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.
CITEIS is Cisco IT’s first venture into cloud computing. But we eventually plan to have all three types of cloud services: IaaS and SaaS, as well as platform as a service (PaaS), which involves dynamic access to development tools and associated storage. The idea is that when we have all three cloud types in place, we’ll basically be delivering IT as a service throughout Cisco, so all IT services can be self-provisioned and charged back based on consumption.
For now, the focus is on CITEIS. Following the retrofit of several Cisco data centers to include components of CITEIS, its first complete deployment will be in our new facility under construction, Texas Data Center 2 (DC2). This CITEIS deployment is an important milestone in Cisco IT’s roadmap, and we’ve been capturing our progress in our Texas DC2 online chronicle, Cisco Data Center 2011-Texas. To learn about our plan to implement IaaS with a full chargeback system and use of standardized, self-service IaaS bundles to reduce provisioning times from months to minutes, watch the video IaaS to Deliver IT Self-Service.
