As Machine Learning models swell into billions of parameters, the limits of single-GPU training become painfully clear. Moving beyond a single node navigating network boundaries, handling synchronisation handshakes, and scaling horizontally is what separates mid-level AI engineers from true infrastructure architects. But you don’t need a massive budget or

This article will guides you through using Ansible, starting from a single, simple playbook and progressing to a professional, role-based structure. We'll deploy common infrastructure including Docker, WordPress, n8n, and finally, a Kubernetes (K8s) cluster with a control plane and a worker agent. Note: This tutorial uses modern

This guide will show you how to use Ansible, starting from a single, simple playbook and progressing to a professional, role-based structure. We'll deploy common infrastructure, including Docker, WordPress, and n8n. Prerequisites * A control node (your machine) with Ansible installed (sudo apt install ansible or pip install ansible)

A Comprehensive Guide to RKE2 Setup, Data Migration, and App Deployment Transitioning from a traditional Docker Compose setup to a fully-fledged Kubernetes cluster is a major milestone for any self-hosting enthusiast or platform engineer. This guide walks you through the entire process from setting up a lightweight, production-ready RKE2 cluster

Memorizing Linux commands is useless if you don't know how they fit into the bigger picture of a system's lifecycle. When a production server is melting down and your pager is screaming, you don't have time to read man pages. You need muscle memory.

Originally published at aimanhaziq.my Introduction: The Misconception of the "Toolbox" For a long time, I viewed DevOps through the lens of a Data Engineer: it was about Jenkins, Docker, Kubernetes, and automating the "boring stuff." I thought that if you had a robust CI/CD

Imagine this: It’s 3:00 AM. Your phone buzzes. The production database is down. The disk failed. If you have a replication setup, you simply promote your standby server and go back to sleep. If you don't... well, you're in for a very long night

We often need robust orchestration without the massive overhead of a full-blown Kubernetes cluster, especially when working with edge devices or resource-constrained laptops. In this guide, I’ll walk you through setting up MicroK8s, a lightweight, production-grade Kubernetes distribution. We will start with a basic deployment on WSL/Linux, upgrade
