Unlock the Potential of AS400: Discover the Powerhouse of Enterprise Computing - Your Comprehensive Guide to AS400 Systems and Their Business Impact.

1. AS400: The Powerhouse of
Enterprise Computing
In the ever-evolving landscape of enterprise computing, certain systems have
managed to stand the test of time and continue to play a crucial role in
powering businesses worldwide. One such legendary system is the AS/400, now
known as IBM i, a versatile and robust platform that has been the backbone of
many organizations for decades. In this blog, we’ll explore the history, features,
and enduring legacy of the AS400.
A Brief History:
The AS400, short for Application System/400, was originally introduced by IBM
in 1988. It was a part of the IBM midrange family of computers and quickly
gained popularity due to its ease of use, reliability, and seamless integration of
hardware and software. Despite undergoing a few name changes over the
years, including iSeries and System i, the platform’s core principles remained

2. unchanged. In 2008, IBM rebranded it as IBM i to emphasize its integration with
other IBM offerings and modern technologies.
The Power of AS400:
1. Operating System Stability: One of the key factors that make the IBM i
platform exceptional is its rock-solid operating system. The IBM i OS is a
highly secure and stable environment that offers an object-based
architecture, integrated database, and a single-level storage model, which
hides much of the underlying complexity from users and developers. This
unique design simplifies maintenance and management, allowing IT
teams to focus on strategic tasks rather than mundane chores.
2. Scalability and Performance: From small businesses to large
enterprises, the IBM i platform is well-suited for a wide range of
organizations. It offers exceptional scalability, allowing businesses to grow
without compromising performance. The proprietary IBM Power Systems
on which IBM i runs provide high-performance computing capabilities,
making it an ideal choice for mission-critical applications and heavy
workloads.

3. 3. Legacy Application Support: Over the years, businesses have developed
numerous critical applications on the AS400 platform. IBM recognized the
importance of these legacy applications and ensured that they continue
to work seamlessly on modern IBM i systems. This level of backward
compatibility has saved businesses substantial costs and effort that would
have otherwise been required for complete system overhauls.
4. Integration Capabilities: IBM i is designed to work well with other IBM
products, such as WebSphere, DB2, and Power VM, as well as with various
open-source solutions. This integration capability enables businesses to
create comprehensive and dynamic ecosystems that can adapt to their
evolving needs.
5. Security and Reliability: Security is paramount for any business, and IBM
i delivers on this front. Its object-based security model allows
administrators to easily manage permissions and ensure data integrity.
Additionally, the system’s legendary reliability and self-healing capabilities
reduce downtime and improve overall system availability.
6. Modernization and Innovation: While the IBM i platform is renowned
for its stability, it hasn’t remained stagnant. IBM continues to invest in
modernizing the platform, incorporating the latest technologies, and

4. providing support for modern programming languages like Java, Python,
and Node.js. This enables businesses to build new applications while
leveraging the strength of their existing IBM i systems.
Conclusion:
In conclusion, the AS400, now IBM i, has earned its reputation as a powerhouse
in the world of enterprise computing. With a robust operating system,
exceptional scalability, unparalleled security, and a commitment to preserving
legacy applications, the platform continues to be the go-to choice for businesses
seeking reliability and performance.
