IaaS will drive further consolidation among data center outsourcers and hosting providers. Why? Because the flexibility and cost advantage of IaaS cloud providers requires data center outsourcers and hosting providers to either adopt IaaS or move into niches.
With standards driving down IaaS licenses and implementation costs, data center outsourcers and hosting providers could move into IaaS either on their own (which requires sufficient scale) or through partnerships. It’s easy to imagine a net of partnering providers offering IaaS under a virtual umbrella as a standardized offering to customers.
