IT System Integrations: Types, Examples & Solutions

Information technology (IT) systems integration has become an increasingly important factor for businesses looking for ways to adapt to the volatile economy by improving efficiency or reducing costs without compromising quality while increasing customer satisfaction.

With the increasingly competitive global marketplace, the ability to quickly and inexpensively integrate disparate IT systems into one cohesive and efficient system can be a crucial competitive advantage. In this blog post, we'll take a look at how IT system integrations work, different types of system integrations, and some of the challenges along with solutions available to businesses.

What is IT System Integration?

IT system integration is the process of bringing together various component subsystems into one complete system. The goal of integration is to achieve operational synergy and efficiency by sharing data and resources across the component systems. In order to achieve this, businesses need to carefully plan and execute an integration strategy.

Most system integrations fall into one of the following categories: Horizontal and vertical.

  1. Horizontal integrations occur when component systems are brought together at the same level, such as when two companies merge their IT systems.
  2. Vertical integrations occur when component systems are brought together at different levels, such as when a company integrates its ERP system with its CRM system.

Types of Integration Systems

Application Programming Interfaces (APIs)

Application Programming Interfaces, or APIs, are a type of software that enables two or more different applications to communicate with each other in order to share data and functionality. APIs provide a standardized way for applications to interact, allowing developers to easily access information and services from other applications.

This helps to speed up development time, as developers don't need to build complex functionality from scratch. APIs are used in a wide range of applications, from websites and mobile apps to enterprise software development and cloud computing. By using APIs, developers can build powerful applications quickly and easily, making them an invaluable tool for the modern software developer.

Enterprise Service Bus (ESB)

An Enterprise Service Bus (ESB) is a software architecture that enables applications to communicate with one another. It acts as a bridge between applications, providing an easy and secure way for them to exchange data and messages. ESBs can be used to integrate existing applications and create new ones, allowing organizations to create complex systems from simple components.

In addition to making communication between applications easier, ESBs can also provide other benefits. They can improve performance by reducing the amount of data that needs to be exchanged, as well as providing access control and security measures. They can also help reduce the cost of creating and maintaining complex systems, as well as improving scalability.

For organizations looking to integrate their existing applications and create new ones, an ESB can be a powerful tool. It can enable them to quickly and easily create complex systems from simple components, saving time and money in the process.

Point-to-Point (P2P) Integrations

Point-to-Point (P2P) integrations are a powerful tool for organizations that need to connect disparate systems. By leveraging the power of P2P, organizations can quickly and easily create direct integrations between two systems without the need for an intermediary such as an API gateway. This type of integration is often used to connect legacy systems or to synchronize data between two different applications. P2P integrations can also be used to enable real-time communication between two systems, allowing for faster and more efficient data sharing. In addition, P2P integrations can be used to automate processes such as order fulfillment and payment processing, eliminating the need for manual intervention.
