S3 Object Lambda tutorials

The following tutorials present complete end-to-end procedures for some S3 Object Lambda tasks.

With S3 Object Lambda, you can add your own code to process data retrieved from S3 before returning it to an application. Each of the following tutorials will modify data as it is retrieved from Amazon S3, without changing the existing object or maintaining multiple copies of the data. The first tutorial will walk through how to add an Amazon Lambda function to a S3 GET request to modify an object retrieved from S3. The second tutorial demonstrates how to use a prebuilt Lambda function powered by Amazon Comprehend to protect personally identifiable information (PII) retrieved from S3 before returning it to an application. The third tutorial uses S3 Object Lambda to add a watermark to an image as it is retrieved from Amazon S3.
