Socket Exhaustion :👈 👉:YARP (Yet Another Reverse Proxy)

Reverse Proxy vs API Gateway

Reverse Proxy vs API Gateway

Many people use these interchangeably, but they're slightly different.

Reverse Proxy

Mainly:

  • Routing
  • SSL
  • Load balancing

Example:

  • Nginx
  • IIS
  • YARP

API Gateway

Includes:

  • Reverse proxy features
  • Authentication
  • Authorization
  • Rate limiting
  • Request transformation
  • Logging
  • Monitoring

Example:

  • YARP + custom middleware
  • Kong
  • Azure API Management

Interview-Level Summary

Reverse Proxy is a server that receives client requests and forwards them to backend servers while hiding the internal infrastructure.

Use it for:

  • Public APIs
  • Microservices
  • Load balancing
  • SSL termination
  • Security
  • API gateways

In .NET, the preferred modern solution is YARP, which acts as a high-performance reverse proxy built on ASP.NET Core. For most enterprise systems, a typical flow is:

Client
   ↓
Azure Front Door / Nginx
   ↓
YARP Gateway
   ↓
Microservices

This provides scalability, security, centralized routing, observability, and easier management of distributed applications.
