What even is a mainframe? I’ve been involved in software and infrastructure for 20+ years, I understand data centres, servers, services, microservices, databases, HA/SPOF, clusters and all the cloud equivalents, but never came across a mainframe. It’s almost a legend – are mainframes a real thing? What do/did they do? What’s happening to them? Where are they?
In: Engineering
A mainframe computer is a high-performance enterprise server designed for mission-critical applications that demand exceptional levels of security, reliability, and scalability. They excel at processing massive datasets and performing complex calculations in real-time.
While the term “mainframe” might conjure images of bulky machines from the past, modern mainframes are quite compact and energy-efficient. They remain a crucial technology for many industries like finance, healthcare, and government due to their unparalleled combination of processing power, security, and reliability.
