.Net web apps hosted in the Azure cloud

Update: 08 Oct 2012 I discovered that Azure will not allow usage caps, so I have discontinued my subscription in order to prevent excessive charges. I’ve left this post here for historical reasons. I may explore other hosting alternatives in the future

I’ve recently switched over two of my demo web apps I wrote some years ago into the Microsoft’s Azure cloud service, something that greatly simplifies deployment and reduces my web hosting costs.

The first is No longer active, see beginning of post My remote control demo application which was an exercise to show an example of the command pattern

More sophisticated is my blackjack game, No longer active, see beginning of post which in a previous post in I showed its design.

Given that I wrote these programs in 2009, I certainly would not implement them again in the same way, as I was using some old technologies that have since been superseded (web forms, Linq to Sql) and my code would this time around implement SOLID principles.

Having previously set up and deployed Ruby on Rails websites on the excellent Heroku platform, in comparison Azure requires much less initial set up. Azure being built into Visual Studios means the developer is shielded from the complexities of deployment.

Counting in Heroku’s favour is the deployment speed; simple Azure apps take at least seven minutes to deploy, compared to around 30 seconds for Heroku.

For example in Ruby On Rails once you have set up the rake file to deploy locally, you can make a few alterations to that file for production setting and then run it on the Heroku instance in exactly the same manner as deploying locally.
Azure invents a brand new deployment work flow for the local copy of the cloud, which feels alien.

However I’m somewhat comparing apples to oranges, but I thought I’d share my insights. As a platform I’ll now be using Azure over independent web hosting.

One minor gripe when migrating data from a non-azure database to an Azure database was being forced to create clustered indexes which were not necessary in the original database.

Blackjack Web Application

This post will explain how how I created a blackjack simulator web application, in

Here is a demo site which you can try yourself

Look and feel is basic, but the demo remembers your user details and playing history upon registration.

Enjoy playing and feel free to post any feedback via the comments below.

My subversion repository hosts the project files containing the data classes, which build the BlackJackClasses.dll file . This file is referenced by Asp.Net Website Code which can be found here

To build the project from the source you will need Visual Studios 2008 IDE and access to a SQL Server database. As the user data is persisted to a SQL Server database you will need to run this SQL script on your database to create the required tables.

Compile the BlackJackClasses project first as this file handles game logic and database access.
You may wish to run Nunit unit and integration tests that I wrote for this project, which are in my subversion repository

You will need to add the dmbl file to this project to access the database via LINQ. Name this file DBBlackJack.dbml. Connect to your database and add the three new tables to the dbml file.

Once compiled, open the Web project, and add a reference to the dll the BlackJackClasses project has generated. You web project should now open.
The subversion repository can be found here
