Develop and Deploy a Serverless Web Application with AWS Lambda and API Gateway

INTERMEDIATE
135 minutes
5 tasks

In this lab, you will build a serverless web application using AWS Lambda and Amazon API Gateway. This application will leverage Amazon DynamoDB for persistent data storage and AWS Secrets Manager for secure handling of sensitive information. You will develop a Lambda function to handle HTTP requests routed through API Gateway, manipulate data in a DynamoDB table, and securely manage configuration data using Secrets Manager. This lab provides practical exposure to serverless architecture and managing application environments on AWS.

Scenario

You are a developer at Tech Solutions, an innovative company specializing in cloud-native applications. The team decided to migrate an existing microservice to a serverless architecture to improve scalability and reduce operational overhead. Your task is to develop and deploy a serverless application using AWS Lambda to process customer feedback forms sent via a web interface. This includes configuring API Gateway to handle incoming HTTP requests and using DynamoDB for data persistence.

Learning Objectives

  • Develop AWS Lambda functions to handle HTTP requests.
  • Configure Amazon API Gateway to interact with AWS Lambda.
  • Utilize Amazon DynamoDB for data storage.
  • Manage secrets securely using AWS Secrets Manager.
  • Deploy the serverless application within a budget.
