Cloud Computing: The future of mainframe computing – Legacy or legendary?
July 28, 2013
Grazed from ITProPortal. Author: Derek Britton.
The demise of mainframe computers has been predicted for decades, but they still thrives as the reliable core processing workhorse for many industries. In fact, IBM was able to report over 50 per cent increase in mainframe revenues in 2013. But as the technology world evolves, games are changing, and the relevance and apparent suitability of the mainframe world is struggling to keep pace with the expanding demands of today’s information-hungry customers, including trends such as cloud computing.
This is compounded by recent high-profile mainframe outages that have dented not only customer service but also the reputation (and share price) of some major organisations. Can mainframe overcome the core challenges it faces? These include its assumed high cost, the IT skills crisis, and a perceived irrelevance to modern computing…
In many large-scale organisations, the mainframe is considered powerful, secure, cost effective and unrivalled in reliability. However, when an application’s processing consumption is rising, or its response times are not meeting users’ real-time expectations, often the cost benefit justification of these systems are jeopardised. This is either because MIPS/MSU costs continue to rise and in turn force hardware upgrades, or simply because the systems are becoming too complex and expensive to maintain…
