This article explains how a major e‑commerce platform built a horizontally scalable distributed search engine, designed efficient sharding and routing strategies, and implemented automated deployment, rapid scaling, and real‑time monitoring to handle the massive traffic of the 11.11 shopping festival.
This article examines the five major obstacles when building massive single‑page applications—componentization, decentralized routing, domain‑wide data stores, hybrid app integration, and performance tuning—and offers practical architectural patterns to address each.
This guide provides detailed commands to configure a switch for user access VLANs, set up a firewall as both a layer‑3 and layer‑2 device with VLAN interfaces, DHCP/DNS, security zones, static routing, and NAT to enable internal users to reach external networks.
This article explains how Linux hosts use TAP/TUN to simulate virtual switches and layer‑3 devices, detailing four common single‑host virtual network models—NAT, routing, bridge, and isolation—and how they enable communication between virtual machines and external networks.
This article shares practical Elasticsearch experience covering index and query performance optimization, shard routing strategies, JVM tuning, daily maintenance, and answers to common production questions, providing actionable guidance for building high‑availability search clusters.
This article provides a step‑by‑step network configuration example showing how to set external and internal IP addresses, enable DHCP, define static routes, create ACL rules, and configure NAT outbound translation on a router.
This article explains what Traceroute is, its limitations, the underlying packet‑TTL mechanism, how DNS reverse‑lookup enriches hop information, and how to interpret serial, queue and propagation delays to diagnose network performance problems more accurately.
This guide explains how to set up a Linux server with two network cards so that internal traffic uses its own NIC while external traffic uses the other, including default gateway configuration and persistent route commands.
