 # Apache Hadoop architecture in HDInsight
 
 [Apache Hadoop](https://hadoop.apache.org/) includes two core components: the [Apache Hadoop Distributed File System (HDFS)](https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsUserGuide.html) that provides storage, and [Apache Hadoop Yet Another Resource Negotiator (YARN)](https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html) that provides processing. With storage and processing capabilities, a cluster becomes capable of running [MapReduce](https://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduceTutorial.html) programs to perform the desired data processing.
