What is IBM i
IBM i is an integrated operating system for IBM Power Systems that combines the OS, a built-in DB2 for i relational database, and system management tooling in a single platform. It is used primarily by midmarket and enterprise organizations running long-lived business applications, commonly written in RPG, COBOL, or Java, and accessed through 5250/terminal, web, or APIs. IBM i emphasizes backward compatibility, integrated security, and centralized administration compared with general-purpose client and server operating systems.
Integrated database and OS stack
IBM i includes Db2 for i as a core component rather than a separately installed database. This reduces integration work for backup, recovery, security, and performance tuning because many capabilities are designed to work together. Organizations running transactional workloads can standardize on a single operational model for the OS and database layer.
Strong backward compatibility
IBM i is known for maintaining compatibility across releases, enabling long-lived applications to continue running with fewer rewrites. This supports gradual modernization approaches such as adding web services or new UIs while keeping core logic intact. For organizations with decades of business logic, this can lower migration risk compared with moving to a different OS family.
Centralized administration model
The platform provides integrated management concepts (objects, libraries, job control, and system services) and mature tooling for operations. Many routine tasks—user management, auditing, scheduling, and backup—can be handled within a consistent framework. This can reduce operational sprawl compared with environments that rely on multiple third-party components across the OS and database layers.
Hardware and ecosystem dependence
IBM i runs on IBM Power Systems and is not available as a general-purpose install on commodity x86 hardware. This limits deployment flexibility compared with operating systems that run across a wide range of devices and cloud instances. It can also constrain vendor choice for infrastructure and some third-party tooling.
Smaller modern developer pool
Many IBM i environments rely on RPG and COBOL skills, which can be harder to hire for than mainstream Linux/Windows skill sets. While modern options exist (e.g., Java, open-source packages, and APIs), organizations often need targeted training and modernization planning. This can increase staffing risk for teams without existing IBM i expertise.
Not a general client OS
IBM i is designed for server-side business workloads rather than end-user devices, mobile platforms, or broad consumer application ecosystems. It does not provide the same breadth of desktop/mobile application compatibility as mainstream client operating systems. Organizations typically pair it with other operating systems for user endpoints and certain modern application stacks.
