    Thank Vijay so much for your great explanation. I followed your steps to enable the CORS for the bucket, and still got an error like below, wish you can give me some hints, thanks.

    Access to XMLHttpRequest at '' from origin '' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    Superb teaching technique for AWS development. I like your way of teaching. first only API gateway (get request) then add how API gateway and lambda function works and then add DB table and finally how API, LAMBDA, DB and static website works each other.

    Very nice clear, breif and precise. Most of the AWS tutorials start after 30-40Mins which is really annoying, but yours is completely straight to the point. Thank you very much. Subscribed.
