How to Run an Ethereum Node in GCP

NOTE: This doc was created in 2018 and is no longer being kept up-to-date. There are some useful updates and Q&A in the comments, and Google has since disallowed cryptocurrency nodes explicitly in their Terms of Service. While I work on an updated how-to-run-a-node tutorial, you are welcome to join our ETH developer chat and share what you'd like to work on.
