CDN or Content Delivery Network is a system of servers deployed in multiple data centers across the world. When someone pulls a file from CDN, that file is transferred to a client device via a server closest to the location of that client, which is way faster than using a route to some remote machine. Also, your file is cached on multiple servers. Hence you always get a better uptime.
Uploadcare features a powerful and secure CDN that delivers your files across the world, fast. Once you upload a file via our widget or APIs, you get a CDN link holding your file UUID. Here’s how it usually looks like:
Every file you upload seamlessly goes to our CDN, and the link you get is then used to access it. Identifiers act as file entities on our system: every action is performed using file UUIDs. That’s the default behavior when using the Uploadcare storage.
