Cloudera Inc. is a Palo Alto-based enterprise software company that provides Apache Hadoop-based software, support and services, and training to data driven enterprises. Cloudera's open-source Apache Hadoop distribution, CDH (Cloudera Distribution Including Apache Hadoop), targets enterprise-class deployments of that technology. Cloudera says that more than 50% of its engineering output is donated upstream to the various Apache-licensed open source projects (Apache Hive, Apache Avro, Apache HBase, and so on) that combine to form the Hadoop platform. Cloudera is also a sponsor of the Apache Software Foundation. The preferred demonym for an employee of Cloudera is 'Clouderan.' The launch of Cloudera was announced by the New York Times, which called Cloudera 'the quintessential Silicon Valley story'.
