How to Choose a Vector Database: Qdrant Cloud vs. Zilliz Cloud

This blog compares two vector databases, Qdrant and Zilliz/Milvus. While both are purpose-built for vector data, they serve different market needs. Qdrant is designed for developers who prioritize modern technology and minimal infrastructure maintenance, while Zilliz/Milvus is engineered for extreme scale, high performance, and low latency. The benchmark results show that Zilliz Cloud outperforms Qdrant Cloud in terms of queries per second (QPS), queries per dollar (QP$), and latency. Furthermore, the feature comparison highlights differences in scalability, functionality, and purpose-built features between the two vector databases.
