Moving our MVC app to the cloud Creating a “Cloud Project” At this point we have a running on-premise MVC application that gets data from SQL Azure (cloud based relational storage).Here is what this blog post will cover New Azure Project Adding an "MVC 2 Web Role" Understanding Instance Count and VM Size Connecting our new Cloud Project to the DataLayer Changing the .NET Framework version for the DataLayer Implementing the Connection String

Windows Azure Project  Note the Cloud templateSelect the Windows Azure Cloud Service.

Choosing a web role  Select MVC Web roleFor the post, we are talking about MVC Web Role.

Naming your web role  Changing the default nameClick on the icon of the pencil to change the name of the web role. We will name our web role as MvcAzure_WebRole

Unit Tests Unit tests have value, but are beyond the scope of this post Unit testing is a software verification and validation method in which a programmer tests if individual units of source code are fit for use A unit is the smallest testable part of an application For MVC apps, a unit may be an individual function or procedure Unit tests are typically written and run by software developers to ensure that code meets its design and behaves as intended

Not one, but 2 projects have been added  Why 2 projects? The first project (MvcAzure) is your configuration project. More on this later. The second project is the Azure-based MVC project. We will make our modifications to the code base here in MvcAzure_WebRole.

How to configure your Azure MVC Application Double-click on “MvcAzure_WebRole” In order to change the configuration of your application, double-click on MvcAzure_WebRole

Instance Count & VM Size  Changing Configuration settingsDouble clicking on MvcAzure_WebRole brings up the configuration windows you see below.

A note about limits  Understanding VM Size and Instance Count The number of CPU cores for a role is the Instance Count If you add those up across all of your roles across all of your Hosted Service projects (staging and production slots) – this has to be lower than 20 Quick example: if you have 5 Hosted Service projects with 1 role, 2 instances per role and Medium VM size, you’ve hit the limit The other key is that you not only need to stop your deployment to free up CPU cores, you also need to delete the deployment to reduce your CPU core count You can read more about this here:https://azurefeeds.com/post/900/Windows_Azure_Instance__Storage_Limits.aspx

Setting up references – same as before  MvcAzure_WebRoleThis exact process was performed for the on-premise MVC application.

The DataLayer needs to be built upon version 3.5 of the .NET Framework  Azure only supports version 3.5 currentlyThe upgrade to 4.0 of the .NET Framework will happen any day now. In the meantime, you’ll need to “downgrade” to version 3.5.

Still need to add a reference for System.Data.Entity  Right mouse click on MvcAzure_WebRoleAdd a reference and then be prepared to “Copy Local”

  

Managing Connection Strings  Copy the connection string to MvcAzure_WebRoleWe did this exact step in a previous post: https://blogs.msdn.com/b/brunoterkaly/archive/2010/06/11/creating-an-on-premise-database-and-mvc-web-application-and-migrating-to-windows-azure-and-sql-azure.aspx
