I created this proposed architectural diagram as a starting point to developing a highly scalable and flexible technology stack that can be run on your own hardware or on cloud based infrastructure providers. All coding for application built for this stack is done in C#, from mobile apps running on 3 different platforms to the web apps / web services. This still needs a lot more research but I would like to get some feedback on how well this stack would forefill the requirements of needing to be highly scalable and where applications developed to run on it can be written in a single language, namely C#. References to the various technologies are shown below.
