Google Cloud IAM

Identity and Access Management (IAM) lets you authorize who can take action on specific resources, giving you full control and visibility to manage cloud resources centrally.

Key Features

  • Fine-grained control: Grant only the necessary permissions.
  • Single Interface: Unified access control across all Google Cloud services.
  • Context-aware: Control access based on attributes like IP, device, and time.

Use Cases

  • User Management: Grant access to team members.
  • Service Accounts: Grant access to applications and VMs.

Key Concepts

  • Principal: Who is requesting access (User, Service Account, Group).
  • Role: A collection of permissions (Viewer, Editor, Owner, Custom).
  • Policy: Binds principals to roles on a resource.
