Azure Interview Questions: What You Should Know

What are the most important Azure interview questions? If you’re looking to land an interview with one of the cloud computing service’s biggest players, you need to be prepared with the right answers before sitting down at the table. After all, any company that has Microsoft as a major competitor has to make sure that its employees are up-to-date on everything relevant to the job they’re applying for! Here are some of the most important Azure interview questions you should know how to answer. Let’s get started .

Questions on Azure

Cloud computing is not a new concept but still, it is evolving and we are having various terms under cloud computing such as Azure (Microsoft), S3 (Amazon Web Services), OpenStack (Flock Program) to name a few. Cloud computing is being used by organizations across industries for a variety of use cases such as deploying web applications and websites, building scalable software products and games using PaaS tools like App Service, or storing large amounts of data using IaaS services like Windows Azure Storage.

These days even startups and enterprises are thinking about going cloud first to leverage all benefits that come with cloud deployments. Now let us look at some useful Azure interview questions that will help you during your interviews with Microsoft or any other company working in the cloud technology space.

Azure Pricing

The model that most cloud providers use is called pay-as-you-go. Users pay only for resources they actually use, making cloud computing a very cost effective option when compared to on-premises data centers and other traditional deployment options. The exact model used by a provider will be dependent on its platform and services. AWS, for example, uses a different pricing model from Azure. Azure’s service plans are based on usage of compute, storage, and network resources. Azure offers users several ways to purchase these resources: pay as you go (PAYG), reserved instances (RI), or subscription-based consumption (SC).

 Each plan has its own benefits depending on your business needs. For instance, RI enables users to get predictable monthly costs while SC offers more flexibility in terms of usage but may have higher costs overall. Regardless of which plan you choose, Azure’s flexible payment options make it easy for businesses of all sizes to get started with cloud computing without breaking their budgets.

Popular Azure Services

Before diving into Azure interview questions, you should have a strong understanding of some of its popular services. One common way for recruiters to find a great fit for an open position is to ask general Azure cloud service questions. Make sure you can discuss these topics in detail and even cite an example or two from your experience. Let’s look at some examples now .

 Microsoft Azure offers three main services: Compute, Web Apps, and Storage. When it comes to compute services, Azure provides both Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). IaaS allows users to set up virtual machines on demand with different operating systems such as Windows Server 2012 R2 and Linux distributions such as Ubuntu 12.04 LTS or CentOS 6.

Types of Cloud Deployment Models

When you deploy an application on Azure, you have three different models to choose from. Each model is a little different and is appropriate for a specific kind of application. The three models are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). PaaS provides everything that you need to run your code, including compute resources, storage and databases.

 With IaaS, you are responsible for providing all of those things yourself. SaaS is primarily used for applications that focus on delivering software or services to consumers over an Internet connection but can also be used in other scenarios. Applications such as Salesforce use SaaS.

 Azure offers a wide range of SaaS solutions and these include Microsoft Office 365, Dynamics CRM Online and Windows Intune. Some Azure features are available only through specific cloud models.

 For example, SQL Database is available only through PaaS; Virtual Machines (VMs) run only with IaaS; and Web Sites run with both PaaS and IaaS. When you’re ready to deploy your application on Azure, it’s important to understand which model will work best for your needs.

How is Azure Better than AWS?

Though AWS and Azure are often discussed in tandem, it’s important to note that they do have some significant differences. Azure, for example, is well-known for being more flexible than AWS when it comes to deployment models. Both offer public cloud services (which are offered over internet connections) and on-premises deployments (which can use custom software running in a private data center).

AWS offers almost no on-premises options; Azure has both public and private options. Microsoft has essentially built their own hybrid cloud and they work very hard to make sure you know that there’s no need to make a decision between public or private today.

Use Cases

These are external scenarios that show how an Azure customer could use Microsoft’s cloud offerings. Possible use cases include a company looking to move its systems and applications to Azure, a developer seeking access to Microsoft’s latest services, or companies that want to reduce operational costs. Answers should speak directly to those potential customers.

The first use case is pretty straightforward: why might someone want to move their on-premises systems and applications to Azure? Be specific, but also make sure you touch on risk factors and roadblocks that could stand in your way. Focus on cost savings when explaining what it would take for companies who already have a robust IT department with established standards for data storage or application testing.
