Amazon Simple Notification Service (Amazon SNS) is a fully-managed, high-throughput, pub/sub messaging service from AWS. It's used for sending messages to applications and people. It's often used as the backbone of flows that involve disparate AWS services, applications, and users.

Developers and Engineers aiming to get AWS certified should be comfortable creating, developing, and configuring solutions built around Amazon SNS. This challenge will also test your knowledge of Amazon S3 and AWS Lambda.

In this lab challenge, you will be tested on your practical ability to build out a solution in a production-like AWS environment. You are presented with a task and a set of requirements that you must fulfill to pass the challenge. This is a real environment, which means you can prove your knowledge in an applied situation, leaving behind multiple choice questions for a dynamic performance-based exam situation.
