Simple 5 steps to run your first Azure program

Step 1:-
Ensure that you have the proper OS and VS edition.

Step 2:- Download the Windows
Azure SDK

Step 3:- Download Windows Azure

Step 4:-
Create the project

5:- Run your application


In this article we will look in to 5 basic steps which will help us to run our
first azure program. In this article we will understand how to create a simple
web role application and while doing the same we will understand some
development concepts of Azure.

If you are really lazy like me you can download my two azure basic videos which
explain what azure is all about Video1
, Video2.

Please feel free to download my free 500 question and answer eBook which covers
.NET , ASP.NET , SQL Server , WCF , WPF , WWF@ .

So let’s start with the 5 basic steps. By the way when I wrote this article it
was 31st December, 10:30 evening, so Happy New Year and blast yourself. Do not
drink and drive , just drink , drink and sleep.

Step 1:-
Ensure that you have the proper OS and VS edition.

Windows azure works only on Windows 7, Windows
Server 2008 and Windows Vista. It does not work on XP currently. So ensure you
have one of the above mentioned operating system. Developers who are on XP do
not attempt it, I have tried heavily but there is no way currently to execute
Azure on XP. There are lot of hack which are given online, believe me none of
them work.

From visual studio aspect ensure you have VS 2008 or VS 2010.

Step 2:- Download the Windows
Azure SDK

Windows Azure SDK simulates Azure hosting
environment in your PC, so that you can develop your applications locally and
then upload the online. So the first step is to download the SDK.

Once you install Windows Azure you should see two menus one of the development
fabric and the other of the development storage.

You can also see the fabric and storage running
on your task bar.

If you click on the same you should be able to
see the fabric and storage as seen in the below figure.

Step 3:- Download Windows Azure

We will need the cloud service visual studio
template to speed up development in visual. So click on the below link to
download windows azure tools which will install the template in visual studio.

If windows azure tool is successfully installed you should get the cloud service
template as shown in the below figure.

Step 4:-
Create the project

Once you have the cloud service template in
your visual studio environment, click on it and select the ‘Web role’ as shown
in the below figure. There are two kinds of basic applications you can create on
azure ‘Web role’ and ‘Worker role’. Web role are nothing but web application
while worker roles are back ground processing applications like windows

To keep it simple we have currently selected ‘WebRole’.

Once you are done you should get two projects
as shown below. Once project is the cloud service project and the other is your
web application. Cloud service project has associations to web and worker role

The cloud service has two files
‘ServiceConfiguration.cscfg’ and ‘ServiceDefinition.csdef’.

The ‘ServiceDefinition.csdef’ file contains the metadata needed by the Windows
Azure fabric as per your application needs. It will also contain configuration
settings that apply to all instances. .

The ‘ServiceConfiguration.cscfg’ file lets you set the values for the
configuration settings and the number of instances to run for each role. So you
can define some parameter called as ‘ConnectionString’ in your definition file
and set the value in the configuration file.

5:- Run your application

In order to keep this simple just run the
project as it is. Your application will run as shown in the below browser and at
the back ground fabric will create virtual instance in which your application
runs. The below figure shows the virtual instance created by fabric to run your

In order to understand the power of azure
configuration, go to the service configuration file and change the instance to
2, you should see two instances of your web role running as shown below.
