IBM iSeries
Updated on Apr 15, 2025
IBM i is a fully integrated operating system, meaning the database, middleware, security, runtime and hypervisor are integrated into the stack and licensed as one solution. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008.
