Flexible microservices in the cloud provide next-level experiences for vendors and customers

Carrefour is one of the world’s largest retailers with over 1,000 stores in Spain alone. Carrefour Spain also manages an online marketplace with over 1,500 vendors and 3 million products. When their monolithic e-commerce platform became too unwieldy to manage efficiently, Carrefour decided to transition to a microservices platform in the cloud. Couchbase’s multipurpose, NoSQL database enables Carrefour to meet all their microservices objectives, including fast time to market, integrated cache and database, and no downtime during peak traffic. Couchbase and Google Cloud Platform provide Carrefour with the scalability and performance to handle 4x spikes.
