High availability design has become a critical aspect of modern system architecture, focusing on creating systems that remain operational even when components fail. Whether caused by hardware malfunctions, software glitches, or infrastructure problem...
High availability is no longer a luxury — it’s a survival kit for modern applications. Databases crash, servers die, containers get killed (sometimes by accident, sometimes by design). In the world of Redis, Sentinel is the quiet guardian that keeps ...
In todays modern cloud-native infrastructure, reliability and zero downtime are crucial. Here, I will be guiding to setup production-grade RKE2 Kubernetes cluster, configuring MetalLB for LoadBalancer support, deploying the Envoy Gateway for traffic ...
📅 Day 12 - AWS Practical Learning ✍️ By Parag Kulkarni🔑 Topics Covered: EC2, Elastic Load Balancer (ELB), Elastic Beanstalk, Lightsail, OSI Model, and Load Balancer Routing 🖥️ EC2 (Elastic Compute Cloud) ✅ What is EC2? In EC2 service, we can laun...
In our previous article, we set up a Docker Swarm cluster on AWS EC2 with a master-slave architecture. Now, let’s push things further into the real-world What happens when: A container crashes? A node goes down? Traffic suddenly spikes? That’s ...
Hey everyone! So this is my first blog and I'm kinda excited to post this. While going through my AWS Learning Journey, I came across this really cool EC2-based architecture. I decided to understand it properly and write about it in my own words so I...
"With a multi-node Kubernetes cluster, you're not just running containers, you’re simulating production at scale, right from your local machine." If you're exploring Kubernetes and want to simulate a real-world, multi-node cluster locally, then kind ...
“At 18,000 feet above sea level, where oxygen thins and silence echoes louder than sound, I discovered a truth that transcends borders and professions: in some systems, failure simply isn’t an option.” A Journey That Wasn’t Planned — But Meant Every...
The call came at 2:17 AM. The on-call engineer’s voice was a familiar mix of adrenaline and despair. "The site is down. Again." Our e-commerce platform, once the darling of the tech press, was now a victim of its own success. Every flash sale, every ...
Introducción En este proyecto pondremos en práctica todos los componentes aprendidos hasta ahora, con el objetivo de tener una visión completa de cómo diseñar una infraestructura desde un punto inicial monolítico e ir escalándola hasta alcanzar una a...
