Many service providers today are implementing or investigating cloud computing to take advantage of its inherent operational advantages and as a platform from which to offer differentiated cloud-based services. By abstracting IT resources and services from the underlying infrastructure, service providers are achieving highly elastic, multitenant environments and savings. For example, cloud-based environments facilitate provisioning in minutes; time-to-market reductions of more than 50 percent; high server and storage utilization; 50 percent reductions in capital costs; and 25 to 30 percent reductions in operational costs. 1
At the same time, cloud-based services are highly attractive to providers’ enterprise customers. Service provider-based cloud services offer greater scalability and performance without requiring premises-based infrastructure and management. Self-service, scale-on-demand, and pay-per-use features increase user convenience and IT flexibility, while automated recovery and cloud-based backup significantly enhance risk management.
The good news is that service providers today are uniquely positioned to take advantage of cloud computing. Infrastructure as a service (IaaS) -- a cloud utility architecture -- provides an easy entry point for many service providers who are already expert at provisioning, managing, and scaling infrastructure-based services for multiple customers. IaaS helps enable service providers to increase return on investment through existing infrastructure and to deliver high-margin multitenancy services and support new competitive offerings. According to the Cisco Internet Business Systems Group, a 2009 study has forecast IaaS service revenues to be approximately $15.6 billion by 2013.
