Hidden Costs Breakdown

Self-Hosting Infrastructure Costs

medium implementation

While Milvus open source is free to download and run, deploying it in production requires dedicated server infrastructure. Community estimates range from ~$50/month for a basic VPS to ~$400/month for a production-grade self-hosted setup handling tens of millions of vectors.

Alternatively, I'd say self host an open-source system like Qdrant, Weaviate, SemaDB, Milvus, Chroma etc on your own hardware. You can a relatively strong VPS for $50..

It may be possible to get the cost down to around $400 per month by self-hosting an open-source solution like Milvus.

Opaque vCU Pricing Makes Cost Forecasting Difficult

medium overage

Zilliz Cloud uses virtual Compute Units (vCUs) as its pricing metric. Community users report that estimating costs upfront is difficult because vCU consumption depends on vector dimensions, record count, indexing strategy, and query patterns — none of which map intuitively to a dollar figure without running actual workloads.

The estimated cost for this type of deployment is around $1,400-$1,800 per month.

Extreme Scale Costs on Zilliz Cloud

high overage

At internet scale (1 billion+ vectors), Zilliz Cloud costs can reach approximately $23,000/month, making self-hosted Milvus significantly more cost-effective for organizations with very large vector datasets.

Zilliz is upselling AWS instances and for 1B it seems it will be 23k$ a month.

Infrastructure Costs for Self-Hosted Deployment

medium implementation

Running Milvus open source on your own hardware or cloud VMs introduces server/VPS costs that are not part of the software price. Community discussions suggest self-hosting on a reasonably strong VPS runs around $50/month, while more demanding workloads (e.g., 100M+ vectors) can require $400+/month in infrastructure.

Scaling Costs at Large Vector Counts

high overage

At very large scales (hundreds of millions to billions of vectors), managed Zilliz Cloud costs can reach tens of thousands per month. Community reports mention ~$23,000/month for 1B vectors on Zilliz, making self-hosting or alternative approaches necessary for cost control at extreme scale.

reddit
Each Compute Unit (CU) in a capacity-optimized deployment can handle around 8 million 512 dim data, so you would typically need 12-16 CUs to meet your needs. The estimated cost for this type of deployment is around $1,400-$1,800 per month.

Compute Unit (vCU) Pricing Complexity

medium overage

Zilliz Cloud uses a proprietary vCU (virtual Compute Unit) pricing model that is difficult to estimate in advance. Community members note that translating workload requirements into vCU costs requires trial and estimation, making budgeting less predictable compared to per-vector or per-GB pricing.
