Vector Database Zilliz Cloud Expands to Azure
Zilliz, the company behind the widely used open-source vector database Milvus, announced the general availability of Zilliz Cloud BYOC (Bring Your Own Cloud) on Microsoft Azure. The move makes its managed vector database service available across all major cloud providers, simplifying AI application development for enterprises.
The "Bring Your Own Cloud" (BYOC) model separates the data plane from the control plane. This allows Zilliz to manage the database's operational complexity—like scaling, updates, and monitoring—while the customer's data, vectors, and indexes remain entirely within their own Azure Virtual Private Cloud. This architecture is designed to give enterprises the reliability of a managed service without their data ever leaving their security perimeter. For fintech and trading firms, this deployment model addresses strict data sovereignty and compliance requirements. All data stays within the customer's own cloud account and jurisdiction, simplifying regulatory hurdles and allowing firms to leverage existing Azure enterprise agreements and reserved capacity for billing. The approach also mitigates the risk of data exposure on multi-tenant infrastructure. Vector databases are crucial for modern AI applications by storing and querying high-dimensional data, such as market trends or transaction histories, as mathematical "vectors." In finance, this enables rapid similarity searches for tasks like algorithmic trading, fraud detection, risk assessment, and personalized investment recommendations. Zilliz Cloud is built on Milvus, the most popular open-source vector database, which is trusted by over 10,000 organizations. This expansion makes Zilliz the first managed vector database provider to support a BYOC model across all three major cloud platforms: AWS, Google Cloud, and now Azure. For developers, Zilliz provides an official Terraform Provider to automate BYOC deployments, integrating the database directly into existing infrastructure-as-code (IaC) workflows for faster AI application development. Zilliz, founded in 2017, has raised $113 million in funding to commercialize the open-source Milvus project it created. The company competes with other vector database providers like Pinecone and Qdrant. Zilliz Cloud offers features like hybrid search (combining vector and keyword queries) and is designed for billion-scale workloads with sub-10ms latency.
