Summary

We live in a connected digital era and are witnessing unprecedented growth of data. Organizations that are able to analyze Big Data are demonstrating significant return on investment by detecting fraud, improved operations, and reduced time to analyze a scale-out architecture. Apache Hadoop is the leading open source big data platform with strong and diverse ecosystem projects that enable organizations to build a modern data architecture. At the core, Hadoop has two key components—Hadoop Distributed File System also known as HDFS and a cluster resource manager known as YARN. YARN has enabled Hadoop to be a true multiuse data platform that can handle batch processing, real-time streaming, interactive SQL, and others.

Microsoft HDInsight is an enterprise-ready distribution of Hadoop on the cloud that has been developed in partnership with Hortonworks and Microsoft. Key benefits of HDInsight include: scale up/down as required, analysis using Excel, connect on-premise Hadoop cluster with the cloud, and flexible programming and support for NoSQL transactional database.

In the next chapter, we will take a look at how to build an Enterprise Data Lake using HDInsight.
