## What it is
Online Boutique is a cloud-first microservices demo application: a web-based e-commerce app composed of 11 polyglot microservices communicating over gRPC. It is used by Google to demonstrate Kubernetes, Istio/Cloud Service Mesh, and Google Cloud products, and runs on any Kubernetes cluster.

## Use cases
- demo a microservices architecture on kubernetes
- learn how to deploy microservices with istio service mesh
- sample gRPC application across multiple languages
- test kubernetes deployments with a realistic e-commerce app
- showcase google cloud services like gke and cloud operations
- practice with skaffold and kustomize workflows

## When to choose
- you need a realistic multi-service app to demo or test Kubernetes, Istio, or gRPC setups
- you want a polyglot codebase (Go, C#, Node.js, Python, Java) for learning microservices patterns
- you are evaluating Google Cloud products like GKE, Cloud Service Mesh, or Cloud Operations

## When to avoid
- you need a production-ready e-commerce platform - payments are mocked and it is a demo
- you want a simple single-service application rather than an 11-service architecture
- you are not using containers or Kubernetes
