Requirements

  • Basic programming knowledge (variables, functions, conditionals, JSON)
  • Basic understanding of web applications (HTTP requests/responses, client/server)
  • An AWS Free Tier account
  • A code editor such as VS Code

Description

Learn how to build, secure, and deploy modern serverless applications on AWS without managing a single server. You'll write APIs, process requests with AWS Lambda, persist data in DynamoDB, expose endpoints through API Gateway, and ship complete cloud applications using infrastructure-as-code and AWS best practices.

The course is hands-on first: every concept is reinforced with a console walkthrough, a coding exercise, or a lab, and the back half is built around full projects you can put on a résumé or GitHub.

What you'll build

  • A series of standalone Lambda functions (greeting, random-quote API)
  • A REST Notes API (full CRUD) backed by DynamoDB
  • A Product Catalog backend with query patterns
  • A complete, secured Task Management API
  • A production-style Serverless Todo App deployed via AWS SAM
  • Five bonus mini-projects (URL Shortener, Feedback Collector, Movie Reviews, Book Manager, Expense Tracker)

Standardized tooling

To keep everything consistent and reproducible, the course standardizes on Node.js 20 (LTS), JavaScript (ES2022 with async/await), the us-east-1 region, AWS SDK for JavaScript v3, and AWS SAM for infrastructure-as-code. Every lab ends with a cleanup step and a Free-Tier watch so you never get a surprise bill.

Who it's for

AWS beginners, developers new to cloud computing, students learning backend development, and anyone interested in serverless architecture. You need only basic programming knowledge, a rough understanding of how web apps work, and an AWS Free Tier account.

Mixed feelings — some lessons were excellent, others felt thin. Average overall.
