“You think about technology waves, and every once in a while you get one that you know is meaningful, that actually changes the way companies spend their money and invest in solutions; it actually changes the way the tech industry itself is shaped — and cloud computing is one of those things.” Ted Schadler, vice president and principal analyst, Forrester Research.Finding the sunshine in the cloud
We can see clearly now,the haze has goneCloud is here to stay; more and more organisations areusing cloud services — no great surprise when everybusiness is looking to make efficiency and cost savingsin these difficult times.Cloud computing is a top-of-mind consideration formost CIOs, finding that most organisations are lookingto the cloud for ‘extension’ — the capability to taketheir business in new directions faster — rather thansimply as a method of cost management.The benefits of moving to cloud architecture arewidely accepted and potentially huge:• Increased agility due to rapid provisioning and de-provisioning of resources;• Significantly-reduced capital expenditure and fixed costs;• A faster return on investment thanks to pay-as-you-use commercial models;• Easy availability of services to a mobile workforce;• Less time spent managing technology and software and more time spent managing information and And now the hype haze has cleared we have data to drive business innovations. a much clearer picture of how to get the best from the cloud — and what could be holding back take-up.

All that’s happening now is that the relatively new model of the cloud is highlighting the trust-control and security policy issue afresh. What CIOs and IT managers need to cultivate is mindful trust — being aware that exploiting the cloud requires trust and a careful assessment of where to place it. Mindful delegation of responsibility frees the IT professional to take on a more strategic role within the organisation.
