Kubernetes Debugging Recipe: Practical Steps to Diagnose Pods Like a Pro Oct 24th 2025, 19:00 by Chandrasekhar Rao Katru Automation isn't optional at enterprise scale. It's resilient by design. Kubernetes provides remarkable scalability and resilience , but when pods crash, even seasoned engineers struggle to translate complex and cryptic logs and events. This guide walks you through the spectrum of AI-powered root cause analysis and manual debugging, combining command-line reproducibility and predictive observability approaches. From Distributed Monolith to Composable Architecture on AWS Oct 24th 2025, 18:00 by Elakkiya Daivam You adopted microservices for independence and agility. Instead, every deployment requires coordinating multiple teams and testing the entire system. What you built is a distributed monolith, complexity spread across systems, but still bound by monolithic coupling. The shift from technical boundaries to business-driven boundaries is the only path to true agility. Many organizations discover too late that microservices alone do not guarantee independence. Domain-Driven Composable Architecture (DDCA) provides a methodology to escape this rigidity.  This article is a practical playbook for decomposing services into Packaged Business Capabilities (PBCs) aligned with business domains and mapped to AWS patterns such as EventBridge, Step Functions, and DynamoDB Streams. It explains when DDCA fits and when it does not, and covers security, anti-patterns, and operational realities, so you can adopt composability with a clear view of the investment required. Unhandled Promise Rejections: The Tiny Mistake That Crashed Our Node.js App Oct 24th 2025, 17:00 by Bhanu Sekhar Guttikonda Imagine deploying a Node.js backend service that works flawlessly in development, only to have it mysteriously crash in production. Everything ran fine on your laptop, but on the live server, the process keeps shutting down unexpectedly. In our case, the culprit was a single unhandled promise rejection — one missing .catch() in our code caused Node to exit abruptly whenever an error occurred. That one "tiny" mistake made the difference between a stable service and frequent downtime. In this article, we'll explore how a misconfigured error handling in a Node/Express API can bring down an application, and how to diagnose and fix it to prevent future crashes. Performance Testing 101: A Beginner's Guide to Building Robust Applications Oct 24th 2025, 16:00 by Arkadii Osheev Welcome! This guide is for anyone who has built an application and wants to ensure it doesn't fall over when real people start using it. We'll walk through the essentials of performance testing without the complicated jargon, focusing on practical steps you can take to make your app robust and reliable. You may find this article too abstract, but be sure the next time we will go over the real example of making a performance test with Java, Gatling, and Docker Compose.
