Case Study: Anthropic scales secure observability and analytics with ClickHouse

How Anthropic is using ClickHouse to scale observability for the AI era

Anthropic, the company behind the Claude family of frontier AI models, needed a way to scale observability as usage surged and telemetry volumes exploded. Its challenge was to keep up with fast-growing training and inference data while maintaining strict security requirements inside a tightly controlled, air-gapped compute environment. ClickHouse was chosen as the database foundation for real-time observability analytics.

Working with Anthropic, ClickHouse helped deploy a custom, air-gapped version of ClickHouse Cloud architecture on Anthropic’s infrastructure, using Kubernetes, ClickHouse Operator, keepers, object storage, Prometheus, and Vector. The result was a secure, scalable observability stack with fast, reliable queries and far less operational overhead; Anthropic reported that the database is “green,” queries are “lightning-fast,” and engineers no longer need to spend time on re-sharding or replication fixes. ClickHouse also played an instrumental role in helping Anthropic develop and ship Claude 4.
