What is Cloud Computing ?


Cloud computing is the next level in the Internet's evolution, providing the means through which everything from computing power to computing infrastructure, applications, business processes to personal collaboration can be delivered to you as a service wherever and whenever you need.
The “cloud” in cloud computing can be defined as the set of hardware, networks, storage, services, and interfaces that combine to deliver aspects of computing as a service. Cloud services include the delivery of software, infrastructure, and storage over the Internet (either as separate components or a complete platform) based on user demand.
Cloud computing is offered in different forms: public clouds, private clouds, and hybrid clouds, which combine both public and private.
Cloud computing can completely change the way companies use technology to service customers, partners, and suppliers. Some businesses, such as Google and Amazon, already have most of their IT resources in the cloud. They have found that it can eliminate many of the complex constraints from the traditional computing environment, including space, time, power, and cost.

· On-demand self service:  Self service portal with service catalog that can automatically trigger workflows for routing, approvals and automated provisioning
· Broad network access: Service is accessible via internet or company network (private cloud) using various devices such as thick/ thin clients, laptops and mobile devices
· Resource pooling:  This implies timesharing of abstracted IT resources (compute, storage, network) from underlying hardware via various enabling technologies such as virtualization
· Rapid elasticity:  This requires one to dynamically increase or decrease IT resources provisioned, according to changing demands, where possible, automatically

· Measured service:  This means that capacity and utilization is being monitored and reported for capacity planning, demand and forecasting. It also includes monitoring and reporting service usage for the purpose of chargeback or showback.
