Question

I hope the explanation is easier to understand. Thank you. By the way, please explain what reverse proxy is.

Answer 1

The answer comes from the amazing Google

• PM2 is a very easy-to-use Node.js service startup container. It allows you to keep your applications running forever, with no downtime required to reload them.

• nginx is a lightweight web server. Compared with Apache, it has the advantages of less memory and high concurrency. Using the epoll model, nginx is very efficient. And can be hot upgraded.

• A forward proxy is a server located between the client and the origin server. In order to obtain content from the origin server, the client sends a request to the proxy and specifies the target (origin server), and then the proxy forwards it to the origin server. Request and return the obtained content to the client.

• Reverse proxy In computer networks, a reverse proxy is a type of proxy server. It obtains resources from the back-end server based on the client's request, and then returns these resources to the client. Unlike a forward proxy, which acts as a medium to return resources obtained from the Internet to the associated client, a reverse proxy is used as a proxy on the server side, not the client.
