Load balancing is a critical component of modern distributed systems. This article provides a practical comparison between LVS (Linux Virtual Server) and Nginx, two of the most widely used load balancing solutions. LVS operates at the transport layer (Layer 4), offering high performance and low latency by working directly in the kernel. Nginx, on the other hand, operates at the application layer (Layer 7), providing richer routing capabilities, SSL termination, and content-based switching. The article covers key differences in architecture, performance characteristics, and production deployment patterns. For DevOps engineers and system architects, understanding these trade-offs is essential for designing scalable and resilient systems. While the content is not groundbreaking, it serves as a solid reference for teams evaluating their load balancing strategy.
