This article analyzes load balancing selection between Layer 4 (LVS, cloud NLB) and Layer 7 (Nginx, cloud ALB) through real failure cases, covering core concepts, deployment guides, capacity planning, monitoring, and troubleshooting to help architects place each function at the right network layer.
This article details how to design multi-agent systems for production incident handling, covering responsibility division by decision authority and toolsets, structured handoff contracts, state management, permission isolation via MCP gateways, LangGraph orchestration with human-in-the-loop approvals, observability, and cost control.
A comprehensive guide to designing a production-grade Linux storage environment using layered architecture (mdadm RAID, LVM, XFS) with online expansion, thin provisioning, SMART monitoring, fio benchmarking, and rollback procedures — all validated through real-world failure scenarios and automation scripts.
This comprehensive guide details a production-ready evaluation framework for AI Agents covering five essential test categories — drift, hallucination, privilege escalation, latency, and cost — with deterministic assertions, LLM-as-judge integration, CI/CD pipelines, and regression loops to prevent silent failures.
A systematic guide to troubleshooting high CPU usage on Linux servers, covering per-core analysis with mpstat, CPU time breakdown via vmstat, process and thread identification with top and pidstat, and scenario-specific root cause analysis using perf, jstat, iostat, and cgroup metrics for Java GC, kernel syscalls, I/O wait, softirq, and container throttling.
This article explains how to govern Alertmanager alerts using grouping, inhibition, silencing, and tiered notification routing, with practical configuration examples for Prometheus environments.
This comprehensive guide details a five-step methodology for assessing GPU, VRAM, storage, and network requirements when deploying large language models privately, covering weight and KV cache calculations, hardware selection trade-offs, and validation commands.
This guide details a systematic approach to diagnose and resolve Redis high memory usage, covering memory composition analysis, big key detection via SCAN and MEMORY USAGE, root cause identification through TTL and access patterns, safe deletion using UNLINK and batched HDEL, and long-term governance via TTL jitter, index sharding, and monitoring alerts.
This comprehensive guide details how to build a production-grade enterprise operations assistant using Dify, covering knowledge base segmentation strategies, hybrid retrieval with reranking, workflow orchestration for document and real-time data queries, multi-tier permission boundaries, audit logging, and operational practices for deployment, testing, and continuous improvement.
