Requirement: Manually upload a file on to S3 bucket on Amazon Web Services.
First, use your user name and password to log into the website https://til-internal-ds.signin.aws.amazon.com/console
Then, go to S3 bucket and find a bucket name if it has been existed or you can create a bucket. Here, the bucket name I used is ds-snowflake-stage.
Next, click upload a file and click add a file on the pop up window. Choose the file you would like to upload. Once it's successfully uploaded , you can hit close.
The file will appear on the stage area.
