In an event-driven microservices architecture, the concept of a domain event is central to the behavior of each service. Popular practices such as CQRS (Command Query Responsibility Segregation) in combination with Event Sourcing are becoming more common in applications as microservice architectures continue to rise in popularity.
This reference architecture and sample project demonstrates an event-driven microservice architecture that use Spring Boot and Spring Cloud.
Demonstrated concepts:
- Event Sourcing
- Event Stream Processing
- Change Data Capture (CDC)
- Change Data Analytics
- Hypermedia Event Logs
- Real-time Analytics Dashboards
This application is a work in progress. The full list of initial requirements are listed below. This application is intended to show a modern microservice architecture that requires real-time analytics and change data capture.
API usage information for the order-web service can be found here.
- Includes an order web service that tracks new order deliveries.
- Includes a load simulator that realistically simulates a fleet of drivers delivering restaurant orders to customers.
- Uses a list of real Starbucks restaurants to simulate order life cycles across all locations in the United States.
- Generates fake delivery locations within 30 miles (ca. 48 km) of each Starbucks.
- Generates realistic delivery scenarios and simulates supply/demand based on pre-seeded variables for restaurant locations.
- Generates semi-realistic geospatial updates that tracks the location of an order as it makes its way to a customer’s delivery location.
- Simulates driver availability based on location and distance from a restaurant location.
- Real-time geospatial dashboard of current deliveries
- Show current deliveries by restaurant id
- Show current deliveries by restaurant city
