In this hour you learned about the various approaches to deploying a Hadoop cluster including the Apache releases, commercial distributions and cloud deployment options. Commercial distributions are often the best approach to deploying Hadoop on premise in most organizations as these distributions provide a stable, tested combination of core and ecosystem releases, as well as typically providing a suite of management capabilities useful for deploying and managing Hadoop clusters at scale.
You also learned how to provision Hadoop clusters in the cloud by using the Amazon Web Services Hadoop-as-a-Service offering—Elastic MapReduce (EMR). You are encouraged to explore all the options available to deploy Hadoop. As you progress through the book you will be performing hands-on exercises using Hadoop, so you will need to have a functional cluster. This could be one of the sandbox or quickstart commercial offerings or the Apache Hadoop cluster we set up in the Try it Yourself exercise in this hour.
