In this article, we’ll explore the journey of the IBM iSeries AS400, from its origins to its present-day applications, and how consulting services play a crucial role in helping businesses leverage its full potential.

The Origins of IBM iSeries AS400

A Revolutionary Midrange System

The IBM iSeries AS400 was launched by IBM in 1988 as a midrange server designed for small and medium-sized businesses. It was built to handle a wide range of business applications, including accounting, inventory management, and enterprise resource planning (ERP). The system’s standout feature was its integration of hardware, software, and storage, which allowed it to run efficiently and with minimal downtime.

At the time of its release, the AS400 revolutionized the IT world by introducing a platform that required less maintenance and technical expertise compared to mainframe computers. Its ease of use and reliability made it a popular choice for businesses that needed a powerful, all-in-one solution.

Key Features That Set AS400 Apart

Several features made the AS400 a game-changer in the late 1980s and early 1990s:

1. Integrated Operating System
   The AS400 introduced the OS/400 operating system, which was tightly integrated with the hardware. This eliminated the need for complex configurations and ensured seamless performance.


2. Backward Compatibility
   IBM designed the AS400 to be backward compatible, allowing businesses to run older applications without disruption.


3. Security
   The platform was built with robust security features, including object-based architecture, which helped protect data and applications from unauthorized access.


4. Scalability
   The AS400 was designed to grow with businesses, offering scalability that allowed organizations to expand their operations without significant hardware upgrades.

The Transition to IBM iSeries

Rebranding and Modernization

In the early 2000s, IBM rebranded the AS400 as the iSeries, reflecting its evolution into a more versatile and modern platform. With this rebranding came several updates, including support for modern programming languages like Java, greater integration capabilities, and improved performance.

One of the most significant changes during this phase was the introduction of the IBM Power Systems architecture, which brought even greater computing power and efficiency to the platform.
