## Summary

Databricks publishes a four-stage guide to scaling Databricks Apps: design, build, test and deploy, and operate. It recommends setting latency and peak-load targets first, keeping session state rebuildable, and using load tests to choose instance size and count. The guide also estimates Lakebase connections as instances × workers × pool size, and notes the default limit is five instances per app.
