Yes, this is definitely possible.
If you are an Amazon S3 user, you can easily migrate your applications that use Amazon S3 to use Cloud Storage. You have two migration options:
-
Simple Migration: This is the easiest way to get started with Cloud Storage if you are coming from Amazon S3 because it requires just a few simple changes to the tools and libraries you currently use with Amazon S3.
-
Full Migration: A full migration from Amazon S3 to Cloud Storage requires a few extra steps compared to a simple migration, but the benefit is that you can use all the features of Cloud Storage, including support for service accounts, multiple projects, and OAuth 2.0 for authentication.
