What is Azure Virtual Network?
Azure Virtual Network (VNet) is the cloud networking foundation for your organization. It enables you to securely connect Azure resources to each other, to the internet, and to your on-premises environments.
With Azure VNet, you can provision and manage a private network in the cloud. You have full control over IP address spaces, DNS servers, route tables, and network security groups (NSGs) that allow or deny traffic based on source and destination IP addresses, ports, and protocols.
Key Benefits
Isolation and Segmentation
Create logically isolated networks in Azure to group and secure resources, with control over traffic flow between subnets.
Hybrid Connectivity
Seamlessly connect your on-premises networks to Azure VNets using VPN Gateway or ExpressRoute for a true hybrid cloud experience.
Enhanced Security
Implement granular security policies with Network Security Groups (NSGs), Azure Firewall, and DDoS protection to safeguard your assets.
Scalability and High Availability
Design your network to scale with your applications and ensure high availability through features like Availability Zones and load balancing.
Core Components
- Virtual Network (VNet): The fundamental building block for your private cloud network.
- Subnets: Divisions of your VNet's IP address space, allowing for resource grouping and security segmentation.
- Network Security Groups (NSGs): Stateful packet filtering firewalls to control inbound and outbound traffic to network interfaces and subnets.
- IP Addressing: Private and public IP addresses for resources within your VNet.
- Routing: Default system routes, custom route tables, and BGP for directing traffic.
- Gateway Transit: Allow a virtual network to connect to a virtual network gateway in a peered virtual network.
Common Use Cases
- Deploying multi-tier applications with segregated tiers (e.g., web, application, database).
- Extending your on-premises datacenter to Azure.
- Securing sensitive workloads with advanced network security features.
- Creating a centralized network hub for multiple spoke virtual networks.
