1. Components


  • All data in Cloud Storage belongs inside a project. 
  • A project consists of a set of users, a set of APIs, and billing, authentication, and monitoring settings for those APIs. 
  • Users can have access to one project or multiple projects.


  • Cloud Storage uses a flat namespace to store objects. 
  • Google Cloud Console and gsutil can work with objects as if they are stored in a virtual hierarchy, as a convenience.


  • A resource is an entity within Google Cloud. 
  • Each project, bucket, and object in Google Cloud is a resource.
  • Each resource has a unique name that identifies it, much like a filename. 


  • There is only one Cloud Storage namespace.
  • Every bucket must have a unique name across the entire Cloud Storage namespace. 
  • Object names must be unique only within a given bucket.
