Introduction to Azure Networking
Azure networking provides a comprehensive set of services to connect Azure resources, connect Azure to on-premises environments, and expose Azure hosted applications to the internet.
Leveraging Azure networking services allows you to create scalable, highly available, and secure cloud networks that mirror your on-premises environments or enable entirely new application architectures.
Virtual Networks (VNet)
Azure Virtual Network (VNet) is the foundational building block for your private network in Azure. VNets enable you to provision, and manage Azure resources like Virtual Machines (VMs) with enhanced security and isolation.
Subnets
Divide your VNet into smaller network segments for better organization and security control.
Learn more →IP Addressing
Understand public, private, and dynamic IP address assignments for Azure resources.
Learn more →Network Peering
Connect VNets securely and privately for seamless resource communication across regions.
Learn more →Load Balancing
Distribute incoming traffic across multiple instances of an application or service to improve availability, scalability, and performance.
Azure Load Balancer
Distribute traffic at Layer 4 (TCP/UDP) for high availability and low latency.
Learn more →Azure Application Gateway
A web traffic load balancer that enables you to manage traffic to your web applications at Layer 7 (HTTP/HTTPS).
Learn more →Azure Traffic Manager
A DNS-based traffic load balancer that allows you to distribute traffic optimally to services in different regions.
Learn more →Network Security
Implement robust security measures to protect your Azure resources and applications from network threats.
Network Security Groups (NSGs)
Filter network traffic to and from Azure resources in an Azure virtual network.
Learn more →Azure Firewall
A managed, cloud-based network security service that protects your Azure Virtual Network resources.
Learn more →Azure DDoS Protection
Defend your Azure resources from Distributed Denial of Service (DDoS) attacks.
Learn more →Connectivity Options
Connect your on-premises network to Azure securely and reliably.
VPN Gateway
Establish secure, cross-premises connections between your on-premises network and Azure.
Learn more →ExpressRoute
Create private connections between Azure datacenters and infrastructure that’s on your premises or in a colocation facility.
Learn more →Monitoring & Diagnostics
Gain insights into network performance, traffic flow, and security events.
Azure Network Watcher
Monitor, diagnose, and view metrics for your Azure network resources.
Learn more →NSG Flow Logs
Analyze network traffic flowing to and from network interfaces (NICs) in Azure.
