Publish to local file system then upload it by hand or with a tool like https://rclone.org/
Publish to github and use github actions to upload (there are probably actions for that in github marketplace
Contribute an AWS service to https://github.com/silexlabs/unifile - this is my favorite option of course, you need to know nodejs but it should not be a lot of work, let me know if you need pointers
I have to publish the page using EC2 instance. Do we have any link related with that?
