Cloud Computing-Software as Service
Cloud Computing, to put it simply, means "Internet Computing." The Internet is commonly visualized as clouds; hence the term "Cloud computing" for computation done through the Internet. With Cloud Computing users can access database resources via the Internet from anywhere, for as long as they need, without worrying about any maintenance or management of actual resources. Besides, databases in cloud are very dynamic and scalable. Cloud computing is unlike grid computing, utility computing, or autonomic computing. In fact, it is a very independent platform in terms of computing.
