The mainframe was born some 50 plus years ago when the government needed a machine to support advanced research. Since that time it has taken its rightful place in the world's financial transactions, transportation management, health care and industry management. Most of that code was written in COBOL and VSAM and ran on systems from CICS and IMS to DB2. Today it still fulfills those venerated roles but it has evolved into the most powerful, flexible, reliable server in the industry, running new workloads from Java to Linux. This is the machine that supports tens of thousands of users working with hundreds of terabytes of data, with response times still in sub-seconds. This is not your father's mainframe.
