1. What kind of services are offered in the cloud?
This question is one of the most frequently asked Azure interview 
questions. You can start your answer by saying what the services 
are and how they are different from each other. The service 
models for cloud computing are:
• Infrastructure as a Service (IaaS): This paid service provides users 
with high-level APIs. It is an instant computing infrastructure that is 
managed and provisioned over the internet. Examples of IaaS are 
Azure VM and Amazon EC2.
• Platform as a Service (PaaS): This service allows multiple                       
developers to work on a single project without having to worry 
about the management of the hosting infrastructure. Examples of 
PaaS are Azure SQL and Azure Storage.
• Software as a Service (SaaS): This service includes applications 
used by organizations that they usually pay for. For example, Ofice 
360.
2. What is the difference between Web role and 
Worker role?
For this Azure interview questions, you have to talk about what web 
role and worker role are and how they are different from each 
other. Basically, a web role can use languages that are supported 
by the IIS platform to deploy a website. This role is customized and 
configured for running web applications. Unlike Web Role, which is 
used to deploy a website, Worker Role carries out the background 
processes and is as helpful to the Web Role.

3. What are the advantages of using a deployment 
environment?

• You can specify which users and pipelines are allowed to target the 
environment.
4. What are the different ways to host web sites in 
Azure?
This is one of the most asked Azure interview questions. Azure supports 
App Service (PaaS), Virtual Machine (IaaS), and Service Fabric to host 
websites. App Service is a cost-effective option that allows quick                    
deployment, scalability, and management. If your existing Web Sites 
require Custom Configurations, you can go for Virtual Machine. If you are 
writing a Microservice application that requires stateful services and 
massive scaling, service fabric would be a preferable option.
5. What is a service configuration file?
The cloud service configuration file or .cscfg provides settings of 
configuration for the cloud service as well as individual roles, which 
also include the number of role instances.

The representation of one’s own network in the cloud is known as VNet. 
The instances that you launch in the cloud are isolated from the rest of 
the resources with the help of VNet.
