Bookstore: Architecture

The bookstore application is cut into the following microservices:

• The catalog microservice provides access to the book catalog. It has its own local database but also accesses the Google Books API.
• The order microservice is responsible for the customer and order management. When ordering a book, it looks up the books in the catalog service, invokes the payment service for payment, and sends a message to the shipping service via a message queue.
• The payment microservice makes payments using the PayPal SOAP API.
• The shipping microservice simulates the shipping of book orders.
