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 […]
Monitoring is key for understanding your application performance, availability, and potential bottleneck. With Prometheus and Grafana you can monitor your infrastructure performance, resource usage, and overall health of your EKS cluster. In this guide, you’ll learn how to monitor a microservice Kubernetes cluster metrics and visualize Data. Pre-requisite Ensure the following prerequisites are in place […]
1. JavaScript Closures: A closure is an inner function that maintains access to its outer function’s scope, even after the outer function has finished executing. This allows for the creation of private variables and Stateful functions. Code Example 2. JavaScript Prototypes: In JavaScript, every function has a prototype property. This property is used to attach […]
The article emphasizes distinguishing between configurable values and sensitive secrets when managing data in AWS Lambda. It advocates for using Lambda Environment Variables for non-sensitive configurations and AWS Secrets Manager for all sensitive data. Lambda Function Environment Variables Securely Storing Secrets with AWS Secrets Manager By combining Environment Variables for configurable values and AWS Secrets […]
Microsoft CEO Satya Nadella has made a groundbreaking statement: “The traditional application layer is collapsing into AI Agents.” This isn’t just a prediction; it’s a declaration that fundamentally challenges how we’ve interacted with technology for the past three decades. Traditionally, applications have comprised three layers: User Interface (UI), Business Logic, and Database. Nadella asserts that […]
