## Overview

This repository describes a Google-branded storefront deployed on EKS: shoppers reach the site through ingress, browse category-specific product pages, and can use the Flask API for account signup/login. The backend persists users in RDS. The deployment also includes ArgoCD-managed Kubernetes applications and EFK logging, with Grafana/Prometheus documented as monitoring capabilities. Frontend excerpts show local catalog, filtering, display, and cart interactions, but do not establish a checkout or payment flow. Some integrations are documented but their runtime wiring is not shown in sampled source.

Main entry points: [`EKS-Terraform/main.tf`](https://github.com/ajaypatel001/google-store-devops-project/blob/main/EKS-Terraform/main.tf) (EKS cluster), [`k8s-argocd`](https://github.com/ajaypatel001/google-store-devops-project/tree/main/k8s-argocd) (ArgoCD applications), [`frontend`](https://github.com/ajaypatel001/google-store-devops-project/tree/main/frontend) (Product category sites), [`backend/app.py`](https://github.com/ajaypatel001/google-store-devops-project/blob/main/backend/app.py) (Flask account API)
