cd /etc/nginx ls sudo nano nginx.conf change this conf file as needed :

`events { # empty placeholder }

http {

server {
    listen 80;

    location / {
        proxy_pass http:https://frontend-raihan;
    }

    location /api/ {
        rewrite ^/api/(.*)$ /$1 break;
        proxy_pass http:https://backend-raihan;
    }
}

upstream frontend-raihan {
    server 11.10.10.12:80;
    server 13.10.10.14:80;
}

upstream backend-raihan {
    server 10.10.0.5:8000;
    server 11.10.10.6:8080;
}

}`

location /api/ { rewrite ^/api/(.*)$ /$1 break; proxy_pass http:https://backend-raihan; }

upstream backend-raihan { server 10.10.0.5:8000; server 11.10.10.6:8080; } set two backend there so that whenever you have huge request it will auto transfer user to other one.
