If you use DevOps processes, automation and orchestration are king — which is why the Google Cloud cron service can be a great tool for managing your Google Compute Engine instances via Google App Engine code. This kind of automation can often involve multiple Google Cloud services, which is great for learning about them or running scheduled tasks that might need to touch multiple instances. Here are a few ideas on how to use the Google Cloud cron service:

1. Automated Snapshots

Since Google Compute Engine lets you take incremental snapshots of the attached disks, you can use the Google App Engine cron to take these snapshots on a daily or weekly basis. This lets you go back in time on any of your compute instances if you mess something up or have some systems fail. If you use Google’s Pub/Sub service, you can have the snapshots take place on all instances that are subscribed to that topic.

As a bonus, you can use a similar idea to manage old snapshots and deleting things you don’t need anymore. For example, schedule a Google Cloud cron to clean up snapshots three months after a server is decommissioned, or to migrate those snapshots to long-term storage.

2. Autoscaling a Kubernetes Cluster

With Google on the forefront of Kubernetes development, many GCP users make heavy use of GKE, the managed Kubernetes service. In order to save some money and make sure your containers aren’t running when they aren’t needed, you could set up a cron job to run at 5:00 p.m. each weekday to scale down your Kubernetes cluster to a size of 0. For maximum cost savings, you can just leave it off until you need it, then manually spin up the cluster, or you could use a second cron to spin you clusters up at 8:00 a.m. so it’s ready for the day.
