You need an active AWS account. You need to follow the section Getting started in the recipes Your first AWS Lambda and Your first Lambda with AWS CLI from Chapter 1, Getting Started with Serverless Computing on AWS to set up Java, Maven, the parent project, serverless-cookbook-parent-aws-java, and AWS CLI, and may also read other notes there including code usage guidelines, S3 bucket creation, and notes for Windows users.

A basic understanding of HTTP, REST, Java, and Maven is required to understand and follow the steps within this recipe. Knowledge of a REST client, such as Postman, is also good to have. You can refer to the previous recipes if you do not have the required basic understanding of these technologies and/or tools.
