Users don’t purchasesoftware, but rather access the applicationon a subscription basis (or free in somecircumstances). (Example: SalesForce.com)Provides an application platform as a servicefrom which software engineers can develop,test, and deploy applications quickly andefficiently.

Going with a cloudsolution means buying into the specific protocols, standardsand tools of the cloud vendor, making future migrationcostly and difficult. How is this so? Because standards arestill being formed, and cloud computing is still too immatureto reach the point where customers are demanding vendori dindependence.dThThe problembliis, whenh companiesi sitit ddownto calculate the cost of using cloud computing services,they don’t factor in the costs of migrating off the system –expenses which could be prohibitive and unexpected.”--Joe McKendrick (Forbes.com)9

Cloud Computing J.B.I.E.T Page 5 Computing Paradigm Distinctions . The high-technology community has argued for many years about the precise definitions of centralized computing, parallel computing, distributed computing, and cloud computing. In general, distributed computing is the opposite of centralized computing.
Mobile Cloud Computing Cloud Computing has been identified as the next generation’s computing infrastructure. Cloud Computing allows access to infrastructure, platforms, and software provided by cloud providers at low cost, in an on-demand fashion. Mobile Cloud Computing is introduced as an int

Cloud computing "Cloud computing is a computing paradigm shift where computing is moved away from personal computers or an individual application server to a "cloud" of computers. Users of the cloud only need to be concerned with the computing service being asked for, as the underlying details of how it is achieved are hidden.
The rationale of cloud computing (for the customer) is reduced and linearly scaling costs. Cloud computing allows allocating required computing resources dynamically to demand. It scales linearly with the number of users, i.e. incurs no or little capital expenses (capex), only operating expenses (opex). Traditional IT: Cloud computing: Users .
