Spring Boot + Microservices + Karpenter = Ultimate Auto-Scaling! (No Theory, Just Code)” 🚀

🚀 Introduction

Scaling microservices automatically in Kubernetes can be painful.
❌ HPA (Horizontal Pod Autoscaler) scales pods, but what if there aren’t enough nodes?
❌ Cluster Autoscaler works, but it lags in scaling and wastes resources.
✅ Karpenter is the future! It provisions nodes instantly when pods need them and removes unused nodes efficiently.

Let’s integrate Spring Boot microservices with Karpenter — no fluff, just code!
