In this tutorial, we will use S3 Object Lambda to add a watermark to an image as it is retrieved from Amazon S3. ![]() ![]() In certain cases, images may need to be modified to include a watermark depending on the user accessing the image (for example, a paying subscriber can view images without watermarks, while a non-paying user receives a watermarked image). Many organizations store images in Amazon S3 that are accessed by different applications, each with unique data format requirements. The purpose of this tutorial is to show you how to get started with Amazon S3 Object Lambda. You can also use S3 Object Lambda to modify the output of S3 LIST requests to create a custom view of objects in a bucket, and S3 HEAD requests to modify object metadata like object name and size. You can use custom code to modify the data returned by S3 GET requests to convert data formats (for example, XML to JSON), dynamically resize images, redact confidential data, and much more. With Amazon S3 Object Lambda, you can add your own code to S3 GET, HEAD, and LIST requests to modify data as it is returned to an application.
