An alternative to installing the software on your physical hardware is to use Cloud-based services. Cloud services such as AWS (Amazon Web Services) and Azure from Microsoft provide an extremely agile and versatile environment to provision servers on demand at a cost of a few cents to a few dollars per hour of usage. While cloud installation is beyond the scope of this book, it is very simple to create a free AWS Account and use the same to install the different pieces of analytics software discussed in this book. Note that if you are using AWS/Azure or any of the other cloud services, you'll need to use the Docker version of Cloudera Hadoop distribution.
