Google Cloud hub
The root card of the Google Cloud hub — documentation that helps an AI coding agent make Google Cloud calls succeed, and compare Google Cloud against AWS and Azure for migration work. Ten families, each with references, an error catalogue, guides and a cross-cloud parity guide. Every fact cites a Google Cloud page read on 2026-10-21. It documents and never acts. Start at _boot/START.md.

This hub documents Google Cloud for an AI coding agent: how to fix a call that failed, how to write a call or a Terraform configuration that works the first time, and — the reason it was commissioned — how Google Cloud differs from AWS and Azure in the ways that change a migration estimate.
It documents and never acts. Nothing here runs a command, holds a credential, or changes anything in a project.

What this hub has that a service comparison table does not
A parity guide per family (guides/parity/<family>.md) and one method guide,
guides/parity-and-migration-method.md. The published cross-cloud tables map names; these map the
documented differences that change an estimate — naming, quota model, pricing dimension, regional model
and IAM model — plus the occasional difference that is a correctness risk rather than a cost.
Use it with cuppy's aws and azure hubs. The method guide says how.
The full index, with the identity each call should be made as:
reference/overview/services-and-identities.md.
The rules this hub is built on
- Every fact comes from a Google Cloud page fetched on 2026-10-21, cited in that document's
provenance with the URL, the read date and which fact it carries. Counterpart claims about AWS or Azure
cite an AWS or Microsoft page the same way.
- No adjustable quota and no price is ever typed here. The document names the call that reads the live
value. A number the vendor states as a fixed system limit is written down, with the page that calls it fixed.
- Absences are stated, not filled in. "The page does not say" appears a dozen times in this hub on
purpose. Guessing is the failure mode a documentation hub exists to prevent.
- Keyless, identity-based authentication first, everywhere. No real credential appears in any example.
- This hub assumes the global Google Cloud. Sovereign, air-gapped and Distributed Cloud deployments are
out of scope.
