Azure Virtual Networking

Azure virtual networks (VNets) and subnets enable seamless communication between Azure resources such as VMs, web apps, and databases. They also facilitate interaction with users on the internet and your on-premises client computers. Think of an Azure virtual network as an extension of your on-premises network, integrating and linking various Azure resources.

Key Networking Capabilities

Azure virtual networks offer several essential features, including:

• Isolation and Segmentation : Create isolated virtual networks with specific IP address spaces.
• Internet Communications : Enable resources to communicate with the internet.
• Communication Between Azure Resources : Securely connect different Azure resources.
• Communication with On-Premises Resources : Bridge Azure resources with on-premises environments.
• Routing Network Traffic : Manage and direct network traffic.
• Filtering Network Traffic : Implement security measures to control traffic.
• Connecting Virtual Networks : Link multiple virtual networks for a comprehensive network architecture.

Isolation and Segmentation

Azure virtual networks allow you to establish multiple isolated networks by defining private IP address spaces. These IP ranges are exclusive to the virtual network and are not routable on the internet. You can divide these IP spaces into subnets, each with its own designated address space.

For DNS resolution, Azure provides a built-in service, or you can configure the virtual network to use your own internal or external DNS servers.

Internet Communications

To facilitate incoming connections from the internet, assign a public IP address to your Azure resource or place it behind a public load balancer.

Communication Between Azure Resources

Secure communication between Azure resources is achieved through:

• Virtual Networks : Link VMs with other Azure services such as Azure Kubernetes Service…
