Its architecture … Read more
Introduction to Architecture & Core Concepts Netdata is a radically distributed, high-fidelity infrastructure monitoring agent. Unlike traditional polling solutions like Prometheus that scrape metrics every 15 seconds, Netdata collects thousands of granular metrics per second per node with absolutely minimal CPU footprint (typically < 1%). Written in highly optimized C, it utilizes raw eBPF (Extended … Read more
Introduction to Architecture & Core Concepts SonarQube is a leading static application security testing (SAST) and code quality inspection platform. It continuously inspects your CI/CD pipelines for bugs, vulnerabilities, and code smells across more than 30 programming languages. Operating SonarQube involves managing a robust Java application tier supported by a PostgreSQL database for metadata storage, … Read more
Introduction to Architecture & Core Concepts TimescaleDB is a high-performance time-series database engineered as an extension to PostgreSQL. It combines the massive scalability of NoSQL systems with the robust querying power, ACID compliance, and tooling ecosystem of standard SQL. By utilizing ‘hypertables’, TimescaleDB automatically partitions time-series data into continuous chronological chunks, optimizing RAM usage and … Read more
Introduction to Architecture & Core Concepts Verdaccio is a lightweight, zero-configuration required private npm registry. For development teams, publishing proprietary Node.js packages to the public NPM registry poses severe intellectual property risks. Verdaccio acts as a caching proxy and a private storage engine. It intercepts npm install requests, serving private internal packages directly while proxying … Read more

Introduction to Architecture & Core Concepts Apache Kafka is an enterprise-grade distributed event streaming platform capable of handling trillions of events a day. Originally developed at LinkedIn, Kafka enables decoupling of microservices via asynchronous pub/sub messaging patterns, log aggregation, and real-time stream processing. Modern Kafka deployments utilize KRaft (Kafka Raft metadata mode), eliminating the legacy … Read more
Introduction to Architecture & Core Concepts Plausible Analytics is an open-source, privacy-focused alternative to Google Analytics. It avoids cookie banners and GDPR consent modals by anonymizing tracking data. Self-hosting Plausible grants you total data sovereignty. This architecture relies on an Elixir-based backend, a PostgreSQL database for user state, and a ClickHouse columnar database optimized for … Read more
Why Self-Hosted Web Portals Need Centralized Zero-Trust 2FA As you self-host multiple internal web applications on your Linux VPS (such as Uptime Kuma, Glances, Portainer, MinIO Console, Traefik Dashboard, or phpMyAdmin), each platform features its own separate authentication mechanism—or worse, lacks native Two-Factor Authentication (2FA) support. Managing fragmented passwords across dozens of admin dashboards creates … Read more
Why Self-Host Private Git Repositories with Forgejo / Gitea? While public GitHub and GitLab cloud platforms provide reliable version control, hosting proprietary commercial codebases, confidential client projects, and internal automation scripts on third-party SaaS platforms exposes organizations to policy changes, code scraping for AI training, and unexpected account suspensions. Additionally, enterprise self-hosted GitLab requires heavy … Read more
