// instances:
// * The service works with a collection of cloud projects, named: `/projects/*`

// * Each location has a collection of Redis instances, named: `/instances/*`
// * As such, Redis instances are resources of the form:

// Note that location_id must be referring to a GCP `region`; for example:
// * `projects/redpepper-1290/locations/us-central1/instances/my-redis`
