As Organization Administrator, you must be notified of every change to objects in Cloud Storage with minimal management overhead. What should you do?

Configuring Cloud Storage object change notifications and forwarding them to Pub/Sub is the most efficient and scalable solution for real-time alerts with minimal management overhead. This method directly sends notifications about object changes (creation, deletion, updates) to a Pub/Sub topic, which can then trigger various downstream actions like email alerts or function executions. Inspecting Cloud Audit logs is reactive and requires manual or scripted polling, which is not real-time and has higher overhead. Enabling object versioning primarily helps with data recovery and doesn't inherently provide real-time notifications; combining it with Pub/Sub notifications for the bucket is a partial solution but less direct than using object change notifications. Enabling bucket versioning and running a custom script adds significant management overhead for script development, maintenance, and execution, making it less ideal for minimal overhead.
