Google, for example, bundles a range of business services under the banner Google Apps. This development is enabled by agreed standards for software services The term Cloud Computing is used to represent distributed computing as an utility. A cloud forms a blanket over a set a Internet based application, storage, and computing services enough to support most users’ needs.

When the log becomes too large a checkpoint is created on the data in the main-memory so that it can be immediately restored back in the main-memory. Consequently, the I/O of the GFS cluster is reduced significantly. This organization allows a single master to control a few hundred chunk servers, which is a considerable size for a single cluster. By subsequently organizing a service such as Google into smaller services that are mapped onto clusters, it is not hard to imagine that a huge collection of clusters can be made to work together.
For example, it is convenient for users to control their wash- 26 1 Introduction ing machines or their entertainment systems from their phones.
