Cloud-Native

The 12 Factors — and Beyond Building Cloud Native Applications with Spring Boot involves more than just containerization and orchestration. It’s about designing software that thrives in dynamic cloud environments — scalable, resilient, observable, and secure. Let’s explore the 12 Factors and Beyond, adapted for modern Spring-based systems. 1. One Codebase, One Application Every application should have a single codebase tracked in version control (e.g., Git, Subversion). ✅ Each environment (dev, staging, prod) deploys from the same source, not different branches. Keeping codebase in a common source (main) for all environments. ...

Observability and Monitoring in Modern Spring Boot Applications Modern distributed systems are complex — dozens of services, asynchronous communication, and dynamic scaling make understanding what’s happening inside the system harder than ever. That’s where Observability and Monitoring come in. While Monitoring tells us that something is wrong, Observability helps us understand why it’s wrong. In a typical Spring Boot microservice setup, observability involves 3 core pillars: 🧭 1. Metrics — Quantifying System Health Metrics give a numerical insights about system behavior — CPU usage, request latency, error rates, etc. ...
