Does Google Cloud have anything similar to the managed identity offered by Azure. Refer the video in below link:

As I understand Managed Identity eliminates the need for passwords and private keys. Services traditionally use a service account to access resources but that service account uses a password that needs to be stored in a secrets manager and periodically auto-rotated. Managed Identity eliminates need of any password.

An Azure System Assigned and User Assigned Identity is similar to a service account assigned to a Compute Engine instance. Neither method require passwords or secrets. Both methods store the authorization tokens in the metadata service.

Compute Engine: Service accounts

Google Cloud uses the service account identity (OIDC) extensively to authorize services to communicate with each other.

Azure Managed Identities. Like Google Service Account, Azure system assigned managed identity is used to authenticate resources like VM, Key Vault etc. using token/private keys.

  • The OP asked about a authentication system in GCP - they already seem familiar with Azure. So this does not seem to answer the question. – Bert Blommers Oct 23 '22 at 13:00
