Using Amazon S3 Object Lambda, you can add your own code to S3 GET, HEAD, and LIST API requests to modify data as it is returned to an application. You can now use an S3 Object Lambda Access Point alias as an origin for your Amazon CloudFront distribution to tailor or customize data to end users. For example, you can resize an image depending on the device that an end user is visiting from.

Beginning now, S3 Object Lambda Access Point aliases are automatically generated and are interchangeable with S3 bucket names for data accessed through S3 Object Lambda. For existing S3 Object Lambda Access Points, aliases are automatically assigned and ready for use. With aliases for S3 Object Lambda Access Points, any application that requires an S3 bucket name can easily present different views of data depending on the requester.

Aliases for S3 Object Lambda Access Points are available in all AWS Regions, excluding the AWS GovCloud (US) Regions. You can get started with S3 Object Lambda through the AWS Management Console, AWS Command Line Interface (CLI), Application Programming Interface (API), or AWS Software Development Kit (SDK) client.
