AS400/iSeries Programming

In 1988, IBM introduced the AS400 system with several integrated systems featuring hardware (AS400) and an operating system (OS400). The system was used to perform data integration and several other core business functions.

With the passage of time, both the hardware and software of AS400 have undergone many upgrades, revisions, and name changes.   Today the AS400 system is popularly known as IBM iSeries, while the hardware is known as Power Systems and operating system is called as IBM i.

One of the powerful features of this system is its compatibility. All software applications created on the legacy AS400 -still run on the latest IBM I running on the POWER server with enhanced capabilities. This is the reason that companies that invested in an AS400 decades ago continue to leverage this system for their current needs.  This is the reason companies that opted for the stability of AS400 decades ago continue to leverage the systems capabilities and its newer technological features gain a competitive edge in the marketplace. Globally, there are over 100,000 companies that steadfastly rely on their AS400 architecture.

Some of the key advantages offered by iSeries Systems -are as discussed as below-

IBM iSeries is scalable:

IBM i is scalable, it supports business requirements that range from a very small to very large organizations. They can start with an affordable 4-core server and can go up to 256-core machines.

IBM iSeries is modern:

In addition, it supports a healthy mix of native and open source development languages. including RPG, Cobol, SQL, Java, .NET, PHP, C, and C++.

IBM iSeries is secure:

Everything including the software, databases, files, etc. – on the AS400 is object based. Due to this native architecture, it is impossible to hack data stored at the iSeries server. That’s the reason it is the preferred choice in several data sensitive organizations such as banking, finance and insurance companies.

IBM iSeries is reliable:

The system has successfully passed the test of time. It features enterprise-class reliability, which is the reason behind its immense popularity.

Then, Why are there so many questions the future of AS400 systems? When it Has Never Stopped Innovating and Delivered a World Class Software Development Platform at a Considerable Cost Advantage

One of the answers could be that AS400/iSeries systems are not often used for simple, popular office functions instead they are instead used to handle robust, business-critical applications like ERP, finance, or health information systems.

Apart from this, business leader fears that some of the technology veterans are reaching their retirement age.
