Implement a Serverless REST API with AWS Lambda and API Gateway

INTERMEDIATE
120 minutes
5 tasks

In this lab, you will implement a serverless RESTful API using AWS Lambda and Amazon API Gateway. You will learn how to configure Lambda functions with environment variables and IAM roles, integrate them with API Gateway for seamless HTTP requests handling, and configure API Gateway stages and routes. Additionally, you will set up DynamoDB as the backend database to store data managed by the API. The lab will help you understand the interplay of API Gateway and Lambda in building scalable web services with minimal infrastructure management.

Scenario

Your company, Tech Innovators, wants to launch a new feature allowing users to retrieve and manage their profiles via a REST API. The profiles should be stored in a highly available and scalable environment. Using a serverless architecture is preferred for cost efficiency and scalability.

Learning Objectives

  • Configure AWS Lambda functions with environment variables and IAM roles
  • Set up Amazon API Gateway to manage HTTP requests for the Lambda functions
  • Integrate DynamoDB as the database for storing profiles
  • Implement security controls for API access management
