e/Commodity computing

Information
has gloss	eng: Commodity computing is computing done in commodity computers as opposed to supermicrocomputers or boutique computers. Commodity computers are computer systems manufactured by multiple vendors, incorporating components based on open standards. Such systems are said to be based on commodity components since the standardization process promotes lower costs and less differentiation among vendor's products. A governing principle of commodity computing is that its better to have more lower performance, lower cost hardware working in parallel Scalar computing (eg AMD x86 CISC ) than it is to have less but more expensive hardware (eg IBM POWER7 RISC). At some point the number of discrete systems in a cluster or cloud will be greater than the MTBF for any hardware platform, no matter how reliable, fault tolerance must be built into the controlling software . Purchases should be optimized on cost per unit of performance, not just absolute performance per CPU at any cost.
