In its widest usage, Cloud Computing is the delivery of scalable information technology over the Internet as opposed to operating and hosting those resources locally such as university or college network. As an alternative of keeping data on a hard drive or application updates needed, cloud computing is a convenient service over the Internet at another location to store information or use its application. It allows individuals to use software and hardware managed by third parties at remote places.
