Windows Azure: How-To Add Instance in Management Portal

In this article, I will show you how you can add/reduce instances for your Windows Azure application. You can also use the steps below to edit other configurations in your application. This is equivalent to editing the .csdef file in your source code solution from Visual Studio.

1. Login to the Windows Azure Management Portal using your Live ID at http://windows.azure.com/
2. Once you’re logged in, click on Hosted Services, Storage Accounts & CDN at the lower left of the page.
   
3. Next, click on your application where its type is Deployment.
4. At the ribbon on the centre top of your page, click on Configure.
   
5. Click on Edit Current Configuration in the pop-up window.
   
6. Now, look for the instance count tag that shows how many instance your application has and edit the number of instance count.
7. Finally, click OK and wait for the application to be updated.

Note: If you have at least one instance running, there will be no downtime to your application. So  you don’t have to worry that there is downtime while the updating be being executed.
