The serverless approach allows your application to use a presigned URL and upload directly to Amazon S3. This offloads all the bandwidth and compute requirements away from your application, and instead relies on the massive scalability of S3.
This walkthrough shows how to implement an uploading solution for a broader application. You can use this method in any type of web application, even ones that are not serverless. It’s a simple example you can easily extend for your own needs. All the code is available in a GitHub repo.
This series is about the S3-to-Lambda serverless design pattern, and how it can become a flexible core for your serverless applications. To learn more, see the other videos in this series.
