Mainframes are complex but reliable and fast processing platforms. Their usage outlays constitute a significant proportion of an organisation's IT budget as costs incurred can sometimes be high. Furthermore, according to experts, organisations should expect a 15 to 20% annual increase in CPU resource consumption. Reducing the costs of a company's mainframe environment while minimising risk is therefore a key challenge facing every organisation's IT department. For this Spanish retail bank, GFT improved IT resource consumption and performance by a total of 7966 minutes per month.
