Introduction

virtual machine, abbreviated as VM, is similar to any other physical computer, such as a laptop, smartphone, or server. It features a CPU, RAM, and discs for storing your files and the ability to connect to the internet if necessary. VMs are generally conceived of as virtual or software-defined computers within physical servers.

Virtual machines can be created and managed with the following tools

  1. Azure Portal
     
  2. Azure PowerShell and ARM templates
     
  3. Azure CLI
     
  4. Client SDK's
     
  5. REST APIs

Virtual Machine Working

Virtualization is the process of establishing a software-based or "virtual" version of a computer with a dedicated CPU, memory, and storage that is "borrowed" from a physical host machine (such as your personal computer) and a remote server (such as a server in a cloud provider's datacenter). A virtual machine is a computer file, commonly referred to as an image, that mimics the behavior of a real computer. It can run as a separate computing environment in a window, often to run a different operating system—or even to serve as the user's whole computer experience, as is usual on many people's work computers. Because the virtual machine is partitioned from the rest of the system, the software inside it cannot interfere with the principal operating system on the host computer.

VMs uses

  • We are creating and deploying cloud-based apps.
     
  • I am trying out a new operating system (OS), which may include beta versions.
     
  • We are creating a new environment to run dev-test scenarios easier and faster for developers.
     
  • I am creating a backup of your current operating system.
     
  • Installing an earlier OS allows you to access virus-infected files or use an old application.
     
  • Running software or apps on operating systems for which they were not designed.

Advantages of Virtual Machines

Virtual machines, while they run like different computers with their own operating systems and programs, have the advantage of being fully independent of one another and the physical host machine. A hypervisor, or virtual machine management, is a piece of software that allows you to run several operating systems on many virtual machines at the same time. This will enable you to run Linux virtual machines on a Windows OS, for example, or run an older version of Windows on a more recent Windows OS.

Because virtual machines are self-contained, they are also incredibly portable. A VM on one hypervisor can be moved to another hypervisor on a different machine almost instantly.

Virtual machines offer numerous advantages due to their flexibility and portability, including:

Agility and speed: Spinning up a VM is significantly easier and faster than setting up a completely new environment for your developers. Virtualization speeds up the process of conducting development scenarios.

Cost savings: running numerous virtual environments from a single piece of infrastructure reduces your actual infrastructure footprint dramatically. This improves your bottom line by reducing the number of servers you need to manage and saving money on maintenance and electricity.

Reduced downtime: because VMs are so portable and easy to migrate from one hypervisor to another on a separate system, they're an excellent backup option if the host suddenly drops.

Scalability: VMs make it easier to expand your programs by allowing you to add more real or virtual servers and share the workload across them. As a result, your apps' availability and performance will improve.

Benefits of using a guest operating system on a virtual machine:  Because virtual machines run different operating systems, utilizing a guest operating system on a virtual machine allows you to run apps with questionable security while also protecting your host operating system. VMs also improve security forensics and are frequently used to safely research computer infections by separating them from their host machine.

Steps for creating Azure Virtual machine in Azure Portal

  • Step 1: Go to All Services, then click the Virtual Machine button, as seen in the image below.
     
  • Step 2: Select Create from the drop-down menu, and you'll be sent to the Create Virtual Machine page.
     
  • Step 3: Next, choose "Create VM from Azure marketplace" to select an image for your virtual machine from the Azure marketplace.
     
  • Step 4: After you've chosen an image, the first thing you'll need to do is give your virtual machine a name.
     
  • Step 5: Now, choose the size and type of virtual machine that best suits your needs. Then, create a User name and password for your Virtual Machine, and click Next.
     
  • Step 6: Now that you're on the disc tab, choose the disc type you require and click Next to be taken to the networking page.
     
  • Step 7: For the virtual machine, choose a virtual network, subnet, and IP address. Because we're making it for training purposes, we're leaving it at default.
     
  • Step 8: Finally, go to the Management tab and select the boot and OS diagnostic option. Then click the following button.
     
  • Step 9: You can add an extension to the virtual machine in advanced settings.
     
  • Step 10: Click the create button in the review and make a window.
     
  • Step 11: When you click Create, the next step will begin. Allow a few minutes for the processing to complete.

Frequently Asked Questions

What is Azure Disk Storage, and how does it work? 

Azure Disk Storage is a service that provides high-performance, high-reliability block storage for Azure Virtual Machines. Azure Disk Storage provides the price-performance you need for your mission and business-critical apps, with unparalleled resiliency, seamless scaling, and built-in security.

What sets Azure Virtual Machines apart from other virtual machines?

Both yes and no! Azure Virtual Machines is an Azure infrastructure service (IaaS) that allows you to create persistent VMs that can run almost any VM server workload. They're image service instances offering on-demand scalable computer resources with usage-based charging.

So, Azure Virtual Machines is a service that provides virtual machines (VMs) that are optimized for general-purpose or storage, memory, compute, and graphics-intensive workloads and come in a range of types and sizes to match your demands while staying within your budget.

What is infrastructure as a service (IaaS), and how does it work?

The most basic type of cloud computing service is this. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, and operating systems—from a cloud provider like Microsoft Azure on a pay-as-you-go basis.

What is a hypervisor, and how does it work? 

On the same physical computer, multiple virtual machines can run simultaneously, all managed by a hypervisor. A hypervisor is a piece of software that connects the actual hardware to the virtual "hardware" of a virtual machine. This is quite similar to how an operating system on a typical computer works: the hypervisor ensures that each VM gets the resources it requires from the actual server in a timely and orderly way, much like a school crossing guard helps many pupils safely cross a busy crossroads.

What is the definition of a virtualization machine? Is a virtual machine the same thing?

Virtualization is generating a software-based or "virtual" version of something, whether it's computation, storage, networking, servers, or apps. Virtualization as a technology has a long history, and it is still highly relevant to developing a cloud computing strategy today. Virtualization is the technique, and the computers created with it are generally referred to as virtual machines or simply VMs.
