🚀 Azure Application Gateway: Smart Load Balancing & Security
Ensuring high availability and efficient load balancing is crucial for web applications. Azure offers several traffic management solutions, including Application Gateway, Front Door, Load Balancer, a...
Application Gateway is a great fit when the application needs layer-7 routing, TLS handling, and WAF controls close to the workload.
The design details I would highlight are: use health probes that represent real app readiness, separate listeners/rules clearly, enable WAF in prevention mode only after tuning, and send access/WAF logs to Log Analytics. Those logs are very useful for seeing blocked requests, backend health, latency, and routing issues.
I would also compare it with Front Door early in the design. Application Gateway is regional and VNet-integrated; Front Door is global edge. Many architectures use one or the other, and some use both for different layers.
