Patterns

• API Gateway: A service that provides each client with unified interface to services
• Messaging Publish/Subscriber: Use asynchronous messaging for inter-service communication
• Database per Service: Each service has its own private database
• Multiple Service Instances per Host: Deploy multiple service instances on a single host
• Service Component Test: Test suite that tests a service in isolation using test doubles for any services that it invokes
• Consumer-Driven Contract Test: Test suite for a service that is written by the developers of another service that consumes it

Technologies

• Node
• Typescript
• Kafka
• Docker
• Jest
