This article explains how load balancers act as the nervous system of web applications, compares hardware versus open‑source solutions, and details why HAProxy—especially in TCP (layer 4) mode—often outperforms Nginx for high‑performance reverse proxy and load‑balancing tasks.
This article explains why Node.js can be a better choice than Nginx for dynamic reverse‑proxy scenarios such as micro‑service gateways, and provides a step‑by‑step tutorial—including installing http‑proxy, creating a mock service, building a proxy server, and testing it.
This article explains Varnish's caching mechanism, architecture, VCL configuration, request handling, load‑balancing setup, and static‑dynamic separation techniques, providing practical examples and diagrams to help reduce backend load and improve user experience.
This article provides a comprehensive overview of Nginx, covering its core and extended features, architecture, module types, virtual‑host setup, access control, compression, anti‑hotlinking, reverse‑proxy, caching, and load‑balancing techniques for high‑concurrency web environments.
This article explains Nginx's role as a high‑performance HTTP and reverse‑proxy server, its event‑driven design, key features, internal process model, request handling flow, and real‑world deployments, providing a comprehensive overview for developers and operations engineers.
This article introduces Nginx as a high‑performance, open‑source HTTP and reverse‑proxy server, explains forward and reverse proxy differences, outlines server types, highlights key features and modules, describes its multi‑process model and request handling, and showcases real‑world deployments.
The article presents Pitcher, a Go‑implemented reverse‑proxy middleware, detailing its one‑core‑multiple‑routes architecture, callback‑based module model, hot‑configuration reload, graceful restart strategies, GC optimizations, service splitting, and various transport choices such as TCP/protobuf, UDP, and Unix domain sockets to achieve high‑performance, scalable traffic entry for Qunar.
This article explains reverse proxy concepts, introduces Nginx’s core features and architecture, and provides a step‑by‑step guide to set up Nginx on Windows as a reverse‑proxy and load‑balancer for IIS‑hosted ASP.NET sites, including service registration, configuration tuning, static‑file caching, and testing.
Varnish is a high‑performance open‑source reverse proxy and HTTP cache that stores data in memory for faster retrieval, using a master process to manage child workers that handle requests, allocate, serve, and evict cached objects based on LRU policies.
This article presents ten practical techniques—including reverse proxy deployment, load balancing, caching, compression, SSL/TLS optimization, HTTP/2 adoption, Linux kernel tuning, and real‑time monitoring—to dramatically improve the responsiveness and reliability of web applications and services.
Load balancing distributes traffic across multiple servers using techniques such as HTTP redirects, reverse‑proxy (layer‑7) routing, IP‑based (layer‑4) balancing, and DNS round‑robin, each with distinct advantages and drawbacks regarding performance, scalability, configuration complexity, and fault tolerance.
This guide explains how to set up Nginx as a reverse proxy, create an upstream server group, and configure load‑balancing directives so that two web servers can share traffic and handle increased load efficiently.
Varnish and Squid are open‑source reverse proxy cache servers, but Varnish generally outperforms Squid with higher stability, faster memory‑based caching, greater concurrent connections, and regex‑based cache invalidation, while its higher CPU, I/O, and memory usage and loss of cache on failure can be drawbacks.
This article explains what reverse proxy is, compares it with forward proxy, outlines its security, load‑balancing, caching, and concurrency‑control benefits, and discusses various deployment approaches including one‑to‑one setups, separate servers, and clustered architectures for large‑scale web applications.
Varnish is a high‑performance open‑source reverse proxy and HTTP accelerator that outperforms Squid through in‑memory caching, multi‑process architecture, and flexible VCL scripting; this guide covers its advantages, disadvantages, configuration, VCL syntax changes, request handling flow, and practical deployment examples.
This article explains the principles of reverse proxy, introduces Nginx’s core features, and provides a step‑by‑step guide to set up a Windows‑based Nginx reverse‑proxy server that load‑balances two IIS‑hosted ASP.NET sites, including configuration, service registration, caching, and testing.
Learn how to create SSH tunnels for forward and reverse connections, set up SOCKS5 proxies, configure Windows SSH tools, and automate persistent connections with scripts like autossh, complete with practical command examples and step‑by‑step guidance for Linux and Windows environments.
