In this Post you will be Learning and get Understanding Azure Virtual Network, Subnets & Routes.

Azure Virtual Network

• The Azure Virtual Network is a logical representation of a private network in the cloud where we can deploy different kinds of Azure resources like Azure virtual machine, App service environment, Public IP Addresses etc.
• By creating an Azure Virtual Network, we can define our private IP address range on Azure
• The scope of a virtual network is a single region; however, several virtual networks of different regions or same region can be connected together by virtual network peering

Capabilities –

Isolation and segmentation: Resources may be placed in different networks & Subnets to keep them separate from other resources.

Communication with the Internet: All resources in a virtual network can communicate outbound to the Internet by default. By using right routes & Public IP Address we can make possible Inbound communication too.

Communication between resources: Communication between the number of resources inside the virtual network or with other resources through service endpoints.

Communication with on-premises resources: By establishing either point to site VPN or site to site VPN or Express route, your workloads within Azure virtual network can seamlessly communicate with workloads within our on-premises data center.

Filter network traffic: We can use Network Security Groups, Application Security Group, Azure firewall, or third-party network virtual appliance to filter incoming/Outgoing Traffic to and from the resources in the virtual network.

Route network traffic: By default, Azure routes traffic between subnets, connected virtual networks, local networks, and the Internet, we can configure user-defined routes to route all the outbound traffic through a non-default path.

Monitor network traffic: By network security groups and traffic analytics monitoring solution, you’ll be able to carry out extensive monitoring on both inbound and outbound communications.
