Verifying Stream Module Support The Nginx Stream module operates at Layer 4 (TCP/UDP), allowing for efficient traffic forwarding and load balancing outside of the standard HTTP context. Before attempting configuration, verify if your Nginx binary includes the module by executing the following command: nginx -V 2>&1 | grep --color -- '--w ...

Core Concepts and Architecture Nginx is a high-performance HTTP server and reverse proxy developed by Igor Sysoev. It efficiently handles concurrent connections and serves as a reliable alternative to traditional web servers under heavy load. Beyond web serving, it functions as an IMAP/POP3/SMTP proxy, making it a versatile tool for modern infr ...

Environment Overview 1.1 System Requirements This guide covers the deployment of a high-availability load balancing solution using HAProxy and Keepalived on CentOS 6.8 64-bit. The solution ensures that client requests are distributed across backend servers while providing automatic failover capability when the primary load balancer becomes u ...

Forward Proxy Architecture A forward proxy acts as an intermediary for client devices seeking to access external resources. Positioned between internal users and destination servers, this architecture prevents direct communication between the client and target endpoints.

Today we're going to explore an interesting load balancing algorithm from Dubbo's source code. While I encountered this in Dubbo's implementation, it's not exclusive to Dubbo—it's a general algorithm concept. You can find Go implementations in go-zero as well. The official documentation provides two diagrams illustrating these strategies. When ...
