An architecture emerged: massively scaled, (73) distributed system resources,abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on (74)“somewhere on the Intemet”and the application runs on both the "cloud servers”and the user's browser.Both clouds and grids are built to scale horizontally very efficiently. Both are built towithstand failures of (75) elements or nodes. Both are charged on a per-use basis.
