Of cloud computing’s three service models, software as a service (SaaS) is deployed most often. But that trend is shifting: A recent Yankee Group survey revealed that 24 percent of U.S. enterprises with cloud experience are already using infrastructure as a service (IaaS), an additional 37 percent plan to adopt it, and planned deployments are accelerating.
Cisco, too, is seeking to benefit from dynamic cloud service models, using models that offer reduced provisioning times and usage-based chargeback systems. We’ve gotten started by deploying the same unified computing and virtualization solutions we recommend to Cisco customers in our own private IaaS cloud. We call our internal cloud Cisco IT Elastic Infrastructure Services, or CITEIS.
