Connect, secure, and manage network traffic for your Azure VMs
This documentation provides comprehensive guidance on configuring and managing the networking aspects of Azure Virtual Machines (VMs). Understanding VM networking is crucial for ensuring your applications are accessible, secure, and performant.
Azure Virtual Machines leverage Azure's robust global network infrastructure to provide flexible and scalable networking capabilities. Key components include:
Learn how to create and configure VNets, subnets, and associate NICs with your VMs. This includes understanding IP addressing schemes, address spaces, and subnet delegation.
Learn more about Virtual Networks
Discover how to assign static or dynamic public IP addresses to your VMs for internet connectivity. Understand the use of Azure DNS for name resolution.
NSGs act as a basic firewall for controlling inbound and outbound network traffic to and from Azure resources. Learn how to create rules to allow or deny traffic based on IP address, port, and protocol.
Manage Network Security Groups
Explore Azure Load Balancer and Application Gateway for distributing traffic and ensuring the availability of your applications. Understand concepts like health probes and session affinity.
Understand how NAT is used for inbound and outbound connections to VMs. This includes configuring NAT rules for specific ports.
NAT Gateway and Load Balancer NAT Rules
Connect your on-premises networks to your Azure VNets using Site-to-Site VPNs or Azure ExpressRoute for seamless hybrid cloud solutions.
Connect VNets together using VNet peering. This allows resources in different VNets to communicate with each other as if they were on the same network.
Securely access Azure PaaS services from your VNet using service endpoints or Azure Private Link for private connectivity.
Virtual Network Service Endpoints
Utilize Azure Network Watcher to monitor, diagnose, and gain insights into your Azure network performance and health.
Deploy Azure Firewall as a managed, cloud-based network security service that protects your Azure Virtual Network resources. It's a fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability.
