The value of the mainframe - The modernised mainframe still has a bright future as Enterprise Server 3.0

For the largest systems, it is simply easier (and probably cheaper) to provide the levels of throughput, resiliance and security that a large regulated business requires on a mainframe, but the mainframe can become a risk-averse silo, acting as a brake on the evolution of a mutable business. The mainframe must be modernised as “just another – very powerful – server”, playing an equal part in enterprise IT, and its cultural silo must be dismantled.
