Cloud Networking Services

This section provides comprehensive documentation on Microsoft's cloud networking services, empowering you to design, deploy, and manage robust, scalable, and secure network infrastructures in the cloud.

Core Networking Concepts

Understand the fundamental building blocks of cloud networking:

• Virtual Networks (VNet): Isolate your cloud resources with private, secure networks. Learn about address spaces, subnets, and routing.
• Load Balancing: Distribute incoming traffic across multiple resources to improve availability and performance.
• DNS: Resolve domain names to IP addresses with our robust cloud DNS services.
• VPN Gateway: Securely connect your on-premises networks to your cloud virtual networks.
• ExpressRoute: Establish private, dedicated connections between your on-premises infrastructure and Microsoft Azure.

Key Networking Services

Azure Virtual Network (VNet)

Azure Virtual Network is the fundamental building block for your private network in Azure. It enables you to create isolated network environments for your Azure resources.

• Creating and Managing VNets
• Subnetting Strategies
• IP Addressing in VNets

Azure Load Balancer

Azure Load Balancer is a Layer 4 load balancer that distributes incoming traffic over a pool of backend resources. It is highly available and scalable.

• Standard Load Balancer vs. Basic Load Balancer
• Configuring Health Probes
• Load Balancing Rules

Azure DNS

Azure DNS provides a reliable and high-performance domain name resolution service that uses Microsoft Azure infrastructure.

• Hosting DNS Zones
• Managing DNS Records
• Alias Records

Azure VPN Gateway

Azure VPN Gateway provides secure, cross-premises connectivity through encrypted tunnels.

• Site-to-Site VPNs
• Point-to-Site VPNs
• Network Security Groups (NSGs)

Azure ExpressRoute

Azure ExpressRoute allows you to create private connections to Microsoft Azure and Microsoft 365. ExpressRoute connections do not go over the public Internet.

• ExpressRoute Connectivity Providers
• Configuring Routing
• ExpressRoute Global Reach

Network Security

Securing your cloud network is paramount. Explore our security features:

• Network Security Groups (NSGs): Filter network traffic to and from Azure resources in an Azure virtual network.
• Azure Firewall: A managed, cloud-native network security service that protects your VNet resources.
• Azure DDoS Protection: Provides enhanced DDoS mitigation capabilities.
• Web Application Firewall (WAF): Protects your web applications from common web exploits.

Network Monitoring and Diagnostics

Gain insights into your network's performance and health:

• Azure Network Watcher: Provides tools to monitor, diagnose, and view metrics for your Azure network resources.
• Traffic Analytics: Analyze your network traffic logs to identify security threats and optimize performance.
• Connection Troubleshooter: Diagnose connectivity issues between Azure resources.
