CLOUD COMPUTING
The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.
The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams.
Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet
Its a new technology.
Cloud computing is a general term for anything that involves delivering hosted services over the Internet
Cloud computing is defined and characterized by massive scalability, superior user experience, and new, Internet-driven economics
These services are broadly divided into three categories:
Infrastructure-as-a-Service (IaaS),
Platform-as-a-Service (PaaS)
Software-as-a-Service (Saas)
Infrastructure-as-a-Service like Amazon Web Services provides virtual server instances with unique IP addresses and blocks of storage on demand.
Platform-as-a-service in the cloud is defined as a set of software and product development tools hosted on the provider's infrastructure.
In the software-as-a-service cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal.
Cloud computing represents a true paradigm shift in the way IT and IT-enabled services are delivered and consumed by businesses
Cloud computing focuses on the user, and offers highly efficient acquisition and delivery of IT and information services
Cloud computing - has evolved to address the explosive growth of Internet-connected devices, and to complement the increasing presence of technology in our lives and businesses.
Detailed inormation about cloud computing is not published any where as research work is still going on.
