🧺 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. 🌀

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.
