These examples were created by GCP for the GCPNext 2016 event. There were used to start discussions for user needs. Experts in the specific verticals were consulted in developing the diagrams, but they are not recommended or validated designs--not detailed enough. The diagrams are intended to spark discussions, and so you don't have to start from scratch.
I did several of them, most come from the GCP Solutions Architecture team. AMA!
We are very much looking forward to using them in ours, too!
Would an ad server/logging solution make sense to add? Apart from Amazon's solution I had a real struggle finding something concrete.
