IBM AS400 is the Most secure, Stable, Reliable, and Scalable Platform for Web & Mobile Business Applications. It is an application system from IBM. AS/400(Application System/400) emerged in 1988. It included a group of user-friendly computers for SMEs.The initial AS/400 B-series models included the IBM 9404 and IBM 9406. The AS400 operating system quickly became a success. History shows that IBM had shipped almost half a million as400 models by 1997. There was no doubt that the Application System 400 was helpful before the immense growth of technology. Even though some organizations still use it, most companies have stopped or have integrated it with modern software. This leads to this question: is the IBM series still alive, or is it dead? We will try to answer this question below.

History of IBM 400

The first IBM AS400 computer system emerged in 1988. It consisted of the operating system called the OS/400 and the hardware system called the AS/400. Additionally, the first production had an integrated database and other core functions. Over the years, the AS/400 and OS/400 have seen many upgrades. 

Before it came to be, IBM had made a computer using the object-based OS in 1978. It was called System/38. The relational database found is similar to the Db2 we know now. Also, some of its concepts made the AS400 software system run smoothly. In 1983, the company made another computer system called System/36. It used RPGII as the primary programming language, and it was only a file management machine.

In 2000, IBM branded the AS/400 again to eServer iSeries and had the OS/400 operating system. This became a server for running internet businesses. In 2006, the company released the iSystem server which consisted of the i5/OS operating system. It became an alternative for companies that would not run the Windows OS. 

In 2008, the company released the Power Systems or IBM Power. It was a combination of i5/OS (now called IBM i) and the Unix (also called AIX) OS. Power Systems has a built-in database called DBMS, DB2/400. It provides web-based applications that are easy to execute in MySQL or PHP with an Apache server. Although IBM has rebranded its product over the years, it has retained compatibility. 

Hence, it is easy to run the initial AS/400 programs in modern Power Systems without an issue. As a result, some companies have been unable to stop using the AS400 i series. There is hope because IBM updates its IBM i series every three years. 

What are the characteristics of the AS/400 e-server i-series?

The main characteristics of the AS/400 include the following: 

• Object-based OS – The object-based OS has unique things not available in other kinds of operating systems. For instance, it has single-level storage. As400 System i is more secure and stable for running businesses because of its uniqueness. 
• Broader integration components – The AS400 software is easy to use with other software systems. It has several features for easier integration. These include web application servers, web services servers, the DB2 relation database, and more. All combined, these components can do more than 300 tasks. 
• Efficient apportioning – The as400 mainframe iSeries is a firmware-based virtualization system that works better than some modern server applications.
• The administrator interface works well – IBM provides great technologies for doing routine tasks within an organization. It is not the case with Linux and Windows as they have to source tools from other vendors. 
• It is cheaper to run – The IBM i-series as400 entails fewer hardware servers. So it is cheaper and easier to place in your data center. 

Who still uses AS/400?

Up to today, some companies continue to use AS/400. About 10.1 percent of organizations run IBM i with their servers, according to iDatalabs. After HP, IBM AS400 comes second in terms of popularity. IBM’s product use is more prevalent in the manufacturing and IT fields. However, the use of the AS 400 operating system runs across many industries around the globe.
