So, are you ready to explore the operating system that you might not know but definitely should? Let’s get started.
The Genesis: AS/400
When IBM unveiled the AS/400 (Application System/400) in 1988, it wasn’t just introducing another computing system—it was revolutionizing the way businesses thought about integrated environments. The AS/400 was engineered to offer an all-in-one solution, combining hardware and an operating system optimized for business applications. One of its groundbreaking features was the “TIMI” (Technology Independent Machine Interface), which enabled the hardware to evolve without requiring changes to software applications1.
The market reception was beyond expectations; over 2000 businesses reportedly switched to AS/400 within the first month of its release. The AS/400 was initially embraced for its role in manufacturing and inventory management systems, but it quickly gained traction in other sectors like finance and healthcare due to its reliability and scalability.
Another hallmark was the integration of the DB2 database within its architecture. This was a game-changer for companies looking for database solutions that were efficient and reliable3.
The AS/400 was also noted for its RPG (Report Program Generator) programming language. At that time, RPG was extensively used for business applications, and its compatibility with AS/400 made the transition easier for many organizations.
It was not just a computing system; it was a computing ecosystem designed with businesses in mind. The AS/400’s focus on offering an integrated, reliable, and efficient system laid the groundwork for what IBM i would eventually become.
The AS/400 to iSeries Transition 🔄
When the calendar flipped to the 21st century, so did IBM’s approach to its beloved AS/400. Say hello to its next evolutionary phase: the iSeries! The iSeries wasn’t just a rebranding; it represented a fundamental shift aimed at capturing the essence of emerging technologies and business needs.
Rebranding and Technological Improvements 🛠️
The name change from AS/400 to iSeries was reflective of a broader vision. iSeries integrated numerous technological improvements, including advanced support for Java and WebSphere, IBM’s web application server. But why stop there? The iSeries also began to offer compatibility with Linux, opening up new avenues for software development and system integration🌐.
Introduction of New Programming Languages 👩💻
While RPG and COBOL continued to hold their ground, iSeries extended its arms to embrace other programming languages like Java and C++. This diversification allowed for a richer ecosystem that could cater to a broader range of business applications. For example, companies that were traditionally entrenched in Java-based applications could now seamlessly transition to the iSeries environment without rewriting their existing code✨.
Extensions for Web-Based Applications 🌍
Web technology was transforming the world, and iSeries wasn’t going to be left behind. IBM incorporated extensions that made it easier to deploy web-based applications. With features such as integrated web services, businesses could now connect iSeries to external databases and web applications efficiently. One notable case study here is that of a major online retailer that leveraged iSeries to integrate its eCommerce platform, effectively harmonizing its online and offline inventories🛒.
The iSeries to System i and IBM i Evolution 🌱
IBM isn’t known to rest on its laurels, and this was no different with the iSeries. The platform evolved into what was known as System i, and eventually, took on its present avatar: IBM i.
Overview of the System i Platform 🏗️
System i was a significant leap forward. It retained all the qualities businesses loved about iSeries, while introducing enhanced networking capabilities and hardware options. The idea was to build a platform that was more modular, offering an à la carte menu of options for businesses of all sizes 🌐.
Integration of UNIX, Linux, and AIX 🤝
System i upped the ante by offering support for UNIX, Linux, and IBM’s proprietary AIX operating systems. This open architecture made System i incredibly versatile, allowing for a more extensive range of applications and services to be hosted on the same hardware. One could argue that this was System i embracing globalization, welcoming multiple “languages” into its fold 🌍.
Transition to IBM i and its Modern Capabilities ⏩
The System i then paved the way for IBM i, which extended capabilities even further by enhancing cloud compatibility, web services, and API support. IBM i today is not just a system; it’s an ecosystem that offers an incredible range of applications from data analytics to mobile compatibility 🚀.
