Azure Virtual Network

What is Azure Virtual Network?

Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. It enables Azure resources, such as Virtual Machines, to securely communicate with each other, with the internet, and with your on-premises networks. VNet offers cloud-native networking capabilities that are highly available and isolated, providing you with control over your IP address space, DNS settings, security policies, and routing.

Key Features

• Resource Isolation: Create private, isolated network environments for your Azure resources.
• IP Addressing: Define your own private IP address space, ensuring control and avoiding conflicts.
• Subnets: Segment your VNet into smaller, manageable subnets for better organization and security.
• Network Security Groups (NSGs): Filter network traffic to and from Azure resources in an Azure virtual network.
• User-Defined Routes (UDRs): Control traffic flow by defining custom routes.
• VPN Gateway: Securely connect your on-premises networks to Azure.
• ExpressRoute: Establish private connections between your premises and Azure.
• Private Link: Access Azure PaaS services over a private endpoint within your VNet.
• Service Endpoints: Securely connect your VNet to Azure services using their PaaS service IP address.

Benefits of Using Azure VNet

• Enhanced Security: Isolate your resources and control traffic flow with powerful security features.
• Scalability: Easily scale your network as your Azure deployment grows.
• Hybrid Connectivity: Seamlessly integrate your cloud and on-premises environments.
• Global Reach: Deploy VNets across multiple Azure regions for global presence.
• Cost-Effectiveness: Leverage cloud-native networking that reduces infrastructure management overhead.
• Compliance: Meet stringent compliance requirements with robust network controls.

Common Use Cases

Azure Virtual Network is essential for a wide range of scenarios, including:

• Deploying multi-tier applications securely.
• Connecting your on-premises data center to Azure.
• Creating a disaster recovery site in Azure.
• Implementing microservices architectures.
• Securing access to Azure PaaS services.
