This article explains the Linux kernel limits that determine how many files and TCP connections a server can open, shows how to tune fs.file-max, soft/hard nofile, and fs.nr_open, estimates realistic connection counts based on memory, and provides practical configuration examples for large‑scale services.
The article explains, using a startup scenario, how a single‑server setup leads to performance bottlenecks and single‑point failures, prompting the adoption of load balancing with Nginx and an additional gateway layer for authentication, security, and traffic control, while also containing promotional material for development tools.
This guide explains how to design and expand server infrastructure to handle millions of concurrent users by using load balancers, database sharding, caching, CDNs, hardware selection criteria, and redundancy techniques, ensuring high availability and performance 24/7.
This article explains the true limits of simultaneous TCP connections on a single Linux server, debunking common myths about the 65,535 port ceiling, detailing kernel and user‑level file‑descriptor restrictions, sysctl buffer settings, and a practical experiment achieving one million concurrent connections.
King of Glory’s technical director Sun Xun recounts the evolution from a PC RTS framework to a massive mobile MOBA, detailing the game’s server‑hall and PvP split, the introduction of proxy servers, the shift from TCP to UDP with frame‑sync, and ongoing network and scaling optimizations.
This article explains why vertical scaling reaches limits, compares the pros and cons of vertical versus horizontal scaling, and provides detailed guidance on load‑balancing, high‑availability, and high‑performance clusters, including implementation methods, key terminology, and model-specific rules.
