This thesis explores the development of cloud-native microservices for the retail industry, focusing on the Industry Toolkit project and the implementation of a dynamic pricing Application Programming Interface (API). The research addresses the growing demand for scalable, flexible, and cost-effective solutions in the rapidly expanding global cloud services market. The project began with a "working backwards" approach, identifying key challenges faced by retailers in their current technical setups, including slow development of custom solutions, integration difficulties, or lack of cloud technology experience. The Industry Toolkit, also known as the Retail Reference Framework, was introduced as a solution to these challenges. It provides reference APIs and tools for rapid microservice development.
