IBM mainframes revolutionized enterprise computing since the 1960s, processing critical transactions worldwide.

About this subject

IBM mainframes, such as the System/360 introduced in 1964, marked the beginning of modern corporate computing. They were the first computers to allow different models to run the same software, setting a compatibility standard that drove the industry forward. These systems were designed to process massive volumes of data simultaneously, with exceptional reliability and security. Companies in sectors like banking, aviation, and government rely on them for essential operations such as financial transactions and flight reservations. Over the decades, IBM continued to innovate with the 370, 390, and currently the IBM Z series. Modern mainframes use advanced processors, integrated encryption, and virtualization capabilities to run thousands of workloads in hybrid cloud environments. Despite the rise of distributed servers, mainframes remain relevant due to their competitive total cost of ownership and processing power of up to 12 billion instructions per second. A curious fact is that barcodes, widely used in retail, were initially processed by IBM mainframes. The company also developed the OS/360 operating system, one of the first to manage multiple tasks simultaneously. Today, IBM mainframes handle 87% of all credit card transactions and 90% of global airline reservations, demonstrating their ongoing importance in the global IT infrastructure.
