Azure Application Gateway vs HAProxy

Developers should use Azure Application Gateway when building scalable web applications on Azure that require advanced traffic management, such as microservices architectures or multi-tenant applications meets developers should learn haproxy when building scalable web applications that require high availability and efficient traffic management, such as in microservices architectures or high-traffic websites. Here's our take.

Azure Application Gateway

Nice Pick

Developers should use Azure Application Gateway when building scalable web applications on Azure that require advanced traffic management, such as microservices architectures or multi-tenant applications

Pros

• It is ideal for scenarios needing SSL offloading to reduce backend server load, A/B testing with path-based routing, or protecting applications with integrated Web Application Firewall (WAF) capabilities
• Related to: azure-load-balancer, azure-web-application-firewall

Cons

• Specific tradeoffs depend on your use case

HAProxy

Developers should learn HAProxy when building scalable web applications that require high availability and efficient traffic management, such as in microservices architectures or high-traffic websites

Pros

• It is particularly useful for load balancing HTTP/HTTPS traffic, handling failover scenarios, and implementing reverse proxy functionality to offload tasks like SSL encryption from application servers
• Related to: load-balancing, reverse-proxy

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Azure Application Gateway is a platform while HAProxy is a tool. We picked Azure Application Gateway based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Azure Application Gateway wins

Based on overall popularity. Azure Application Gateway is more widely used, but HAProxy excels in its own space.
