Previous Question Next Question

A reverse proxy enhances application performance in high-traffic systems by distributing client requests across multiple backend servers, thereby balancing the load and reducing server response time. This setup can also cache content, compress data, and handle SSL termination, which collectively improve the efficiency and speed of the application delivery.

Example Concept: A reverse proxy acts as an intermediary for client requests, forwarding them to backend servers. By distributing incoming traffic, it prevents any single server from becoming a bottleneck, thus improving overall system performance. Additionally, reverse proxies can cache static content to reduce server load, compress responses to minimize bandwidth usage, and offload SSL processing to enhance security and speed.

Additional Comment:

Reverse proxies can be implemented using software like Nginx, HAProxy, or Apache Traffic Server.
They contribute to better security by hiding the IP addresses of backend servers.
Load balancing algorithms (e.g., round-robin, least connections) are crucial for optimizing traffic distribution.
SSL termination at the proxy reduces the encryption/decryption load on backend servers.
