Here's a quick AWS Lambda in Java tutorial to quickly get you started with AWS functions.
In this example we keep it super simple. We create a simple class with a simple method and don't import any Maven projects and we don't use any special AWS libraries. Just a simple method, packaged in a JAR and exported from Eclipse.
Then we upload that to the AWS Lambda page, edit the runtime with the class and package name, and then test.
Voila! A simple Java AWS Lambda function deployed in less than 5 minutes. It's pretty spectacular!
