As400

The AS/400's longevity is largely due to its unique, forward-thinking architecture:

: This layer separates applications from the underlying hardware, allowing companies to upgrade to new processors (like Power10) without modifying their software. The AS/400's longevity is largely due to its

: Hardware consolidated into IBM Power Systems , with the operating system becoming IBM i . Core Architectural Features and devices—is treated as an object

: Everything on the system—files, programs, and devices—is treated as an object , which significantly enhances security and stability. The AS/400's longevity is largely due to its

Over worldwide—including 16,000 banks—still rely on this platform for mission-critical workloads.
