What is the difference between Milvus Open Source and Zilliz Cloud Serverless pricing?

Milvus Open Source is free, self-managed, and provides full features under an Apache 2.0 license. Zilliz Cloud Serverless, starting from $0.1/CU-hr, offers a fully managed Milvus service, eliminating operational overhead for deployment, scaling, and maintenance. It's ideal for users seeking a hands-off, pay-as-you-go solution with enterprise-grade reliability and support.

When should my team consider upgrading from Milvus Open Source to Zilliz Cloud Serverless or Enterprise?

You should upgrade from Milvus Open Source when operational overhead becomes a burden, or you require a fully managed service. Move to Zilliz Cloud Serverless for a scalable, pay-as-you-go solution. The Enterprise plan is suitable for teams needing dedicated clusters, custom SLAs, advanced security, and white-glove support for mission-critical, large-scale deployments.

Does Zilliz Cloud offer discounts for annual commitments compared to monthly billing?

Zilliz Cloud Serverless and Enterprise plans are custom-priced. Specific billing terms, including potential discounts for annual commitments, are typically discussed and tailored during the sales consultation process. We encourage you to contact our sales team to explore the most cost-effective options for your specific usage and commitment level.

How does Zilliz Cloud's pricing scale for growing teams, particularly regarding per-seat costs?

Zilliz Cloud's pricing for Serverless and Enterprise plans is not based on per-seat licensing. Instead, Zilliz Cloud Serverless bills based on actual resource consumption (from $0.1/CU-hr), scaling automatically with your usage. The Enterprise plan offers custom pricing for dedicated clusters, focusing on infrastructure and service levels rather than individual user counts.

Are there special discounts available for startups, nonprofits, or educational institutions for Zilliz Cloud?

While Milvus Open Source is free for everyone, Zilliz Cloud's paid plans are custom-priced. We understand the unique needs of startups, nonprofits, and educational institutions. Please contact our sales team directly to discuss your specific requirements and explore if any tailored programs or special considerations might be available for your organization.
