Walrus is primarily a storage platform and not suited for backend processing. For backend server deployment, you'll need a separate server as Walrus doesn't handle processing tasks, it's more for static storage. You could use Walrus effectively for frontend deployment if it involves decentralized apps where processing is mostly handled by smart contracts, but for backend, connecting it to a typical server provider would be necessary.

Consider deploying your backend on a standard server provider, which can work harmoniously with Walrus for the frontend. This way, you get the best out of both services.
