Big Data Analysis is computation of real-time large-scale data across multiple sources. learn-it-hadoopSo it is an expensive and time consuming business. Instantaneous analysis of big data on a cluster of computers across multiple sources can be easily done on a platform like Hadoop. Hadoop as an open source program was launched by Yahoo in 2008. However, Hadoop’s framework and ecosystem of technologies was later endorsed by Apache Software Foundation. By 2013, Hadoop became the tool more than half of the Fortune 50 companies who use it for production and research using large-scale data across a grid of computers functioning on single servers to thousands of machines. Hadoop has been designed towards auto-detection and auto-handling of failures in any system functioning in its framework. With constantly growing social media data, Hadoop is the key resource to massive storage and fast processing of enormous data, both onsite data center and cloud storage. Today Hadoop being the main tool for Big Data handling and analysis, Hadoop-Big Data training are interrelated concepts.Companies offering cloud storage using Hadoop are Microsoft, Amazon, IBM, Google, ORACLE.
