Pre-signed URLs
Why use a pre-signed URL for client uploads to object storage instead of proxying the bytes through your API?
Options
- 1It encrypts the object at rest with a key that the client never has to manage, rotate, or even store anywhere
- 2It lets the client upload directly to the storage service with a time-limited signed credential, offloading bandwidth from your app servers
- 3It removes the need for any authentication because the object store simply trusts the originating client IP address
- 4It makes uploads strongly consistent, so a read immediately after the write always observes the newly uploaded object
