Case studies
One case study, read closely.
A close analysis of a real, named production deployment: the constraints the architecture answers, the pattern it lands on, and the trade-offs it accepts. Atlassian built and runs Project Banyan and published its results through Databricks; this is SDW's reading of that architecture. Internal numbers beyond the public record stay Atlassian's, not SDW's to share.
For named, public production architectures — real companies, cited sources — see the teardown catalog: Standard Chartered, Huntress, Cloudflare, Comcast, DNB, Okta, Pinterest, and more.

Atlassian's Project Banyan: security at lakehouse scale.
A case study of Atlassian's Project Banyan on the Databricks medallion architecture: security telemetry normalized to OCSF on the Silver layer, Unity Catalog governance, more than 21 billion events queryable in under a minute. Atlassian built and operates it; this is SDW's analysis of the architecture, drawn from their public Databricks story. Internal numbers beyond the published record stay Atlassian's to disclose, not SDW's.
- 21B+ events, sub-minute queries
- 80% lower ingest cost

The full four-phase decision framework this engagement applied lives in the matrix client materials, and the component-criteria page backs the architecture choices. For the named, public production architectures the framework draws on, the teardown catalog is the place.
