There is a popular opinion that the AS400 system is outdated and not in the same demand as it used to be. But is it so? What benefits does the AS400 offer that today’s businesses can’t afford to miss? What about an IBM i modernization? Let’s figure it out.

What Is AS400?

AS400 (Application System/400) is a highly secure, stable, reliable, and scalable mid-range computer system that provides a wide range of functions. IBM released it in 1988, but it is still very popular today.

The AS400 is constantly being developed and updated to provide all the functionality that today’s business needs. This IBM system provides high compatibility. This means that programs that work using outdated technologies can run on it without modification.

IBM renamed the AS400 systems several times. It was called iSeries, System i. The latest version, which is current now, is called IBM Power Systems.

What Is The AS400 Operating System (iSeries)?

The AS400 operating system was released simultaneously with the AS400 hardware and also gained a lot of popularity. It has several advantages:

  • Built-in database.
  • Backward compatible with earlier versions of the IBM AS/400. This allows you to switch to a new version of the platform without reinstalling applications.
  • The IBM AS400 is a turnkey operating system and can run for long periods with little or no IT support.
  • Automatic scheduling of system maintenance and identification of problems in the system.
  • The programming data needed to run the IBM AS400 is already integrated into the base OS. This eliminates the need to purchase and install software separately.
  • The ability to quickly switch from one task to another.
  • The AS400 operating system is integrated with server technologies such as the DB2 Universal Database and Lotus Domino software.

What Is The Difference Between IBM i And AS400?

Comparing AS400 and IBM i is not correct, since AS400 is hardware, and IBM i is software.

AS400 is a server that has its own OS/400 operating system. IBM released it in 1988. After that, it was constantly updated and in 2008 it received the name Power Systems.

OS/400 is an operating system that was also actively developed and had different names. Now it is called the IBM i and it works on IBM Power Systems.

Is The IBM AS/400 Software Dead?

Today, many experts consider the AS/400 system to be dead. However, we cannot agree with this. Even though the AS400 system has been operating for the past few decades, it is constantly evolving, using modern technologies and satisfying all modern business needs.
