Azure networking provides a comprehensive set of cloud networking capabilities that you can use to build and manage your business solutions. Azure networking services help you connect Azure resources to each other, connect Azure resources to the internet, and connect on-premises networks to Azure.
Key Networking Concepts
Understanding the fundamental building blocks of Azure networking is crucial for designing secure, scalable, and highly available cloud solutions. Here are some core concepts:
- Virtual Network (VNet): A virtual network is the fundamental building block for your private network in Azure. It represents your own private network in the cloud. You can use VNets to provision and manage Azure resources privately and securely.
- Subnets: VNets are divided into subnets to logically group resources and manage IP address spaces. This allows for better organization and security segmentation.
- Network Security Groups (NSGs): NSGs act as a distributed firewall to protect your virtual network resources. They allow or deny network traffic to Azure resources connected to an Azure Virtual Network.
- Public IP Addresses: Resources that need to be accessible from the internet or communicate with the internet require a Public IP address.
- Load Balancers: Distribute incoming network traffic across multiple backend resources to improve application availability and responsiveness.
- Application Gateway: A web traffic load balancer that enables you to manage traffic to your web applications. It supports SSL termination, cookie-based session affinity, and round-robin distribution.
- VPN Gateway: Connects your on-premises networks or other Azure VNets to Azure VNets securely over the public internet using a VPN tunnel.
Benefits of Azure Networking
- Scalability: Easily scale your network resources up or down based on demand.
- Security: Implement robust security measures with features like NSGs, Azure Firewall, and DDoS protection.
- High Availability: Design resilient applications with load balancing and traffic management services.
- Global Reach: Deploy your applications and services across multiple Azure regions worldwide.
- Hybrid Connectivity: Seamlessly connect your on-premises infrastructure with Azure resources.
