AWS is one of the most popular cloud platforms. Check a detailed post on AWS S3 here:

Creating a sharable link in MuleSoft:

• We set the bucket name
• We set the key of the object/file we want to share
• We set the time till which the url is suppose to be active
• We use the S3 Create object presigned uri operation to generate shareable url
  
• We Transform the message to show output
  

The payload will have the presigned URL
