Cloud as an enabler
The real benefit of cloud for these Enterprises will be that they can use it to fill the holes that come from operational or resource deficiencies. Have issues with maintaining IT assets? Great, outsource it to a cloud provider. Security problems? Instead of hiring tons of IT staff, why not look at augmenting your current teams with additional services. But most importantly, look at how your organization is using its resources, if there are more efficient ways to do things, then by all means, start the discussion. Cloud is meant to augment, not necessarily replace. The key to remember is that at the end of the day, if your are spending resources on services and processes that do not support your customers or your core business, maybe it's worth looking at how to leverage third party providers to get you back to the real purpose of your business, to drive value for your customers.
