No minimum, just in the process of slowly rolling this out over the next week or so. Stay tuned!

Cody Bratt, Google Cloud Console Product Manager

I have two GCE accounts - one personal, where I do have the cloud console feature, and one business domain currently on a $300 trial, where the button does not show up.

Curious

No button for my domain account as well. Have billing enabled. And when I attempt to send feedback on this issue, I get a "submission failed" error!

Have used micro instances in the past as remote development and deployment environments and a micro instance and it works ok. Wondering if something in between micro (0.7G) and standard (3.5G) might be better considering devenv can get pretty beefed up using certain modern frameworks we won't mention by name ;)

I don't have it on my main Google account, so I signed into a test account that I use pretty much for testing apps, but never for anything serious, and voila, there it is. So I'm guessing it's pretty random how it is being rolled out.
