10. What are the three principal segments of the Windows Azure platform?
Windows Azure has three principal segments: Compute, Storage, and Fabric.
A. Windows Azure Compute
Windows Azure gives a code that can be managed by the hosting environment. It gives the calculation benefit through parts. Windows Azure backs three types of roles:
- Web roles utilized for web application programming and upheld by IIS7
- Worker roles utilized for foundation handling of web roles
- Virtual machine (VM) roles utilized for moving windows server applications to Windows Azure in a simple way
B. Windows Azure Storage
It gives four types of storage services:
- Queues for informing between web parts and worker roles
- Tables for storing structural data
- BLOBs (Binary Large Objects) to store contents, records, or vast information

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.
That’s it for our basic Azure Architect interview questions. Let’s move onto the next section on Intermediate Azure Administrator interview questions.
