Start course
In this four week course, you’ll learn how to implement low-latency and streaming Big Data solutions using Hadoop technologies like HBase, Storm, and Spark on Microsoft Azure HDInsight.
Course SyllabusUse HBase to implement low-latency NoSQL data stores.
Use Storm to implement real-time streaming analytics solutions.
