AWS S3 contd

• AWS S3 recommends not to use ACL’s
• I want to give an access of an object temporarily to someone we can use presigned urls for temporary access
• I want to give access to public: use policy generator for creating public access to your bucket. (Watch classroom video)

      "Principal": "*",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::lts3-confidential/*"
    }
  ]
}

• I want to give permission to a specific user (aws) to do anything in my bucket

• AWS offers CDN as a service using AWS Cloudfront
