Hey Demian,
There are many meteor tutorials out there, even some good ones linked from the official website, so you should follow those as far as meteor goes, but as far as deploying to the Cloud Platform, you should look into either
App Engine Custom Runtimes or
Compute Engine (and Compute Engine's
HTTP(S) Load Balancer). Both will allow you to create a VM running a meteor server process.
Let me know if you have any further questions, I'll be glad to assist.
Cheers,
Nick
