Azure Virtual Network
Create your own private network infrastructure in the cloud.
OVERVIEW
Create, connect, and manage your virtual networks in the cloud
Find services and resources to seamlessly support your virtual networking and security goals.
- Azure Virtual Network lets you build an isolated, secure environment to run virtual machines (VMs) and applications. You can optionally connect to on‑premises datacenters for a hybrid infrastructure that you control. Bring your own IP addresses and DNS servers, and secure connections using an IPsec VPN or ExpressRoute.
- Virtual Network peering lets you seamlessly connect virtual networks and send traffic over the Microsoft network without using the public internet, gateways, or encryption. You can enforce privacy for global resources and include on‑premises networks through Azure high‑speed networking.
- Azure NAT Gateway routes VM traffic to the internet while keeping VMs and compute resources private. It automatically scales the IP addresses needed for outbound connectivity and minimizes bandwidth impact through software‑defined networking.
- Azure Virtual Network Manager lets you create and manage virtual networks across regions and subscriptions from a single pane of glass. You can segment virtual networks to define management scope, build hub‑and‑spoke or mesh networks, and enforce security requirements consistently.
- Azure Route Server enables network virtual appliances to dynamically exchange route information with virtual networks. It works with existing or new deployments and removes the need to manually configure routes for NVAs, Azure ExpressRoute, and VPN gateways.
- Azure Virtual Network CNI dynamically assigns IP addresses to containers and Kubernetes Pods running in a VM. Pods can connect to a virtual network and its resources, other containers, and peered virtual networks, and access services protected by virtual network service endpoints.
Features
Build secure, scalable virtual networks
Protect data in transit
Add encryption to the Virtual Network default security controls to enhance protection for your data in transit. Learn about Azure Virtual Network encryption.
Enhance security and isolation
Run virtual machines and applications in an isolated and highly secure manner while using private IP addresses. Define subnets and policies to control access.
Rely on the global reach of Azure
Microsoft owns and operates one of the world's largest networks. By default, traffic between Azure resources stays within the Microsoft global network for optimal performance and high reliability. Improve security and reduce latency by avoiding the public internet to pass requests between virtual machines, virtual networks, databases, and other resources.
Build sophisticated network topologies
Create advanced overlay architectures on top of Azure resources and services. Run WAN optimizers, load balancers, and application firewalls in a virtual network and define traffic flows with a high degree of control.
Extend your datacenter to the cloud
Extend your on-premises IT environment to the cloud. Securely connect to a virtual network with an IPsec VPN or a private connection by using Azure ExpressRoute. Authenticate customers for secure access to an on-premises Microsoft Entra ID (formerly Azure Active Directory) service.
Gain flexibility for building apps
Use virtual networks to combine platform as a service (PaaS) and infrastructure as a service (IaaS) resources to reduce network complexity when building or running apps.
Manage virtual networks at scale
Reduce operational overhead by centrally managing your virtual network resources. Create and manage network security rules globally across subscriptions and regions. Manage the configurations for your entire environment from one place. Simplify deployment of configurations to test in specific regions.
