The Met Office, the United Kingdom’s national weather service, provides early, accurate severe weather reports. It strives to transform weather intelligence into a tool for business performance — and its goal is to empower organizations to use weather as an advantage. To process the massive amount of data it receives, the Met Office uses an IBM supercomputer that runs more than 100 trillion calculations in a second. These calculations are passed to post-processing and distribution systems that package them in a variety of forecasts and reports. Previously, those Linux-based, database-driven applications were supported by a distributed landscape of x86 servers. But as I/O and processing requirements increased, it grew increasingly complex and expensive. Today, the IBM z Systems mainframe is at the core of the Met Office’s IT infrastructure.
