(Recommended tutorial: nginx usage tutorial)
1. Protect service security
Hide the IP of the service node;
Place the service node behind the firewall to avoid direct attacks on the business node server.
2. The service node is more focused on business while improving performance
Due to the existence of a reverse proxy, the reverse proxy server can be To implement functions that have nothing to do with the business, such as https and gzip compression;
provides dynamic and static separation and sends static files to static servers or local file systems to avoid business nodes processing these and business Irrelevant requests;
Provides a caching mechanism to cache some dynamic content that will not change in a short period of time at the reverse proxy server layer to reduce the request volume of the business server;
Since the control lies with the proxy service, requests can be dynamically allocated based on the performance of the service node to achieve the best performance of the service node.
It is precisely because Ngxin has introduced the reverse proxy feature that both requests and responses must go through Nginx, thus bringing a lot of possibilities to Nginx. Such as load balancing, HTTP caching, etc.
