Amazon S3 Object Lambda is now available in the Asia Pacific (Osaka) AWS Region. With S3 Object Lambda, you can add your own code to S3 GET, HEAD, and LIST requests to modify and process data as it is returned to an application. You can use custom code to modify the data returned by S3 GET requests to filter rows, dynamically resize images, redact confidential data, and much more. 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.
