Rdfe is related to Azure many times in this document, but I don't know what it means. I searched the internet and accidentally found a good article about Windows azure. The reason for this is that "there is a picture and a truth" and there is little nonsense. From the user's perspective, we have introduced how Windows azure responds to users' requests. Recommended here-Windows azure role
Architecture.
So what is rdfe? Reddog front end, reddog is the initial internal development code (codename) of Windows azure ). Rdfe is officially called Windows azure portal, which is the frontend of the entire windows azure service. In addition to providing deployment services, rdfe also provides subpartition management, billing, user access, and
Service management. It provides a set of rest interfaces for Windows azure portal to catch other tools, such as Visual Studio. Previously, it was also called the live portal service.
