The IBM® mainframe remains a widely used enterprise computing workhorse, hosting essential IT for the majority of the world’s top banks, airlines, insurers and more. As the mainframe continues to evolve, the newest IBM Z® servers offer solutions for AI and analytics, blockchain, cloud, DevOps, security and resiliency, with the aim of making the client experience similar to that of using cloud services.
