How does AS400 integration benefit your business?

What are the benefits of integrating AS400 with platforms and services?

In the rapidly evolving business environment of today, the seamless integration of diverse systems and technologies is indispensable for upholding competitiveness and operational efficiency. AS/400, often referred to as IBM i, has served as a dependable platform for businesses over many decades, furnishing a robust foundation for critical applications.

The integration of AS/400 with other systems and technologies presents an avenue to unlock novel potentials, optimize processes, and empower organizations to base their decisions on data-driven insights.

In this blog post, we will delve into the importance of AS/400 integration and how it can offer substantial advantages to your business.

AS/400, presently recognized as IBM i, represents a combined operating system and hardware framework with a track record of over three decades in active service. Renowned for its reliability, security, and scalability, it remains a favored selection for businesses operating mission-critical applications.

However, as businesses evolve, the need to connect AS/400 with other systems becomes imperative.

Why Integrate AS/400?

Streamlined Data Flow: Integration facilitates the smooth transfer of data between AS/400 and various systems, including web applications, mobile apps, and cloud services. This eradicates the necessity for manual data input, leading to decreased errors and time savings.

Enhanced Efficiency: Integration can automate business processes, making them more efficient. Tasks that once required human intervention can now be executed automatically, freeing up valuable resources for more strategic work.

Real-time Insights: Through the integration of AS/400 with analytics and reporting tools, you can acquire immediate insights into your business operations. This empowers data-centric decision-making, enabling swift responses to evolving market conditions.

Cost Reduction: Integration can lead to cost savings by reducing the need for duplicate data entry and manual processes. It can also extend the lifespan of your existing AS/400 infrastructure by making it more adaptable to modern technology.

Improved Customer Experience: Integration allows you to provide a seamless experience to your customers. Whether it’s online ordering, inventory tracking, or customer support, integrating AS/400 can enhance customer satisfaction.

Methods of AS/400 Integration

There are several methods for integrating AS/400 with other systems:

APIs (Application Programming Interfaces): Building APIs on your AS/400 system allows other applications to communicate with it. This method is ideal for real-time integration with web and mobile apps.

Middleware: Middleware solutions act as intermediaries between AS/400 and other systems, facilitating data exchange. Popular middleware options include IBM WebSphere and MuleSoft.

Data Integration Tools: Tools like IBM InfoSphere DataStage or Apache Nifi can be used to extract, transform, and load (ETL) data between AS/400 and other databases or systems.

Message Queues: Message queue systems like IBM MQ can enable asynchronous communication between AS/400 and other systems, ensuring data reliability and scalability.

Challenges and Considerations

While AS/400 iSeries integration offers numerous benefits, it’s essential to consider some challenges:

Security: Ensure that security measures are in place to protect sensitive data during integration. Implement proper authentication and encryption protocols.

Data Mapping: Accurate data mapping is crucial to prevent data inconsistencies between systems. A well-defined data mapping strategy is essential.

Legacy Systems: Legacy AS/400 applications might not be designed for easy integration. Legacy code may need to be updated or replaced to facilitate integration.

Scalability: Plan for future scalability as your business grows. Ensure that the integration solution can handle increased data volumes and system loads.


AS/400 integration is a powerful strategy for modernizing your business operations and staying competitive in today’s digital world. By connecting your AS/400 system with other technologies and applications, you can streamline processes, reduce costs, improve efficiency, and gain valuable insights.

However, successful integration requires careful planning, the right tools, and a commitment to security and data integrity. Embrace AS/400 integration as a catalyst for growth and innovation in your organization.
