These transactions are recorded in the general journal first, and typically include more information than is included in the accounting ledger; the balance of each account is not included. As in the accounting ledger, however, the credits and debits listed in the general journal must total zero.
Grid Computing is a form of distributed system with non-interactive workloads. Utility Computing is a business model where computing resources are metered. Cloud Computing is a form of utility computing that allows developers to develop, deploy and run applications.
In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing system's interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest. There's a good chance you've already used some form of cloud computing.
