Background: Amazon Web Services (AWS) offers a large variety of products and for many of us coming from traditional on-premises environments it can be easy to get confused with the terminology. My goal here is to give a brief description of the AWS services (as of June 2016) and identify their on-prem equivalents (or best match in my opinion). Please feel free to comment if you see any areas that can use clarification. This is a list for my personal supplement and is not meant to be an authoritative or all-encompassing resource. All information was obtained from the AWS Documentation site, which you can visit at aws.amazon.com/documentation.
