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.
Queue-it helps in high-demand and limited-supply situations—like sneaker releases, ticket on-sales, or government registrations—that can easily overwhelm a website or app. In these high-demand situations, online visitors are redirected to a customizable waiting room and then throttled back to the website or app. In the case of scheduled sales or registrations, organizations can create a scheduled waiting room that holds early visitors on a countdown page and randomizes them just like a raffle once the sale or registration begins, giving everyone an equal chance. Later visitors are then added to the end of the line on a first-come, first-served basis. Queue-it's virtual waiting room can also guard against traffic overload 24/7, working as a safety net by constantly monitoring traffic inflow and only activating the waiting room when traffic exceeds the configured thresholds. By controlling online traffic, Queue-it's virtual waiting room lets organizations control their online experience. They capture sales, deliver seamless user experiences, ensure fairness, and protect brand reputation.
