Why mainframes for transaction processing?

Mainframes excel at transaction processing. IBM mainframes can perform far beyond distributed servers and can process huge volumes of transactions faster, more securely and more reliably. That’s why the largest companies with the highest number of transactions entrust transactional computing to z Systems® mainframes.

Transaction processing from IBM includes a family of enterprise application servers, as well as connectors and tools, which provide industrial-strength, online transaction management. Enterprise application servers on z Systems host applications written in a wealth of different languages, providing a secure, scalable and cost-efficient environment.
