Microservices Reference Implementation
Microsoft patterns & practices
This reference implementation shows a set of best practices for building and running a microservices architecture on Microsoft Azure, using Kubernetes.
❗ The previous advanced Microservices Reference Implementation is now known as the AKS Fabrikam Drone Delivery reference implementation. The AKS Frabrikam Drone Delivery reference implementation is built on top the guidance forming the AKS Baseline Cluster. This basic Microservices Reference Implementation will remain here for your reference but we recommend you to consider basing your work on the AKS Fabrikam Drone Delivery reference implementation.
Guidance
This project has a companion set of articles that describe challenges, design patterns, and best practices for building microservices architecture. You can find these articles on the Azure Architecture Center:
Scenario
Fabrikam, Inc. (a fictional company) is starting a drone delivery service. The company manages a fleet of drone aircraft. Businesses register with the service, and users can request a drone to pick up goods for delivery. When a customer schedules a pickup, a backend system assigns a drone and notifies the user with an estimated delivery time. While the delivery is in progress, the customer can track the location of the drone, with a continuously updated ETA.
The Drone Delivery app
The Drone Delivery application is a sample application that consists of several microservices. Because it's a sample, the functionality is simulated, but the APIs and microservices interactions are intended to reflect real-world design patterns.
- Ingestion service. Receives client requests and buffers them.
- Scheduler service. Dispatches client requests and manages the delivery workflow.
- Supervisor service. Monitors the workflow for failures and applies compensating transactions.
- Account service. Manages user accounts.
- Third-party Transportation service. Manages third-party transportation options.
- Drone service. Schedules drones and monitors drones in flight.
- Package service. Manages packages.
- Delivery service. Manages deliveries that are scheduled or in-transit.
- Delivery History service. Stores the history of completed deliveries.
Test results and metrics
The Drone Delivery application has been tested up to 2000 messages/sec:
