Why should I care?

You should care about pre-signed GET and POST for Digital Ocean Spaces because it allows you to securely grant temporary access to private resources without giving full access to your users. This is useful in situations where you want to allow users to download or upload files to your Digital Ocean Space without exposing your entire storage system.

It helps protect your resources from unauthorized access and potential security threats like link sharing and replay attacks. This technique is particularly important for applications that require user-generated content or file sharing, ensuring that your system remains secure while still being user-friendly.

The request also goes directly from client/frontend to the storage server bypassing the web application server in the hot path. Typically the web application server can respond to web hooks after successful client uploads into the storage server backend.
