Interview Questions for Azure Developer
Table Of Content
Microsoft Azure, formerly known as Windows Azure, is Microsoft’s public cloud computing platform. It provides a broad range of cloud services, including compute, analytics, storage and networking. Users can pick and choose from these services to develop and scale new applications or run existing applications in the public cloud.
The Azure platform aims to help businesses manage challenges and meet their organizational goals. It offers tools that support all industries — including e-commerce, finance and a variety of Fortune 500 companies — and is compatible with open source technologies. This gives users the flexibility to use their preferred tools and technologies. In addition, Azure offers four different forms of cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and serverless functions.
Microsoft charges for Azure on a pay-as-you-go (PAYG) basis, meaning subscribers receive a bill each month that only charges them for the specific resources and services they have used.
Embark on your journey into the world of cloud computing with our curated set of Basic Azure Interview Questions & Answers. Designed for both beginners and experienced professionals, this resource delves into fundamental aspects of Microsoft Azure. Gain insights into key Azure services, deployment models, security considerations, and best practices.
Basic Azure Interview Questions
1. What is Azure Cloud Service ?
Cloud service can convey multiple web applications in Azure, characterizing a number of parts to disseminate handling and permit adaptable scaling of your application. A cloud service comprises a minimum of one web part, as well as specialist parts, each with its own particular application documents and design. The fundamental favorable position of cloud service is the capacity to help more complex multilevel structures.

Table: A table is a collection of entities. Tables don’t uphold a blueprint on elements, which implies that a solitary table can contain substances that have distinctive arrangements of properties. A record can contain numerous tables.
Entity: An entity is an arrangement of properties, like a database row. An entity can be up to 1 MB in size.
Properties: A property is a name-value pair. Every entity can incorporate up to 252 properties to store data. Every entity likewise has three system properties that determine a segment key, a row key, and a timestamp.
14. What is autoscaling in Azure ?
Scaling by including extra instances is frequently referred to as scaling out. Windows Azure likewise supports scaling up by utilizing bigger roles rather than more role instances.
By adding and expelling role instances to our Windows Azure application while it is running, we can adjust the execution of the application against its running costs.
An autoscaling solution reduces the amount of manual work engaged in dynamically scaling an application.
15. What are the features of Windows Azure ?
Windows Azure runs and stores the information on Microsoft data centers.
The main features are as follows:
- Websites enable the designers to assemble the sites utilizing ASP.NET, PHP, etc., and send these websites utilizing FTP, Git, etc.
- SQL database, formally known as Azure database, makes, broadens, and scales the application into the cloud utilizing Microsoft SQL Server.
- This is Microsoft’s Platform as a Service that supports multilevel applications and automated deployment.
16. What are the differences between a public cloud and a private cloud ?
Private clouds are those that are constructed solely for an individual enterprise. They enable a firm to have applications in the cloud while tending to concerns with respect to data security and control that is frequently ailing in a public cloud environment.
Private cloud is otherwise called an internal cloud or enterprise cloud and dwells on the organization’s Intranet or hosted data center where the data is protected.
17. What is IaaS, PaaS, and SaaS ?
IaaS: IaaS is short for Infrastructure as a Service. It offers a range of capabilities, such as OS and network connectivity, that are at the infrastructural level. It follows a pay-per-use policy. It is used to host applications. Azure VM and VNET are examples of this kind of infrastructure.
PaaS: PaaS is an acronym for Platform as a Service. It primarily includes underlying infrastructure abstraction that allows quicker development of applications without the hassle of hosting management. Azure web apps, cloud services, storage services, etc., are all examples of PaaS.
SaaS: SaaS stands for Software as a Service. These applications are delivered with the help of a service delivery model where applications are simply used by an organization. SaaS follows subscription-based payments or ads. Examples of SaaS are Gmail, Office 365, SharePoint Online, etc.

NSG or Network Security Group contains a list of ACL rules that allow or deny network traffic to subnets, network interface cards (NICs) linked to a subnet, or both. When an NSG is connected to a subnet, the ACL rules are for all virtual machines that are located in that subnet. The traffic restrictions to an individual NIC are achieved by linking the NSG directly to that NIC.
21. What is Azure Redis Cache ?
Azure Redis Cache is an in-memory Redis cache system by Azure that helps web applications to optimize performance. Data is fetched from the backend database and stored in the Redis cache for the first request. On subsequent requests, data is fetched from the Redis cache. Azure Redis cache provides powerful and secure caching mechanisms by using Azure Cloud.
22. Define Azure storage key ?
Azure storage key is used to authenticate access to Azure storage service data depending on the project requirements. There are two types of storage keys that are used for authentication:
- Primary access key
- Secondary access key, to avoid downtime of the website or application
CSPack is a command-line tool that generates the service package file and prepares an application for deployment in Azure or Compute Emulator. Every cloud service type project includes the cloud service configuration file, .cscfg file, generated using CSPack. It stores:
- The number of role instances for each role deployment
- The certificate thumbprints
- User-defined configurations
24. What do you understand about cloud computing ?
- Cloud computing refers to the usage of computing resources (servers)on the internet (refers to the term cloud) for the purpose of storing, managing, analyzing, and processing the data. Here, instead of maintaining our own servers, we use the infrastructure provided and maintained by third-party vendors such as Microsoft, AWS, etc, and pay them based on the server usage time duration.
- Cloud computing enhances the speed of execution, ensures flexibility of resources, and easier scalability.
- Cloud computing can be used to attain high fault tolerance and high system availability and this can also be done dynamically as per the infrastructural requirements of the application.
25. What are the various models available for cloud deployment ?
There are 3 models available for cloud deployment:
- Public Cloud: In this model, the cloud infrastructure is owned publicly by the cloud provider and there are chances that the server resources could be shared between multiple applications.
- Private Cloud: Here, the cloud infrastructure is owned exclusively by us or exclusive service is provided by the cloud provider to us.
- This includes hosting our applications on our own on-premise servers or hosting the application on a dedicated server provided by the cloud provider.
- Hybrid Cloud: As the name itself says, this model is the hybrid combination of private cloud and the public cloud.
- This might include the scenario of using on-premise servers for processing confidential, sensitive data and using public cloud features for hosting public-facing applications.
26. How many cloud service roles are provided by Azure ?
Cloud service roles comprise a set of application and configuration files. There are 2 kinds of roles provided by Azure:
- Web role: This provides a dedicated web server belonging to IIS (Internet Information Services) that is used for automatic deployment and hosting of front-end websites.
- Worker role: These roles help the applications hosted within them to run asynchronously for longer durations and are independent of the user interactions and generally do not use IIS. They are also ideal for performing background processes. The applications are run in a standalone manner.
False. Azure does not support this.
