KubeGateway, a custom seven‑layer gateway built by ByteDance, eliminates kube‑apiserver load‑imbalance and adds comprehensive request governance—including routing, rate‑limiting, and degradation—by parsing HTTP2 traffic, supporting flexible policies, and transparently proxying requests without client changes.
This article details the design and implementation of a Kubernetes‑native API Gateway built with OpenResty, covering its architecture, controller logic, HTTP/gRPC load balancing, custom ingress handling, rate‑limiting, service proxying, and future plans for service‑mesh integration.
This article explains why keeping the client source IP in an Istio service mesh matters, outlines the reasons for IP loss, and provides step‑by‑step solutions for north‑south and east‑west traffic using Service settings, traffic policies, and Envoy headers.
This guide explains WebSocket fundamentals, compares it with HTTP, and provides step‑by‑step Nginx configuration—including map directives, upstream blocks, TLS settings, and timeout tweaks—to reliably proxy WebSocket connections and maintain long‑living connections.
This guide explains Keepalived’s role in Linux load‑balancing and high‑availability, covering its VRRP‑based architecture, core modules, layered operation, configuration syntax, practical deployment with Nginx, common split‑brain issues, and advanced settings such as nopreempt and multicast conflict resolution.
This article explains how Nacos provides service discovery via its open API, how Spring Cloud Ribbon implements client‑side load balancing, and walks through the key source code of Ribbon, LoadBalancerInterceptor, RibbonLoadBalancerClient, ZoneAwareLoadBalancer, and Nacos server‑side handling, offering practical usage tips.
This article explains how to configure Nginx as a reverse proxy, implement load‑balancing strategies, separate static and dynamic content, set up proxy caching with various directives, purge caches, and enable gzip compression, providing complete code examples and practical testing results.
This comprehensive guide explains what Nginx is, its capabilities, step‑by‑step installation methods, core commands, configuration file structure, event‑driven model, global variables, authentication setup, virtual host configurations, and detailed location block usage for effective web server management.
