IBM i / AS400

IBM i, previously known as AS400, is a midrange server designed for small businesses and departments within large enterprises. Rebranded to IBM System i, it also includes the software required to run and manage the server, making it incredibly versatile. The operating system for IBM i is integrated with its hardware and allows for resource sharing among all its users, making it a popular choice for businesses looking for cost-effective solutions. With the advent of IT advancements such as cloud computing and migration, administrators of IBM i / AS400 have a wide range of tools, including iSeries IBM, at their disposal. Moving on to the contrasting aspects of IBM i vs. AS400, it is to note that both essentially represent the same technology. 

However, the name change represents IBM’s broader strategy to unify divergent product lines under a more cohesive brand. Historically, the term AS400, or Application System/400, was used to refer to these servers and their operating systems. Later, as part of IBM’s rebranding efforts, AS400 was renamed to System i. The current term for the platform, IBM i, represents the integrated nature of the system, with built-in database, security, and web services functionalities. 

The AS400 operating system is renowned for its:

  • Robustness
  • Stability
  • Backward compatibility

It can run applications written for System/36 and System/38, two of IBM’s predecessor systems. Also, newer applications developed in modern languages like Java and PHP can seamlessly run using the AS400 operating system. This backward compatibility, paired with future-proof capabilities, makes the AS400 operating system a reliable choice for enterprises. 

However, learning to use AS400 can come with a steep learning curve. Beginners are recommended to engage in AS400 software training, where they are taught the basics of the system, the language it uses, and the commands needed to navigate through it. Decoding the system’s green screen interface and jargon-based language is an integral part of the training. On completion of the training, newcomers are equipped to easily configure, secure, and manage this system. 

AS400 systems are often used to host several business-critical applications, prominently including accounting software. This type of software is known for its:

  • High-speed data processing capacity, which can rapidly perform financial computations and reporting. 
  • Robust security measures, backed by IBM’s reputation, give enterprises the confidence to process and store sensitive financial information on these platforms. 

The other topic worth mentioning is the IBM AIX documentation. AIX is IBM’s version of the Unix operating system. Comparing AIX vs. AS400, the primary difference lies in their hardware compatibility; whereas AIX is designed to run on IBM’s RS/6000 systems, AS400 runs on IBM’s Power Systems. IBM AIX documentation provides extensive information about installing, customizing, and managing AIX systems. Finally, given businesses’ increasing reliance on the cloud, AS400 to cloud migration is a hot topic. 

The process involves moving applications, data, and other business elements from the AS400 platform to cloud-based storage systems, improving accessibility, scalability, and cost-effectiveness. However, AS400 migration should be executed strategically, considering the complexities of migrating business-critical applications.


With its robust and powerful features, IBM AIX takes a fortified position on the battleground of operating systems.
