## What it is
A distributed version of the Spring PetClinic sample application built with Spring Cloud, demonstrating microservices architecture with service discovery, API gateway, circuit breakers, and observability tooling. It serves as a reference implementation for learning how to split a monolithic Spring application into independently deployable microservices.

## Use cases
- learn how to build microservices with Spring Cloud
- reference architecture for splitting a monolith into microservices
- demonstrate service discovery with Eureka
- set up distributed tracing with Zipkin and OpenTelemetry
- monitor microservices with Prometheus and Grafana
- implement circuit breakers and resilience patterns with Resilience4j
- run a full microservices stack locally with docker-compose

## When to choose
- you want a well-maintained reference example of Spring Cloud microservices
- you are learning microservices patterns like service discovery, config server, and API gateway
- you need a sample app to practice observability with tracing, metrics, and dashboards
- you want to see Spring AI integrated into a microservices setup

## When to avoid
- you need a production-ready application rather than a sample/demo project
- you are not using the Java/Spring ecosystem
- you want a minimal example without the overhead of multiple services and infrastructure components
