AWS on the other hand... A labyrinth of pricing tables, spot instances, EBS optimized, enhanced networking... Complexity.

I recently created a simple tool (http://theprice.cloud/) to compare egress traffic, object storage, and block storage cost among AWS, Google Cloud and Azure. It seems like Googel Cloud is the most expensive one in egress traffic and object storage.
Ingress Free
Egress inner-zone Free
Egress cross-zone in the same region $0.01
Egress cross-region within the US $0.01
Your site seems to be hugged to death (so I can't see it), but there are lots of gotchas with S3 pricing (like rounding up file sizes with Infrequent Access and Glacier) that in our experience means our customers come out ahead. Glacier and Coldline also aren't really comparable in the sense that GCS always responds within milliseconds. We only economics to discourage frequent access from Coldline, not delays. As above, our egress is more expensive because it's better (we hear you though if your response is "I don't care! Give me cheaper instead, then!").

Having Diane Green in charge of GCP is an indication that developing GCP as a business is a high priority.
I've also fixed a few minor things that annoyed me, such as correct sorting by instance type (so that r3.16x goes after r3.4x) and added a mode to display spot savings vs on-demand.
Would appreciate any feedback!
For me, it would also be nice to see the total price/time unit on the same table as the price/gb.
