There's no AWS service that does this, but you can set something up using Lambda, API Gateway, and S3. There's an example repo at https://github.com/awslabs/serverless-image-resizing

It will be different: Aliyun gives you transcoding/resizing on every CDN endpoint (which they have many) vs resizing in DC

Could potentially do it with Lambda@Edge

If you can resize in under 50ms with less than 128mb RAM usages, maybe. With the current constraints JSON and text transforms are more feasible.

Alternatively, you can use a 3rd party image engine on AWS: https://aws.amazon.com/marketplace/pp/B019YEIK7M?qid=1500045...

It should be a lot faster.
