Cloud Computing Architecture: What Is Front-End and Back-End

In cloud architecture, the front-end/back-end distinction extends beyond a single application to the infrastructure layer itself. The front-end typically includes the user-facing interface plus edge services like CDNs that deliver content close to users. The back-end encompasses application servers, databases, and the cloud infrastructure services (compute, storage, networking) that support them.

Modern cloud architectures increasingly separate these concerns explicitly — a front-end deployed to a global CDN, communicating with back-end services running in managed compute environments, connected through well-defined APIs. This separation enables independent scaling: front-end assets scale through CDN edge caching essentially for free, while back-end compute scales based on actual processing demand.

Cantonet Technologies designs cloud architectures with this clean separation, ensuring each layer scales efficiently on its own terms.
