Build a Self-Scaling Serverless API on AWS

This course walks you through building a serverless REST API on AWS — one that scales from your first request to millions without you touching the infrastructure.

You'll define the entire stack as Infrastructure as Code with AWS CDK, so every resource is versioned, repeatable, and easy to tear down when you're done. By the end you'll have a working project with:

• A REST API exposed through AWS API Gateway

• Lambda functions handling each route, scaling on demand

• A DynamoDB table for storage, with no servers to manage

• A CDK codebase you can fork and extend for your own ideas

Why this stack

Serverless on AWS gives you something traditional servers can't: you pay only for what you use, and the platform handles the scaling for you. If a side project suddenly takes off, the API keeps responding while you sleep. If nobody touches it for a month, the bill stays near zero.

CDK is what ties it together. Instead of clicking through the AWS console or writing thousands of lines of CloudFormation YAML, you describe your infrastructure in TypeScript and let CDK generate the deployment.

What you should already know

Some JavaScript or TypeScript, and a rough sense of how HTTP and cloud services work. You don't need prior AWS experience — we'll set up the account and tools together in the first lessons.

What this course doesn't cover

This isn't a deep dive into IAM hardening, VPC networking, or multi-region failover. The goal is to get you fluent with the core serverless pattern. Once you have that, the rest is much easier to pick up on your own.
