Big Iron is a term originating from the mainframe computers era, which was massively used by large businesses for critical applications, including industry processing, consumer statistics, and enterprise resource planning. The term predominantly symbolizes the power and durability of these bulky, and resilient machines. Mainframe computers also known as “Big Iron” due to their large sizes, were widely utilized because of their robustness, reliability, compatibility, high-performance maintenance, and security of data, thus giving them a predominant role in bulk data processing.Primarily, Big Iron is used for applications requiring high volumes of data processing such as census, consumer statistics, and financial transaction processing. For instance, banks and governments typically use Big Iron for processing transactions and maintaining records because mainframe computers can process billions of simple transactions per day. Furthermore, due to its superior fault tolerance and reliability, mainframe computers are also used for applications that demand high uptime. Despite the advent of new technologies, Big Iron’s purpose remains relevant in modern times, especially in sectors where large-scale, reliable data processing is essential.


1. IBM’s Mainframes: One of the earliest and most iconic examples of “Big Iron” would be the mainframe computers developed by IBM, such as the IBM z13 system. These systems are renowned for their high performance, scalability, and reliability, and are frequently used by large businesses and organizations for transaction processing and other mission-critical tasks.2. Government Supercomputers: Another example could be the supercomputers used by government located in high-security data centers. These “big iron” machines are used for everything from climate modeling to nuclear weapon simulations. An example is the Oak Ridge National Laboratory’s “Summit” supercomputer.3. Large-Scale Transaction Processing Systems: Many banks and financial institutions use “big iron” systems for their transaction processing needs. These systems need to be able to process millions of transactions daily, and as such, they are often large, powerful mainframe computers. Bank of America, for example, uses such systems to handle their vast amounts of transaction data.
