• Reacting to events from Pub/Sub, Cloud Storage, Firestore, or Eventarc
• Running scheduled tasks (cron) without maintaining a server
• Building data-processing pipelines triggered by file uploads
• Prototyping microservices before committing to Cloud Run or GKE

Prerequisites

• Google Cloud SDK (gcloud) installed and authenticated
• APIs enabled: Cloud Functions, Cloud Build, Artifact Registry, Cloud Run (Gen2)
• IAM role roles/cloudfunctions.developer (or roles/run.developer for Gen2)
