Real World Examples of Cloud

Some Real world examples
NASA’s Nebula:
NASA describes Nebula as a combination of infrastructure, platform, and software as a service, and the space agency has created IT architecture in support of that. Components include the Eucalyptus software developed at the University of California at Santa Barbara, the Lustre file system deployed on 64-bit storage nodes, the Django Web application framework, the SOLR indexing and search engine, and an integrated development environment. Nebula will be compatible with Amazon Web Services, which means AWS-compatible tools will work with it and Nebula virtual servers can run on Amazon's Elastic Compute Cloud.

Nebula is a Cloud Computing pilot under development at NASA Ames Research Center. It integrates a set of open-source components into a seamless, self-service platform, providing high-capacity computing, storage and network connectivity using a virtualized, scalable approach to achieve cost and energy efficiencies. Nebula is currently being used for education and public outreach, for collaboration and public input, and also for mission support.
Amazon Web Services:
Amazon Web Services (AWS) [11] is the most successful IaaS provider to date. Amazon has huge server farms that support the Amazon website and plenty of experience with running a reliable multiple server operation. It was decided to take the skills, technologies and hardware they had developed or acquired and offer them for hire to other organizations.

Amazon's Elastic Compute Cloud (EC2) offers, as the name suggests, server power that can grow and contract in line with an organization’s demands. Users of the service pay (at the time of going to press) ten cents (USD) per hour for the most basic server and the menu goes up from there. This offers a lot to start-ups or small businesses who can then afford to access server and storage capacities that would otherwise drain vital capital.
