By using data storage based on cloud computing, business owners can leverage more attractive prices and consistently reduced costs while integrating a variety of new features from different vendors. Cloud services, as cloud computing or cloud storage, can be valuable assets for cost-sensitive SMEs. Although some of the larger organizations have the resources to build their own cloud storage services, small and medium-size enterprises often need to turn to some cloud storage providers for Internet-accessible storage ...

The public cloud not only changes the price structure of computing and storage, but it also expands the scope of what enterprise it can do. This is especially true when working with large datasets, where there is no practice for flexible computing and storage access. The loose definition of "big Data" is a dataset that is too large to be processed with traditional data management techniques and infrastructure. Detailed server logs, click Stream data, social network data, and mobile device data are complementary to transactional data types in the Data warehouse and in business intelligence systems. In addition, the public cloud data repository and Third-party accelerators also provide large data set topics from T ...
