“AS400” and “green screen” have become synonyms now, and you will get various articles and blogs out there describing the platform – but none of them paint a simple and easy to remember picture for the audience. All the information about AS400 is very disorganized and hence difficult to consume or comprehend for a non-technical business reader.

In this blog, we have deeply analysed the IBM AS400, i.e., apart from its “green screen” identity and brought together a lot of different pieces of information on AS400 – so that when you finish reading this blog – you leave better informed. Also, the blog is written by keeping CIOs, CEOs, CTOs, IT developers, and vendors in mind, who think of it still being a green screen software. This single thought has wasted millions of dollars on failed projects, and to some of the people, have costed their job.

What Actually AS400 is?

IBM AS400 or IBM iSeries or IBMi is an application server used by large organizations because of its proven scalability, security, robustness, and low cost of ownership (TCO – Total cost of ownership) compared to IBM mainframe (IBM z)

Every company that used AS400 wants to reap the benefits of its large volume data storage capacity and valuable information stored in it.

Also, the introduction of new technologies forces companies to modernize AS400 systems and harness more excellent value. However, due to some limitations, companies face more significant challenges to update the AS400 systems.

But in the case of AS/400 systems, IBM does not charge customers based on transactions, i.e. (MIPS – Million Instructions per Second), instead it is a sunk cost. In simple words, it’s not that difficult or expensive to modernize the AS400 systems, and the updated version will deliver benefits like – reduced Total Cost of Ownership (TCO), transparency in hidden data, and increased system responsiveness while delivering enduring business value.

The footprints of AS400 are extensive in the IT landscape. Several technologies and supporting software are involved in the process; a one-stop solution provider for AS400 modernization is likely to succeed.
