By Microsoft

4.4/5

(160)

Product Description

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Unlike traditional load balancers that operate at the transport layer (Layer 4), Application Gateway operates at the application layer (Layer 7), allowing it to make routing decisions based on attributes such as URL paths and host headers.

Primary Value and User Solutions: Azure Application Gateway provides a scalable and highly available solution for managing web application traffic. By operating at the application layer, it offers intelligent routing capabilities that enhance application performance and reliability. The integrated Web Application Firewall ensures robust security against common web threats, while features like SSL/TLS termination and autoscaling optimize resource utilization and reduce operational overhead.
