Azure Owin F-Sharp:
This is generic cloud based online collaboration/gaming platform. But because generic sounds bad, let's specify more:
This is a architecture of users (players) and rooms (games). Users can join rooms. They can chat with other users in the rooms. Users can co-operate with other room users, e.g. play games.
Claims based authentication: Facebook / Google+ (/...) external logins are supported
See the high level picture:
The whole system runs in cloud as Windows Azure Worker role. Worker role hosts OWIN (Katana) based web server. Web server hosts (Hateoas) REST-based WebApi for data communication. And SignalR (Hub) for web-based Publish/Subscribe -pattern to enable real-time bi-directional communication between users, usually based on WebSockets. Web server tunnel static HTML-files from Windows Azure Blob Storage.
User data is stored to Windows Azure Table Storage (which is a NoSQL document database).
Runtime data uses Actor/Agent -based communication: Each user has an agent. Each room has an agent. There is (generic strongly typed) control agent class which can create other agents. (e.g. one instance for room-agents, one for user-agents)
Programming language is F-Sharp (F#). It is a multi-paradigm (functional-first) programming language mainly for .NET environment. F# related technologies: Fog is used for Azure communication. FSharp.Net.Http and FSharp.Web.Http is used for HTTP communication.
This is developed with Visual Studio 2012 (Update 4) / Visual Studio 2013 and Azure SDK 2.2. References are resolved via NuGet.
To run:
Build and run from Visual Studio
See the host console from (task tray icon) Azure Compute Emulator.
There is a line something like: "Starting OWIN at http://127.255.0.0:81"
(If compute emulator logging works...)
Copy the address and open it with web browser.
(...or you can deploy this to Windows Azure)
Sample HTML-pages are just HTML5 with jQuery and Knockout.js They are deployed from the wwwroot.zip -file.
