With cloud computing growing day by day, the limits are really looking indefinite to its reach and potential. Cloud computing has applications run from the cloud or a collective of computer systems linked such as the internet. The program never resides on one specific system but is rather juggled around in cyberspace used by who ever wishes to or has access to it.
This being said, security is one of the major issues yet to be concretely solved for as secure as most are, applications such as social media(known as one of the most hacked form of application running on the net) are in a constant battle to keep legit users in and others out.
