Having a single central storage is alright if your use case requires so. Additionally, if you use Google Cloud Storage for that end, you won’t have to worry about replication, backups, encryption, etc.

How to do it:

There gotta be more than one way to achieve it. I can recommend you the following:

  1. Create one or more storage buckets in one of your projects, let’s call it project A. Note that bucket names are global identifiers, so you can reference your bucket from within different projects using the same name.

  2. In your other projects, take note of your Compute Engine Instances Service Accounts. A Service account is the identity that an instance uses to authenticate and gain access to other GCP services. If you didn’t define a custom Service Account for your instances, then they are set up to use the default Compute Engine Service Account. More on this here.

  3. Back to project A, go to IAM & admin and add your other project’s service accounts as members and grant them the Storage related role you require, for example, Object Admin.

  4. Now you can access your bucket in Project A from your instances in other projects using gsutil command line tool or the Cloud Storage API.
