Explanation

https://cloud.google.com/blog/products/it-ops/best-practices-for-optimizing-your-cloud-costs Schedule VMs to auto start and stop: The benefit of a platform like Compute Engine is that you only pay for the compute resources that you use. Production systems tend to run 24/7; however, VMs in development, test or personal environments tend to only be used during business hours, and turning them off can save you a lot of money! https://cloud.google.com/blog/products/storage-data-transfer/save-money-by-stopping-and- starting-compute-engine-instances-on-schedule Cloud Scheduler, GCP’s fully managed cron job scheduler, provides a straightforward solution for automatically stopping and starting VMs. By employing Cloud Scheduler with Cloud Pub/Sub to trigger Cloud Functions on schedule, you can stop and start groups of VMs identified with labels of your choice (created in Compute Engine). Here you can see an example schedule that stops all VMs labeled "dev" at 5pm and restarts them at 9am, while leaving VMs labeled "prod"
