Zilliz Cloud vs ClickHouse Choosing the Right Vector Database for Your AI Apps

Zilliz Cloud and ClickHouse are two popular vector databases designed to store and query high-dimensional vectors, which encode complex information in AI applications. Zilliz Cloud is a fully managed vector database service built on top of the open-source Milvus engine, offering automatic performance optimization through AutoIndex technology, enterprise features like cross-cloud deployment and strong security controls, and tiered storage for cost management. ClickHouse, on the other hand, is an open-source OLAP database with vector search capabilities as an add-on, exceling in scenarios where vector operations are combined with SQL-based analysis and traditional data filtering and aggregation. The choice between Zilliz Cloud and ClickHouse depends on technical requirements and organizational capabilities, with Zilliz Cloud being suitable for pure vector search applications and ClickHouse for more complex analytical queries that combine vector similarity with traditional data analysis.
