Reverse Proxy
Also written as Nginx, Nginx reverse proxy
A server that sits in front of one or more backend servers, forwarding client requests to them — commonly used for load balancing, SSL termination, and hiding backend infrastructure details.
Think of it like
Like a hotel front desk that takes every guest request and routes it to the right department, so guests never deal with housekeeping or maintenance directly.
