What is App Hub?
App Hub is the application-centric management and registry layer of Google Cloud. The service abstracts individual infrastructure resources from one or more projects into standardized logical constructs: services and workloads are grouped into applications, each mapping to a concrete business function. This creates a unified view that makes resource ownership, dependencies and business context visible.
In large cloud environments, resources are often spread across many projects and teams, which makes them hard to track. App Hub solves this by discovering existing, already deployed resources within a management boundary and mapping them to logical applications. Management runs through a central management project whose boundary can be set at the folder or project level.
Core Capabilities
- Application registry: App Hub serves as a single source of truth for applications and groups distributed resources into logical units across project boundaries.
- Discovery-based registration: Already deployed services and workloads within the management boundary are discovered and can be mapped to applications.
- Global and regional applications: Applications can be defined as global or regional, supporting data residency and compliance requirements.
- Integration with the Google Cloud ecosystem: App Hub provides the data model for Cloud Hub, Google Cloud Observability and Gemini Cloud Assist.
Typical Use Cases
Unified application view: In multi-project architectures, App Hub bundles related resources into a single application and creates a consolidated overview without manual inventory work.
Clear ownership: By mapping services and workloads to applications, ownership and dependencies become transparent, which simplifies operations and handovers between teams.
Foundation for operations and monitoring: App Hub’s standardized data model enables application-centric monitoring through Cloud Hub and supports troubleshooting with Gemini Cloud Assist.

Frequently Asked Questions
What is App Hub?
App Hub is Google Cloud's central application registry. It groups distributed resources from one or more projects into logical applications, services and workloads. The result is a unified view of your applications with clearly defined ownership, dependencies and business context.
When should I use App Hub?
App Hub fits when infrastructure is spread across many projects and teams and visibility into related resources is missing. Typical scenarios include multi-project architectures, application-centric monitoring, and a unified data model as the basis for Cloud Hub and Gemini Cloud Assist.
How much does App Hub cost?
The App Hub APIs are offered free of charge to all customers. There are no fees for using App Hub itself. As usual, costs only arise for the underlying cloud resources that you operate and register.
Is App Hub available in the EU?
Yes. App Hub is available in multiple regions, including regions in Europe. Applications can be defined as global or regional. The location choice affects which resources can be registered and has implications for data residency and compliance.
