quality. Since EAI systems exchange data between different applications, the chances of duplication, data loss & wrong entries are quite possible. Therefore, Proper mechanisms must be in place to prevent data quality issues as well as mechanisms that drive data transformation and validation.

Designing data structures is also important for flexible ways of adding new tables and fields. Common data rules like the canonical data model (CDM) can be applied across the organization to provide a single, consistent view of data across all integrated applications. Further, application connectors should be used during integration to reduce the time spent on writing manual integration connectors and improve reliability.

Invest in Integration Middleware

Utilize middleware platforms that offer tools and services for designing, deploying, monitoring, and managing integrations. When you invest in dependable middleware platforms, it enhances data security and scalability and lays the foundation for future integrations. Popular choices include MuleSoft, Apache Camel, and IBM Integration Bus.

Rigorous Testing and Continuous Monitoring

After implementing your EAI solution, it is essential to test it thoroughly to ensure that it meets your requirements. Regular monitoring is crucial, helping detect and swiftly resolve any emerging issues. This proactive approach ensures the seamless flow of data and processes, maintaining the efficiency and reliability of your integrated system.

Enterprise Application Integration (EAI) Examples

The deployment of EAI strategy varies across organizations and is influenced by the application integration tools, data patterns, and business-specific use cases. Some organizations prefer to build a point-to-point integration from scratch, while others prefer to use the application’s APIs if they have sufficient in-house resources. So, let’s explore some of the common approaches for enterprise application integration.

Examples of Enterprise Application Integration

Application-to-Application Integration

Application-to-application integration offers your business comprehensive visibility into business-critical operations and processes and end-to-end processing. These are often used to connect applications without the use of a middleware layer and is often used to connect legacy systems that do not have standard APIs. It is a good choice in cases where you have to integrate a small number of legacy systems. A2A integration also enables automation and enhances productivity by eliminating the requirement for manual data entry.

SaaS Application Integration

Currently, many companies use multiple SaaS applications throughout their entire enterprise. The SaaS application integration approach to EAI ensures seamless data flow and integration between these SaaS applications such as CRM, ERP, and HCP systems. This approach is affordable, secure, scalable and typically uses APIs to connect applications. For instance, a large enterprise may want to integrate its cloud-based CRM with its cloud-based e-commerce platform and existing legacy ERP system. It is particularly a good approach if your business is new to EAI, has limited IT resources, or looking to integrate cloud-based and on-premise applications to prevent black boxes and data silos.

On-Premise Application Integration

This approach is best when your business needs to integrate on-premise applications. Traditional approaches to internal application integration include specialized coding and can be expensive to implement and maintain. However, an enterprise service bus (ESB), a middleware platform that uses a rules engine to convert and route messages and enable communication across applications, is also a feasible option. The on-premise application integration approach is also preferred in cases where you need to meet specific compliance requirements that cloud-based EAI solutions cannot meet.

Enterprise Service Bus (ESB)

As a middleware platform that provides a central hub for routing and transforming data between applications, ESBs can be used to integrate all types of applications. While it is preferred in cases when you need to integrate a large number of applications and is highly customizable too, this approach is complex to implement and manage.


iPaaS solutions provide a suite of tools for developing and managing integrations. These offer a variety of pre-built connectors and integration templates that handle integration between SaaS solutions and cloud applications. These are easy to use, scalable, and usually hosted and managed by a third-party provider.

Now that you’re aware of the best approaches for enterprise application integration, let’s explore the various tools that help your business integrate different software applications and data sources.

Enterprise Application Integration Tools
