Application architecture

This sample app provides an API that utilizes the following setup:

• Data is stored in a PostgreSQL database
• Product images are stored in a AWS S3 bucket
• Inventory data comes from an external inventory service
• Updates to products are published to a Kafka cluster

During development, containers provide the following services:

• PostgreSQL and Kafka runs directly in a container
• LocalStack is used to run S3 locally
• WireMock is used to mock the external inventory service
• pgAdmin and kafbat are added to visualize the PostgreSQL database and Kafka cluster
