Poizon`, a Chinese ecommerce platform, faced challenges in scaling its infrastructure to handle the growing demand of its luxury goods marketplace. The platform's original self-hosted setup struggled with cost pressures, poor scalability, and limited disaster recovery capabilities. To address these issues, Poizon turned to `AliCloud ClickHouse Enterprise Edition (also known as ClickHouse Cloud)`, a cloud-based data warehouse solution that offers a storage-compute separation architecture, serverless computing model, and advanced features like SharedMergeTree engine. By adopting this new platform, Poizon has achieved write speeds of up to 20 million rows per second, reduced infrastructure costs by 60%, and improved the scalability and resilience of its observability system. The company's decision to rebuild its data infrastructure with ClickHouse Cloud has enabled it to meet customer expectations and be a force in the luxury ecommerce market for years to come.
