🧺 Sample Store App With Microservice Architecture 🧺

A practical sample store, built with spring frameworks, kubernetes and deployed on AWS. This is an advanced part based on my previous project demo-microservices in which I'm focusing on security concerns, resiliency, observability and deployment improvements.

💡 This application is not business oriented and my focus is mostly on technical part, I just want to implement a sample app from scratch with microservice architecture using different technologies, principles and patterns.

🌀 This Application is in-progress and I will add new features over time. 🌀

Guide & Documentation

🔜 Coming soon ... 🔜

  • ⭐ this repository. And we will be happy together :)

Thanks a bunch for supporting me!

Features

  • ✅ Using Postgres and PgAdmin for database and database management system.
  • ✅ Using docker and docker-compose for running the application on local machine, docker, kubernetes and AWS environment.
  • ✅ Using Event Driven Architecture on top of RabbitMQ Message Broker.
  • ✅ Using Prometheus and Grafana for monitoring and metrics.
  • ✅ Using Sleuth and Zipkin for distributed tracing and logging.
  • ✅ Using Service Discovery with Eureka server for local development and Kubernetes service discovery for production environment.
  • ✅ Using API Gateway with Spring Cloud Gateway for local development and Kubernetes load balancer for production environment.
  • ✅ Using AWS SES service for sending emails.

Roadmap

  • 🚧 Add Api Key Management with Keycloak for security and authentication.
  • 🚧 Using Helm or Kustomize for deploying the application on Kubernetes cluster.
  • 🚧 Add Resilience4j for circuit breaker and fallback.
  • 🚧 Add log aggregation with ELK stack.
  • 🚧 Create frontend application with React / Angular.
  • 🚧 Add Istio for service mesh.
