The two options are a custom server that uses the PDFNet SDK on the server side to convert documents to web optimized files that WebViewer can view quickly on any device and browser, and WebViewer Server, which automates much of this process for you and is simplest to deploy but with a bit less control.
WebViewer Server is an optional drop-in backend for WebViewer that offers responsive viewing and compatibility across all client platforms (including mobile), along with scaling performance that approaches purely client-side solutions. It works hand-in-hand with WebViewer on the client, initially serving images then transitioning to client-side rendering.
See the WebViewer Server guide for more information.
If you don't want to use WebViewer Server as your document backend you can setup your own server to handle document viewing with WebViewer.
By converting a wide range of document formats into a web optimized XPS file, called XOD, WebViewer is able to deliver consistent results in viewing different document types.
