Azure Application Gateway
By Microsoft
4.4/5
(158)
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. This capability provides more control over how traffic is distributed to your applications, enhancing both performance and security. Key Features and Functionality: - Layer 7 Load Balancing: Routes traffic based on HTTP request attributes, enabling more precise control over traffic distribution. - Web Application Firewall (WAF): Protects applications from common web vulnerabilities like SQL injection and cross-site scripting by monitoring and filtering HTTP requests. - SSL/TLS Termination: Offloads SSL/TLS processing to the gateway, reducing the encryption and decryption overhead on backend servers. - Autoscaling: Automatically adjusts the number of gateway instances based on traffic load, ensuring optimal performance and cost efficiency. - Zone Redundancy: Distributes instances across multiple availability zones, enhancing resilience and availability. - URL Path-Based Routing: Directs requests to backend pools based on URL paths, allowing for efficient resource utilization. - Host Header-Based Routing: Routes traffic to different backend pools based on the host header, facilitating multi-site hosting. - Integration with Azure Services: Seamlessly integrates with Azure Traffic Manager for global load balancing and Azure Monitor for centralized monitoring and alerting. 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. This comprehensive set of features addresses the needs of organizations seeking to build secure, scalable, and efficient web front ends in Azure.
