"The Enduring Power of the IBM Mainframe: A Closer Look at its Operations and Resilience"
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.
