A CI job publishes a new predictive-model release every Tuesday. The security Cloud Function should run immediately after each release on that weekly cadence. How do you wire the trigger?

The correct approach is to configure the deployment job to publish a message to a Pub/Sub topic, which then triggers the Cloud Function. This creates a direct, event-driven workflow where the function executes immediately upon the new model release. Pub/Sub is designed for asynchronous messaging and event ingestion, making it ideal for decoupling the deployment process from the security function's execution. Cloud Tasks is for scheduling or queueing tasks, not directly for immediate, event-driven triggers from a CI job. Cloud Logging sinks are for exporting logs, not for initiating actions based on a deployment event. IAM and Confidential Computing are security and compute isolation features, not mechanisms for triggering functions based on deployment events.
