Azure Virtual Networks, Virtual Machines & Network Security Groups

Introduction: 

Azure Virtual Networks (VNets) are the fundamental building block of your private network in Azure. VNets enable you to build complex virtual networks that are similar to an on-premises network, with additional benefits of Azure infrastructure such as scale, availability, and isolation. A VNet is a representation of your own network in the cloud. It is a logical isolation of the Azure cloud dedicated to your subscription. You can use VNets to provision and manage virtual private networks (VPNs) in Azure and, optionally, link the VNets with other VNets in Azure, or with your on-premises IT infrastructure to create hybrid or cross-premises solutions. Each VNet you create has its own CIDR block and can be linked to other VNets and on-premises networks as long as the CIDR blocks do not overlap. You also have control of DNS server settings for VNets, and segmentation of the VNet into subnets. 

In this Lab exercise, you will: 

• Provision a Virtual Network with default settings  
• Change the IP Address range of the network, while there are no devices (Virtual Machines) connected to the network
• Add a Virtual Machine to the amended network 
• Change the IP Address range of the network with the new connected device present, and move the connected device to a new subnet
• Create a Second Virtual machine 
• Create a Network Security group to allow remote desktop connectivity
• Test Remote and internal connectivity using one of the Virtual Machines
