S3 for Application Storage

This lab focuses on updating the application code developed for the grid-maker application. After testing the application to create a new grid image locally, you update the application code to use images stored in an Amazon Simple Storage Service (Amazon S3) bucket instead. You verify the functionality of the application by accessing images stored in an S3 bucket, creating a new grid image, and generating an S3 presigned URL to view the grid image that gets stored in a separate S3 bucket.
