(T.Bourgeois, 2014) Every computer has access to Internet can receive software delivery from cloud computing.The NIST definition lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service.(NIST, 2011) T.Bourgeois claims that in post-PC world, limited storage and processing power of PCs were going to be replaced by cloud computing, which is able to storage, share and backup of information on huge scales. (2014) Nowadays, cloud has infiltrated most people’s life even without notices.
