I'm still new to GCP - but I've found the tutorials helpful.

The Manning book "Google Cloud Platform In Action" has been somewhat helpful in providing additional examples above what I've seen in the official docs - it's a MEAP so still being written. https://www.manning.com/books/google-cloud-platform-in-actio...

The "Google Cloud" YouTube channel has some videos I've found interesting : https://www.youtube.com/user/googlecloudplatform
