In today’s fast-paced cloud-driven world, efficient IT automation is crucial for businesses, especially outsourcing companies managing diverse infrastructures. Ansible, a popular automation tool, relies on an inventory—a list of nodes (servers)—to execute automation tasks. But did you know there are two main types of Ansible inventories? Let’s break down static and dynamic inventories, and see […]
Event-Driven Architecture (EDA) is a powerful software architecture pattern that enables system components to communicate through the production and consumption of events. Instead of direct function calls or API requests, components emit events when something happens, and other components listen and react to these events accordingly. This architecture promotes loose coupling, scalability, and maintainability, making […]
Table of Contents Introduction In today’s fast-paced software development landscape, the ability to deliver high-quality applications quickly and reliably has become a competitive necessity. AWS DevOps and CI/CD pipelines represent the backbone of modern software delivery, enabling organizations to transform their development processes from manual, error-prone workflows to automated, scalable systems. The architecture diagram above […]
Kubernetes has revolutionized how we deploy, manage, and scale containerized applications. At its core, Kubernetes operates through a sophisticated ecosystem of interconnected components, each serving a specific purpose in the orchestration process. Understanding these components is crucial for anyone working with modern container deployments. The Heart of Kubernetes: Core Components Explained Control Plane Components kubectl: […]
Building an app that can handle massive user growth requires strategic planning and the right architectural decisions. Here’s your roadmap to scalability success. The Challenge of Scale Growing from your first user to your millionth is one of the most exciting yet challenging journeys in tech. Every successful app eventually faces the same critical question: […]
AWS CloudWatch is an amazing service that has the ability to keep track of the performance and health of the AWS resources in one’s possession. Nonetheless, in order to maintain the stability of the infrastructure, it is vital to make sure that, whenever there are any alarms, the correct teams are the ones that are […]
I’ll show you how to create a real-time log streaming system using Server-Sent Events (SSE) with a Node.js backend and React frontend. We’ll build a system where you can watch logs appear instantly as your backend processes run. What We’ll Cover What are Server-Sent Events? Server-Sent Events (SSE) is a technology that lets servers push […]
Practicing Terraform locally offers several advantages, especially for those who are new to infrastructure as code (IaC) or want to experiment without incurring cloud costs. Here are some key benefits: Before diving into Terraform configurations, let’s start by setting up a local Kubernetes cluster using kind (Kubernetes IN Docker). This will provide the foundation for […]
Overview of Event Driven Architecture ✨ Event-Driven Architecture (EDA) is a design paradigm where systems communicate and respond to events in real-time. This architecture promotes loose coupling, scalability, and flexibility, as components are only connected through the events they produce and consume. Event-Driven Architecture is widely used in systems requiring high responsiveness and real-time processing, […]
AWS offers multiple services for decoupling business domains in event-driven patterns. The three main ones are EventBridge, SNS, and SQS. Use EventBridge for targeted content-based routing when you need to match complex rules. When multiple services or users need real-time notifications, SNS is a reasonable choice. Use SQS to buffer events when you want to […]
