Playing with data is a joy in Junyper/Datalab, but I do not want it to become costly.
"You can minimize compute charges by stopping/restarting Cloud Datalab instances."
However, if I stop the AppEngine instance or the Compute Engine VM instance, they simply restart ...
So how to correctly stop/pause Google Cloud Datalab, so that I'm only charged for my use, not for the idle time? Is there some kind of trigger that restarts the instances?
Here's what I'm doing. I like keeping everything in the cloud; but, I want to resume work with minimal fuss and cost.
Save Data/Source and Delete Datalab
1. Commit changes to Your Cloud Git Repository. As long as the source changes are committed, they'll pop backup when you re-create google cloud. Keep your data in buckets gs://... or BigQuery. Commit all changed Notebooks.
2. Delete the datalab module.

Resuming Your Work:
When you're ready to resume your work, goto launch cloud datalab sign-in, and deploy. It will take 6 or 7 minutes. Once it's deployed, up, and running, you can go directly to your tree and resume your work. You're probably talking 10 minutes tops.
