INTERMEDIATE
120 minutes
5 tasks

This lab guides you through building a serverless image processing application using AWS Lambda, Amazon S3, Amazon API Gateway, and AWS Step Functions. You'll create an API to upload images, process them for thumbnails using Lambda functions, and manage workflows with Step Functions. This hands-on practice will enhance your skills in serverless architecture design, integration of AWS services, and deployment of applications without managing infrastructure.

Scenario

A startup company called ImageX needs a scalable and cost-efficient solution to allow users to upload images and receive processed thumbnails quickly. The company wants to leverage AWS serverless technologies to minimize infrastructure overhead and optimize costs. Your task is to design a workflow that manages image uploads, processing, and delivery of thumbnail images using AWS services.

Learning Objectives

  • Implement a serverless API using AWS API Gateway
  • Automate image processing with AWS Lambda functions
  • Manage workflows with AWS Step Functions
