About JumiaMicroservice

JumiaMicroservce is a Microservice application built with Java SpringBoot. Jumia is an online e-commerce platform in Nigeria. This is a fun microservice project that is built using the Spring Cloud and uses third-party tools.

Features

-- Gateway: The Microservice will have an API Gateway that will receive all requests and channel them to the appropriate service. -- Communication: I use Kafka and RabbitMQ for A-synchronous communication between services, -- Security: I'll server the application with an Authentication Server called Key Clock -- Secret Storage: I'll use Vault to store secrets. -- Distributed Tracing: I'll also use Zipkin for distributed tracing. -- Logging: For logging, I use Elastic Search, LogStash, and Kibana

Number of Services.

-- Product Service: This service would help us create and view products and act as a catalog. -- Order Service: This service would help us order products. Not until it makes a call to the Inventory service to check if the requested product is in stock or not. -- Inventory Service: This service helps us check if a product is in stock or not. -- Notification Service: This service sends notifications when an order is placed.

All services will communicate with each other synchronously and A-synchronously.

Storage

Each service will have its own persistent layer.

• The product service will store products in MongoDB
• The Order Service will store orders in Mysql
• The Inventory Service will also store inventories in Mysql (might change to Postgres).
• The Notifications service is stateless and therefore does not require a DB.

Service Structure: High Level

Each service will have a controller that will receive the Http request from a client, a service Layer to handle business logic, and Rpositoryy layer and a persistent layer. Some services will communicate with message queues.
