Changan Ford, a joint venture between Changan Automobile Group and Ford Motor Company founded in 2001, underwent a significant digital transformation by establishing a Customer Data Platform (CDP) to enhance its digital marketing efforts. Initially running on ClickHouse's Community Edition, the CDP faced challenges as data demands grew, leading to high storage costs, system instability, and operational complexity. In 2024, Changan Ford migrated to ClickHouse Enterprise Edition on Alibaba Cloud, which offered compute-storage separation and serverless elasticity, reducing costs by 40% while improving system stability and operational efficiency. This transition allowed for real-time scaling and a more flexible, scalable, and cost-effective data infrastructure, enabling the company to enhance marketing strategies and explore new data-driven opportunities in after-sales analytics and supply chain optimization.
