5. A style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service to external customers using Internet technologies. What is ‘the cloud’? An emerging IT delivery model —cloud computing—can significantly reduce IT costs & complexities while improving workload optimization and service delivery. Cloud computing is massively scalable, provides a superior user experience, and is characterized by new, internet-driven economics. Prefer to call it x as a Service, where x is a consumable service resource that customers can buy in an on-demand fashion over the network. Cloud Services enable customers to procure infrastructure services where and when they need them and pay for them on a consumption based model Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction The Consumerization of Information Technology through internet-like consumption & delivery models X as a Service server storage networking improved economics through sharing
