Microsoft Azure Virtual Machine

What Is a Virtual Machine?

It is a computer file known as an image that functions much like a real computer. One of the folders that contain everything is that one. Windows, Linux, and other operating systems can all run it. As a result, you have the flexibility to run several machines on a single physical computer. In addition, different operating systems are possible for various systems.

The virtual hardware that each of these virtual machines offers includes CPUs, RAM, hard drives, network connections, and other similar components.

What Is Azure Virtual Machine?

Making your own instances is one of the services offered by Azure.

It has a variety of applications:

• Development and test
• Applications in the Cloud
• Extended Datacenter

It is important to keep in mind that you must pay for computation time when using Azure on a per-minute basis.

Their size, operating system, and any installed licensed applications all factor into the price of this.

It is recommended that you set its state to Stopped when not in use to prevent corresponding charges (Deallocated).

With Microsoft Azure, you may receive general-purpose, general-purpose, compute-optimized, memory-optimized, and burstable virtual machines. This service is much more appealing to companies because of the per-second charge. These are some uses for Azure Virtual Machines:

Development and Test

Creating machines with the fundamental and specialized configurations needed to code and test the applications is quick and simple.

Applications in the Cloud

When necessary, one can purchase more virtual machines and turn them off when not needed.

Extended Datacenter

The network of the company can be quickly connected to VMs in the Azure Virtual Network.

Workloads for an Azure Virtual Machine

There are two ways you can go about moving to an Azure virtual machine. You will discover these two crucial approaches to transitioning to an Azure VM in this tutorial on building Azure Virtual Machines.

1. Suitable workloads
2. Unsuitable workloads

Suitable Workloads

It is nothing, but highly available service workloads, such as internet shops for sale.

It may also be used for recurring tasks like:

• Marketing campaigns that are seasonal on a website of an organization.
• Annual Sales during festive holidays.

For unpredictable workloads, such as those at startups where they are oblivious to their expansion.

Organizations that merely want to offload their infrastructure to the cloud can also use it.

Unsuitable Workloads

It is not appropriate for you to shift your applications to the cloud if you cannot notice a cost difference.

There are various laws or ordinances from the authorities or the local government that forbid moving to the cloud because of their laws. 

How to Create an Azure Virtual Machine?

To create an Azure virtual machine, use one of the following methods:

When building an Azure VM, it all depends on the environment you are working in:

Azure Portal

A virtual machine is created through the Azure Portal. Windows is used as the portal.

Templates

A Windows virtual machine can be established with the Resource Manager template. 

Client Disks

Azure Resources can be deployed using C#.

REST API's

Create a virtual machine or update one.

A Virtual Network: What Is It?

This Azure virtual network tutorial will assist you in thoroughly understanding Azure. Customers can construct and administer virtual private networks in Azure thanks to virtual networks. Virtual networks' primary function is to allow instances to communicate with one another. It is possible to link various virtual networks together. You can connect to your on-premises networks using the Azure virtual network. As a result, Azure serves as a virtual extension of your on-site data center. ICMP and UDP are supported by Azure Virtual Networks.

Isolation

When building a virtual network, you can separate each of these networks so that they each function independently.

The virtual network can be set up to use your personal DNA servers.

Internet Communication

By default, any instances you start in an Azure virtual machine can connect to the Internet. As required, you can enable inbound access to resources.

Azure Resource Communication

Regardless of whether the resources are from the same subnet or separate subnets, they can communicate with each other using private IP addresses if they are part of the Azure virtual network.

They offer pre-configured routing between subnets so that users of on-premises networks OS don't have to manage and configure routes.

Virtual Network Connectivity

Resources from any virtual network can communicate with resources from any other virtual network thanks to its connectivity.

On-Premises Connectivity

It is possible to connect a virtual network to an on-premises network so that resources can communicate with each other. 

 Traffic Filtering

By source, IP address, and port, network traffic from resources in a virtual network can be filtered.

Routing

By default, Azure's routing can be overridden with your own routes or by propagating BGP routes over the network gateway.

DHCP in Azure Virtual Network (Dynamic Host Configuration)

Ip addresses are assigned by Azure using Dynamic Host Configuration Protocol services from the ranges you specify for the virtual network. The length of each IP address lease is limitless. You will have a thorough understanding of dynamic host configuration in the Azure Virtual Network after completing this building Azure VM lesson.

You can configure a static private IP address from the range of Ipv4 addresses connected to the virtual network to prevent IP address changes regardless of the condition of the Azure virtual machine.

Microsoft Azure Virtual Network: Subnet

There are one or more subnets in the Azure virtual network.

Subnets break your virtual network into smaller IP ranges to allow logical separation of the resources arranged within each subnet.

A portion of the virtual network space is represented by the IP address range that each subnet contains.

Routing in the Azure Virtual Network

It is nothing more than the default routing of your traffic.

Each subnet in the Azure virtual network had a routing table automatically constructed for it, and system default routes were also included. A few system routes can be replaced with custom routes, and you can also add more custom routes to the route database.

Groups for Network Security

The only thing limiting network traffic at the level of virtual machines is the firewall. Based on the source or destination IP addresses, ports, and protocols, it provides a list of security rules that permit or prohibit inbound or outbound network communication.

Security rules are applied to all resources in the subnet if they are applied to the subnet.
