Azure Load Balancer Architecture

Understanding the Diagram

This diagram illustrates the core components and traffic flow of an Azure Load Balancer. It depicts how incoming network traffic is distributed across a pool of backend resources, ensuring high availability and responsiveness for your applications.

Key elements typically include:

• Frontend IP Configuration: The public or internal IP address that clients connect to.
• Load Balancing Rules: Define how traffic is mapped from the frontend to the backend pool.
• Backend Pool: A collection of virtual machines or services that will receive the distributed traffic.
• Health Probes: Regularly check the health of backend instances to ensure traffic is only sent to healthy resources.
• Network Security Groups (NSGs): Applied to subnets or network interfaces to filter traffic.
• Virtual Network (VNet): The foundation of your private network in Azure.

The diagram showcases the seamless integration of Azure Load Balancer within the broader Azure ecosystem, providing a robust solution for managing network traffic at scale.
