Virtual Network Overview
Azure Virtual Network (VNet) enables Azure resources to securely communicate with each other, with users on the internet, and with your on-premises on-premises environment. It's a logical isolation of the Azure cloud dedicated to your subscription.
Key Concepts
- Subnets: Divide your VNet into smaller address spaces, allowing for segmentation and better management of resources.
- IP Addressing: Assign private and public IP addresses to your resources for communication.
- Network Security Groups (NSGs): Act as a basic firewall to control inbound and outbound traffic to network interfaces, VMs, and subnets.
- Route Tables: Define custom routes to control traffic flow within your VNet and to other networks.
- Peering: Connect two VNets together to enable resources in each VNet to communicate with each other.
- VPN Gateway: Securely extend your on-premises networks to Azure via encrypted tunnels.
- ExpressRoute: Provide private, high-bandwidth, low-latency connections between your on-premises environment and Azure.
