"The Enduring Power of the IBM Mainframe: A Closer Look at its Operations and Resilience"
Originally Published 2 years ago — by Ars Technica
Mainframe computers, such as those manufactured by IBM, are still relevant today, with an estimated 10,000 in use by large companies worldwide. These purpose-built machines are designed to handle massive data workloads and provide high throughput and redundancy for critical operations like high-volume financial transactions. With up to 240 server-grade CPUs, large amounts of RAM, and petabytes of storage, mainframes ensure 99.999% uptime and rapid response times. While cloud and cluster platforms are competitors, they often lack the cost-effectiveness and reliability of mainframes.
