Fixing Databricks BOOTSTRAP_TIMEOUT with AWS PrivateLink, No New Subnets
A developer resolves Databricks cluster bootstrap timeouts by routing control-plane traffic through AWS PrivateLink instead of the public internet. The fix uses two VPC endpoints for Databricks' REST API and SCC relay, requiring zero new subnets or routing changes. This approach eliminates reliance on firewall allow-lists and keeps traffic off the public internet.
Meridian48 take
