 # What is Azure HDInsight?
 
-Azure HDInsight is a managed, full-spectrum, open-source analytics service in the cloud for enterprises. With HDInsight, you can use open-source frameworks such as Hadoop, Apache Spark, Apache Hive, LLAP, Apache Kafka, Apache Storm, and more, in your Azure environment.

 ## What is HDInsight and the Hadoop technology stack?
 
-Azure HDInsight is a cloud distribution of Hadoop components. Azure HDInsight makes it easy, fast, and cost-effective to process massive amounts of data in a customizable environment. You can use the most popular open-source frameworks such as Hadoop, Spark, Hive, LLAP, Kafka, Storm and more. With these frameworks, you can enable a broad range of scenarios such as extract, transform, and load (ETL), data warehousing, machine learning, and IoT.

 To see available Hadoop technology stack components on HDInsight, see [Components and versions available with HDInsight](./hdinsight-component-versioning.md). To read more about Hadoop in HDInsight, see the [Azure features page for HDInsight](https://azure.microsoft.com/services/hdinsight/).
 
 ## Why should I use Azure HDInsight?
 
 |Capability  |Description  |
 |---------|---------|
-|Cloud native     |     Azure HDInsight enables you to create optimized clusters for Hadoop, Spark, [Interactive query (LLAP)](./interactive-query/apache-interactive-query-get-started.md), Kafka, Storm, HBase on Azure. HDInsight also provides an end-to-end SLA on all your production workloads.  |

 |Low-cost and scalable     | HDInsight enables you to scale workloads up or down. You can reduce costs by creating clusters on demand and paying only for what you use. You can also build data pipelines to operationalize your jobs. Decoupled compute and storage provide better performance and flexibility. |
 |Secure and compliant    | HDInsight enables you to protect your enterprise data assets with Azure Virtual Network, encryption, and integration with Azure Active Directory. HDInsight also meets the most popular industry and government compliance standards.        |
 |Monitoring    | Azure HDInsight integrates with Azure Monitor logs to provide a single interface with which you can monitor all your clusters.        |
 |Global availability | HDInsight is available in more regions than any other [big data](#what-is-big-data) analytics offering. Azure HDInsight is also available in Azure Government, China, and Germany, which allows you to meet your enterprise needs in key sovereign areas. |  
-|Productivity     |  Azure HDInsight enables you to use rich productive tools for Hadoop and Spark with your preferred development environments. These development environments include  Visual Studio, VSCode, Eclipse, and IntelliJ for Scala, Python, Java, and .NET support. Data scientists can also collaborate using popular notebooks such as Jupyter and Zeppelin.    |

 |Extensibility     |  You can extend the HDInsight clusters with installed components (Hue, Presto, and so on) by using script actions, by adding edge nodes, or by integrating with other [big data](#what-is-big-data) certified applications. HDInsight enables seamless integration with the most popular [big data](#what-is-big-data) solutions with a one-click deployment.|
