Recent Trends Of Big Data Platforms And Applications

Big data refers to large amounts of data beyond acceptable limits of commonly-used data collection, storage, management, and analysis software. Big data has become a new trend and culture in academia and industry from the beginning of this decade. The importance of big data technology is being widely recognized and getting higher owing to recent technology development. In particular, popular social media services as well as devices connected via Internet-of-Things are accelerating generation of big data. Then, the cloud service improves accessibility of such big data by allowing us to access it everywhere. Furthermore, computing power has also improved rapidly with the introduction of new CPU and GPU hardware technologies. On the basis of these environmental changes, MapReduce and Hadoop significantly contributed to making big data processing prevalent in these days. Hadoop, which is an open-source implementation of MapReduce, enables us to achieve high-performance computing with only commodity machines, but without requiring expensive mainframe computers.
