Phone Book

In this project, we have used 4 servers Nginx, Rest Api, Gateway and Mysql.

You make your request through your laptop to address Nginx server at port 18080 . So Nginx reverse proxy your request to the Rest server. We do this to keep our REST server in front of you hide :)

(Proxy -> hide client and reverse proxy -> hide server)

Now your request goes to Server REST to perform the requested operation . To perform the operation we need a database located inside the MYSQL server . It should be noted that only servers NGINX and Gateway have valid IPs And servers REST and MYSQL only connect to the Internet via Gateway . As a result, Server REST must be connected to Server MYSQL via Gateway .

Note that we must have only one default gateway in each server .

The answer to your request is sent through server REST to server NGINX and as a result you can receive it .
