Explain what is AutoScaling?

Scaling by adding additional instances is often referred to as scaling out. Windows Azure also supports scaling up by using larger role instances instead of more role instances.
By adding and removing role instances to your Windows Azure application while it is running, you can balance the performance of the application against its running costs.
An auto-scaling solution reduces the amount of manual work involved in dynamically scaling an application.

What is the difference between Web and Worker Roles in Windows Azure?

As you know the main difference between the two is that an instance of a web role runs IIS, while an instance of a worker role does not. Both are managed in the same way, however, and it’s common for an application to use both.For example, a web role instance might accept requests from users, then pass them to a worker role instance for processing.

Explain what is Azure Blob?

Azure Blob storage is a service for storing large amounts of unstructured object data, such as text or binary data, that can be accessed from anywhere in the world via HTTP or HTTPS. You can use Blob storage to expose data publicly to the world, or to store application data privately.
