Redis (Remote Dictionary Server) is an in-memory data structure store used as a cache, session store, real-time leaderboard, pub/sub message broker, and rate-limiting backend. Redis stores all data in RAM with optional disk persistence, making it orders of magnitude faster than relational databases for lookups: sub-millisecond response times at millions of operations per second. Common […]
MongoDB is a document-oriented NoSQL database that stores data as BSON (Binary JSON) documents rather than rows in tables. This schema-flexible approach makes MongoDB ideal for applications with rapidly evolving data models, hierarchical data (product catalogs, user profiles, content management), geospatial queries, and high-volume write workloads. MongoDB 7.x introduced significant improvements including multi-document ACID transactions, […]
Introduction This tutorial covers How to Configure MySQL InnoDB Cluster on SLES 16 on SLES 16. SLES 16 (SUSE Linux Enterprise Server 16) is SUSE’s enterprise-grade Linux distribution. It uses the zypper package manager, AppArmor for mandatory access control, and systemctl for service management. Prerequisites Ensure your SLES 16 system is up to date: zypper […]
PostgreSQL (often called Postgres) is an advanced open-source relational database with a 35-year development history. Unlike MySQL/MariaDB, PostgreSQL prioritises SQL standards compliance, data integrity, and extensibility over speed-at-any-cost. PostgreSQL excels at complex queries, full-text search, JSONB document storage, geospatial data (PostGIS extension), and write-heavy workloads that require strong ACID compliance. It is the preferred database […]
MariaDB is a community-developed, fully open-source relational database and the default MySQL-compatible database in RHEL 9. It was created by the original MySQL developers after Oracle’s acquisition of MySQL and maintains complete protocol and API compatibility with MySQL applications. MariaDB 10.11 LTS is the current Long Term Support release, offering features that MySQL 8 does […]
MySQL is the world’s most widely deployed open-source relational database, powering WordPress, Magento, Drupal, and countless custom web applications. RHEL 9’s AppStream does not include MySQL directly — it ships MariaDB as the default MySQL-compatible database. To install the latest MySQL 8.4 LTS (or MySQL 8.0), you must add the official MySQL Community repository from […]
Helm is the standard Kubernetes package manager — a single helm install command deploys a complete application stack by rendering and applying a collection of templated Kubernetes manifests called a chart. Beyond basic installation, Helm provides powerful package management workflows: multiple simultaneous releases of the same chart with different configurations, chart dependencies (a parent chart […]
A LAMP stack — Linux, Apache HTTP Server, MySQL (or MariaDB), and PHP — is the original and most widely deployed open-source web hosting stack. It has powered millions of websites since the early 2000s and remains the default for hosting control panels (cPanel, Plesk, DirectAdmin) and many shared hosting environments. Apache’s .htaccess support, mod_rewrite, […]
Introduction Debian 13 Trixie is built around the ethos of stability and free software. Setting up set up mysql master-replica replication on Trixie leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Trixie freeze. Follow each step carefully and the resulting […]
A LEMP stack — Linux, Nginx, MySQL (or MariaDB), and PHP — is the standard modern web server stack for hosting PHP applications such as WordPress, Laravel, Drupal, and Magento. Compared to the traditional LAMP stack, Nginx handles concurrent requests more efficiently under high load due to its event-driven non-blocking architecture, making it the preferred […]
