Azure compute resources called virtual machine scale sets can be used to deploy and manage a collection of identical VMs. Scale sets are made to provide real autoscale with uniform VM configurations, so pre-provisioning VMs is unnecessary. Large-scale services aimed at big computing, big data, and containerized workloads are so simpler to develop.

14. Are data disks supported within scale sets?

Yes. Every VM in a scale set can have a defined associated data disc configuration. Other possibilities for data storage include:

• Cloud files (SMB shared drives)
• Temp drive (local, not backed by Azure Storage)
• OS drive 
• Data service Azure (for example, Azure tables, Azure blobs)
• An outside data service (for example, a remote database)

15. What are Availability Sets?

A logical collection of VMs called an availability set gives Azure insight into how your application is designed to offer redundancy and availability. To support a highly available application and adhere to the 99.95% Azure SLA, it is advised that two or more VMs be established within an availability set. For unplanned maintenance events when a single VM is used with Azure Premium Storage, the Azure SLA is in effect. 

16. What is a Fault Domain?

A fault domain is a logical collection of the underlying hardware that, like a rack in an on-premise data centre, shares a single power source and network switch. The Azure platform automatically distributes our VMs among various fault domains as we construct them inside an availability set. This strategy reduces the effects of potential hardware malfunctions, network failures, or power outages. 

17. What is an Update Domain?

An update domain is a logical collection of the underlying hardware that can reboot or go through maintenance simultaneously. The Azure platform automatically distributes your virtual machines among these update domains when you construct them within an availability set. With this strategy, you can be sure that while the Azure platform is undergoing routine maintenance, at least one instance of your application will always be active. During planned maintenance, the restart order of the update domains may not be sequential, but only one update domain is rebooted at once. 

18. Do Azure availability sets work with scale sets?

Yes. An implicit availability set with five fault domains and five update domains is known as a scale set. More than 100 VMs in a scale set will typically span numerous placement groups, which are analogous to multiple availability sets. The same virtual network may house both a scale set and an availability set of virtual machines. The placement of control node VMs, which frequently require special configuration, in an availability set and data nodes in the scale set is typical. 

19. What are break-fix issues?

An industry phrase for technical issues is "break-fix issue," which refers to the effort needed to support a technology when it usually malfunctions and needs assistance from a support group to get back in working order.

The management of services in the Azure portal is permitted for this role. You can add people as co-admins if they need to log in and use the same subscription to access services.
• In order to administer the directory- and identity-related functionalities, Azure AD offers a diverse set of admin roles. The Azure portal or the Azure classic portal's numerous capabilities will be accessible to these administrators. What an admin can do, such as create or update users, delegate administrative rights to others, reset user passwords, manage user licences, or administer domains, depends on their job.

31. What are the limitations for customers for using managed disks?

The restrictions connected to storage accounts are eliminated by Managed Disks. However, there is a default cap of 2000 managed discs per subscription.

32. What is the difference between Storage Queues and Service Bus Queues?

• The Azure Storage Queue is easy to use, and developers report positive results. The Azure Storage Emulator is used locally, and debugging is simple. We can quickly view the top 32 messages in Azure Storage Queues thanks to the tooling, and if the messages are in XML or JSON, we can view their contents right from Visual Studio. Additionally, these queues can be cleaned of their contents, which is particularly helpful for QA and development tasks.
• The Azure Service Bus Queues are sophisticated and supported by numerous practical methods, making them enterprise-worthy. They can forward messages to other Queues and Topics because they are a part of the Service Bus. Because they include a built-in dead-letter queue and a time limit that we set, mails are not immediately deleted after seven days.
• Additionally, Azure Service Bus Queues have the option to automatically delete themselves after a defined period of inactivity. When we build Queues for each user, this function is incredibly useful because it automatically cleans up Queues for users who haven't engaged with them in the last month. It's also a fantastic strategy to reduce expenditures. Paying for storage that we don't need shouldn't be necessary. The maximum size of these queues is 80 GB. Once we've hit this cap, exceptions will start coming into our application.

33. What is the Redis database?

Just a logical division of data within the same Redis instance constitutes a Redis database. All databases use the shared cache memory, and the amount of memory actually used by a particular database depends on the keys and values that are kept there. A C6 cache, for instance, contains 53 GB of memory. We have the option of distributing the 53 GB across different databases or putting it all in one database. 

34. Can we add an existing VM to any availability set?

No. We must build the VM inside the set if we want it to be a part of the availability set. After a VM is constructed, there is currently no way to add it to an availability set. 

35. How much storage can we use with a virtual machine?

Up to 1 TB can fit on each data disc. Depending on the size of the virtual machine, you can use a certain number of data discs.
