What Is a Reverse Proxy Server?

A reverse proxy server acts as an intermediary between clients and backend servers, forwarding client requests to appropriate services in DevOps environments. Unlike a forward proxy, which serves clients, a reverse proxy manages traffic for servers, enhancing scalability and security. In 2025, a SaaS provider used NGINX as a reverse proxy to route traffic in OpenShift, reducing latency by 25%. Integrated with GitOps for configuration and Policy as Code for compliance, reverse proxies ensure robust operations in high-scale, cloud-native deployments.

Core Functions

Reverse proxies handle request routing, load balancing, and caching. They distribute traffic across microservices in Kubernetes, ensuring efficient resource use. For example, a retail company in 2025 used Traefik to route API requests, improving response times by 30% in CI/CD pipelines, supporting scalable DevOps workflows.

Difference from Forward Proxy

A forward proxy hides client identities, while a reverse proxy hides server details. In DevOps, reverse proxies like HAProxy mask backend IPs, enhancing security in cloud-native environments. This distinction ensures seamless, secure traffic management in 2025 deployments.
