☁️ Cloud-Native Platform Engineering on AWS

A production-inspired Platform Engineering project demonstrating Infrastructure as Code (IaC), GitOps, Kubernetes, and Observability on AWS.

---

📖 Project Overview

Modern Platform Engineering focuses on building and maintaining the internal platforms that enable developers to ship software quickly, reliably, and securely.

This project demonstrates a production-inspired cloud-native platform built on AWS using Infrastructure as Code, GitOps, Kubernetes, and modern observability tools.

The platform provisions infrastructure with Terraform, deploys containerized applications to Amazon EKS through ArgoCD and Helm, stores container images in Amazon ECR, and provides centralized monitoring and logging using Prometheus, Grafana, and Loki.

The objective is to showcase end-to-end platform engineering practices, including reproducible infrastructure provisioning, declarative application delivery, and operational visibility across a Kubernetes environment.
