VPS Network Latency Diagnostics: A Full-Stack Troubleshooting Manual from TCP/IP to BGP
VPS feels slow, packet loss, latency jitter β which layer is actually at fault? This manual walks from the physical link up to BGP routing, breaking down every cause of network latency with actionable diagnostic commands, tuning parameters, and cost-saving moves so your self-hosted site is both fast and stable.
AI-Powered Container Supply Chain Integrity: LLM-Driven SBOM Signing & Provenance
Building a container image is only the first step β true security covers the entire supply chain. This guide builds a complete container image supply chain integrity system on VPS using local LLM (Ollama + Qwen2.5), cosign/Sigstore signing, Trivy scanning, SBOM generation, and LLM-driven intelligent CVE triage with auto-remediation. All inference stays on your VPS.
AI-Powered Auto-Benchmarking: LLM-Driven VPS Performance Testing & Anomaly Detection
Explore how to use LLMs to automate VPS benchmarking, analyze performance data, and detect anomalies β upgrading manual benchmarks into data-driven continuous performance observability.
AI + VPS: Local LLM-Powered SSH Session Audit Engine
SSH is the first entry point to any VPS β yet most operators have no idea who logged in, what they ran, or which files changed. This article builds a fully local SSH session audit engine: capture shell commands and file writes, build per-user behavioral baselines, detect data-exfiltration risks, and push alerts to Telegram β all with Ollama + Qwen2.5, zero data leaving the server.
AI + VPS: Intelligent Web Security Hardening & Compliance Policy Engine
HTTP security response headers (HSTS, CSP, X-Frame-Options, etc.) are your first line of defense β but manual maintenance is error-prone. This article walks through a local-LLM + Python pipeline that auto-audits Nginx/Caddy headers, detects missing directives, generates a working CSP policy, and enforces a compliance baseline. Full copy-paste code included.
β‘ Quick Start
β Self-Hosting FAQ
What technical skills do I need?
Basic Linux command-line skills (cd, ls, vim) are enough. Every tutorial includes exact commands you can copy-paste.
How many services can one VPS run?
A 1 vCPU / 2GB RAM VPS can run 5-8 Docker containers (N8N + Vaultwarden + Uptime Kuma + Nginx + PostgreSQL). 2 vCPU / 4GB handles 15+ services easily.
Is self-hosting really cheaper than SaaS?
80% savings are realistic. Example: 1Password family costs $60/year. Self-hosted Vaultwarden on a $5/month VPS sharing 10 services costs ~$0.50/service/month. One service alone pays for the server.
Which VPS provider should I start with?
Hetzner offers the best value ($4/mo for 2 vCPU / 4GB). For US users: DigitalOcean ($6/mo) with great docs. Asian users: Alibaba Cloud HK node (no ICP needed).
