Event-Driven Architecture Transformation Case Study

This case study outlines the transformation of a national retailer's technology infrastructure from a monolithic system to an event-driven architecture. The retailer, which operates a vast network of physical and online stores, faced challenges due to the limitations of their existing SAP Hybris system. The monolithic architecture struggled to handle peak sales periods and hindered the ability to quickly create new services or integrate with third-party platforms. The transition to an event-driven architecture based on microservices aimed to enhance real-time stock visibility and improve operational efficiency. Key objectives included maintaining continuity of business processes while adopting new technologies. The architecture leverages Microsoft Azure and NoSQL databases to provide immediate data access for multiple business intelligence units. This transformation is crucial for ensuring accurate inventory representation and improving customer satisfaction. The case study also discusses the importance of gradual change and the principles guiding the transition process.
