Microsoft previously announced a new Azure Data Lake service that would provide the repository for massively scalable big data storage. The service has been refined and expanded to now include:
Azure Data Lake Store: what was previously announced as Azure Data Lake, provides a massively scalable repository for capturing data built on HDFS.
Azure Data Lake Analytics: a new service built on Apache YARN for performing distributed analytics.
Azure HD Insight: full managed Hadoop clusters, now available on Linux as well as Windows.
