Unity, the company behind the popular real-time 3D engine, today officially launched its Cloud Content Delivery service. This new service, which is engine-agnostic, combines a content delivery network and backend-as-a-service platform to help developers distribute and update their games. The idea here is to offer Unity developers — and those using other game engines — a live game service option that helps them get the right content to their players at the right time.

As Unity’s Felix The noted, most game developers currently use a standard CDN provider, but that means they must also develop their own last-mile delivery service in order to be able to make their install and update process more dynamic and configurable. Or, as most gamers can attest, the developers simply opt to ship the game as a large binary and with every update, the user has to download that massive file again.
