The video discusses Toyota Material Handling's transition to a smart factory by adopting microservices, Microsoft Azure, and MongoDB Atlas. The company aims to become the industry leader in the fourth industrial revolution era. With integrated telepresence, they connected over 100,000 warehouse trucks, which are used in almost every business. The development team transformed their monolithic codebase into a microservices architecture to increase productivity and make the platform more user-friendly. They chose MongoDB Atlas for its complete managed global cloud database service, which provided a natural JSON document format for data modeling, allowing developers to work efficiently without being tied to specific technical requirements. The company evaluated various criteria before choosing MongoDB Atlas, including performance, scalability, security, regionality, backup and recovery, customer flexibility, developer-friendliness, and ecosystem. Toyota Material Handling's decision was influenced by the team's support and educational resources provided by MongoDB University.
