Recommended for Advanced Skills: Use Nginx to reduce IIS load and provide a smooth network

Since the website updated AAF, the load on the www site Server (IIS) has been continuously increasing, from the average 30% to 70%; the CPU has maintained such a high load, there will be problems; then we started to try to use Nginx to hold the IIS server in front to reduce the load on the IIS server. Nginx is used as the response proxy. In this architecture, Nginx is placed in a VIPPool below F5.

Nginx is used as the response proxy, ArchitectureIn this case, Nginx is placed in a VIP Pool below F5, and Nginx returns the Proxy from IISPoo. The configuration file is as follows:
