Networking in Azure

Networking in Azure is a critical part of designing and deploying any Azure solution. Networks connect services, applications, and resources securely inside the Azure cloud, out to on-premises networks, and to other networks in Azure. Networking in Azure is based on the following key concepts:

• Virtual Networks (VNETs): These are the foundational building blocks of Azure networking. VNETs provide isolation and security for your Azure resources, much like traditional networks provided by on-premises routers and switches.
• Subnets: These are logical partitions within a VNET that provide further granularity for your Azure resources. Subnets can be used to isolate resources based on functionality, security, or other criteria.
• Network Security Groups (NSGs): These are stateful firewalls that control traffic flow to and from resources in your VNETs.
• Route Tables: These are used to control how traffic is routed within and between VNETs.
• Azure Load Balancers: These are used to distribute traffic across multiple instances of your application or service.
• Azure Virtual Private Network (VPN) Gateways: These are used to create secure connections between your on-premises networks and Azure VNETs.
• Azure ExpressRoute: This is a dedicated, private connection between your on-premises network and Azure.
• Microsoft Azure Firewall: This is a managed, cloud-based firewall service that provides advanced threat protection for your Azure VNETs.
