What Is Apache Hadoop? The Apache   Hadoop project develops open-source software for reliable, scalable, distributed computing. The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures. The project includes these modules: ·          Hadoop Common : The common utilities that support the other Hadoop modules. ·          Hadoop Distributed File System (HDFS) : A distributed file system that provides high-thr...

Cloud computing Cloud computing is a type of computing that relies on   sharing computing resources  rather than having local servers or personal   devices   to handle   applications . Cloud computing is comparable to   grid computing , a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine. Internet-Based Computing In cloud computing, the word   cloud   (also phrased as "the cloud") is used as a metaphor for " the Internet ," so the phrase   cloud computing   means "a type of Internet-based computing," where different services   —   such as servers, storage and applications   —   are delivered to an organization's computers and devices through the Internet.   How Cloud Computing Works Cloud computing applies traditional   supercomputing , or   high-performance computing   power, norma...
