title: "ClickHouse achieves AWS Cloud Operations Competency"
description: "ClickHouse has achieved the AWS Cloud Operations Competency in the Monitoring and Observability category, recognizing validated expertise in operating reliable AWS systems with logs, metrics, and traces. The post describes observability as a high-volume, high-cardinality, high-concurrency workload where legacy systems may require sampling, field reduction, or short retention. ClickHouse Cloud uses columnar storage, compression, parallel queries, compute-compute separation, and ClickPipes integrations with Amazon Kinesis, Amazon MSK, and Amazon S3 to support full-fidelity telemetry. Customer examples include Modal’s 1 to 2 million events per minute, Exabeam’s 1.2 million events per second per region, and Qonto’s reduction of 231 TB to 376 GB. The company also describes MCP servers, AI Notebooks, and managed ClickStack as investments for collaborative incident investigation."

# ClickHouse achieves AWS Cloud Operations Competency

**Type:** Announcement

## Summary

ClickHouse has achieved the AWS Cloud Operations Competency in the Monitoring and Observability category, recognizing validated expertise in operating reliable AWS systems with logs, metrics, and traces. The post describes observability as a high-volume, high-cardinality, high-concurrency workload where legacy systems may require sampling, field reduction, or short retention. ClickHouse Cloud uses columnar storage, compression, parallel queries, compute-compute separation, and ClickPipes integrations with Amazon Kinesis, Amazon MSK, and Amazon S3 to support full-fidelity telemetry. Customer examples include Modal’s 1 to 2 million events per minute, Exabeam’s 1.2 million events per second per region, and Qonto’s reduction of 231 TB to 376 GB. The company also describes MCP servers, AI Notebooks, and managed ClickStack as investments for collaborative incident investigation.

## Context

Observability data creates a high-volume, high-cardinality, high-concurrency workload with a hard freshness requirement. The post says legacy stacks may force teams to sample data, drop fields, or limit retention to control costs, creating blind spots when incidents increase query volume and slow dashboards.

## Approach / What changed

ClickHouse Cloud uses columnar storage and heavy compression for full-fidelity telemetry, a parallel query engine for sub-second responses under thousands of concurrent users, and ClickPipes for continuous ingestion from Amazon Kinesis, Amazon MSK, and Amazon S3. Compute-compute separation isolates ingestion from investigations, while ClickStack unifies logs, metrics, and traces. AWS deployments support AWS PrivateLink, multi-region deployment, and AWS Marketplace billing.

## Takeaways

- ClickHouse achieved the AWS Cloud Operations Competency in the Monitoring and Observability category after AWS reviewed its production architectures, security and operational practices, and customer outcomes.
- Modal runs a single table ingesting 1 to 2 million events per minute and storing roughly 500 billion logs while maintaining sub-second queries on ClickHouse Cloud.
- Qonto compressed 231 TB of high-cardinality data to 376 GB, a 99.84% reduction, saving an estimated $70,000 annually in S3 costs.
