AS400 iSeries:

The IBM AS/400, also known as the IBM iSeries, is a series of midrange computer systems that have been in use since the late 1980s. The IBM i operating system (formerly known as OS/400) is the exclusive operating system for these machines.

The IBM i operating system was designed to be user-friendly and intuitive, while also providing a secure and reliable platform for business applications. It supports a wide range of programming languages, including RPG, Java, C++, and Python, among others.

One of the main advantages of the IBM iSeries is its scalability. It is designed to support businesses of all sizes, from small startups to large enterprises. This means that as your business grows, you can easily upgrade your system to meet your changing needs.

Another key feature of the IBM iSeries is its security. The IBM i operating system has a number of built-in security features, such as object-level security, authentication, and encryption. These features help to ensure that your data and applications are protected from unauthorized access and cyber-attacks.

In addition to its security features, the IBM iSeries also offers high availability and disaster recovery capabilities. These features allow you to minimize downtime and quickly recover from system failures or other types of disasters.

The IBM iSeries also provides a number of tools and utilities that make it easy to manage and maintain your system. These include system management tools, performance monitoring tools, and backup and recovery tools, among others.

In recent years, IBM has continued to update and modernize the IBM iSeries, adding new features and capabilities to keep pace with changing business needs. For example, the latest version of the IBM i operating system, IBM i 7.4, includes new features such as support for containerization and open-source software.
