The joint avaialiability of high-speed Internet connections and high-performance data centre forms the basis for the cloud computing infrastructure. Cloud computing goes beyond traditional Software as a Service(SaaS) and harness the potential of open source,open systems and open standards and a range of scalable technology enabled services. Cloud computing has the following payoffs.
- Scaling benefits without scaling costs : with the basic motto " rent a resource rather than buying or building a new one" cloud computing promises to provide services without escalting costs and associated management overheads.
- Use numerous networked computers to create supercomputing capabilities
- Pay for space and storage on as-needed basis
- Eliminates the need for desktops and complex local networks
- Provide access to scalable resources without assocaited ownership costs
Next. the cloud computing in combination with SOA (software oriented architectre) interface allows the exposure to loosely coupled services, making seamless access and integration possible and help create a new range of applications.
