Microsoft Azure - Interview Questions
What is Azure Cloud Service?
* Azure Cloud Service is a classic example of a platform as a service (PaaS). This was designed to support those applications which demand high scalability, reliability, and availability all within the constraints of reduced cost of operations. These are hosted on virtual VMs and Azure provides more control over them by letting the developers install the necessary software and enabling them to control remotely.

* Azure cloud services are used for deploying multi-tier web-based applications in Azure by means of creating an instance of cloud service. It is also possible to define multiple roles such as web roles, worker roles, etc for the purpose of distributed processing. Azure cloud services help in the easier and flexible scalability of the application.

* Each role of the cloud service has its own purpose and thereby its own configuration and application files.
