Virtual servers in the cloud model. Basically they are providing Infrastructure as a Service. If you need to run your application, you can go to their site, configure your own server with your required configuration and software libraries and they will generate a server on the fly for you! Basically all this magic has come about thanks to virtualization technologies which allow you to create software servers independent of the hardware infrastructure running them. These VMs can be scaled and migrated depending on the need.

Amazon’s Elastic Compute Cloud (EC2) allows the imaging of servers and the use of web services to provision these images on specified virtual platforms. It currently allows a range of basic, to intermediate, to high-performance spec’ed platforms and these are priced on an hourly basis.
Using the Amazon Simple Storage Service (S3) a complete application environment can be provisioned from the stored images in a short period of time, used for a defined purpose and period, and then decommissioned.
The main challenges that remain for Cloud Computing

Quick definition: Cloud Computing is an Internet based platform geographically distributed and developed to provide real-time scalable resources and provided “as a service” over the Internet to users who don’t need to have deep knowledge or expertise on technology infrastructure. The concept incorporates software as a service (SaaS), and other well-known technology trends.
Cloud computing services span a wide scope, from virtualized low-level computing and storage to full business services. Understanding the spectrum of cloud services and the characteristics of each service category is essential in determining when, where, how and why to apply cloud computing.
