App Hub 充当 Google Cloud上应用的基础数据模型和中央注册表。它创建了一个可信来源，用于明确资源所有权、依赖关系和业务背景信息。这反过来又为其他 Google Cloud 服务提供了所需的以应用为中心的上下文。如需详细了解这种以应用为中心的模型及其资源组织方式，请参阅以应用为中心的 Google Cloud。
为了启用以应用为中心的功能，App Hub 使用基于以下 Google Cloud 文件夹和项目的模型：
推荐： 已启用应用的文件夹：已针对应用管理配置的标准 Google Cloud 文件夹。此文件夹充当应用的管理边界。当文件夹启用应用后，系统会在其中 Google Cloud 自动创建管理项目。此 Google 创建的项目可作为所有应用模型和元数据的中央存储库。这是使用以应用为中心的 Google Cloud 产品的推荐途径，也是访问全套应用管理功能的必要条件。
宿主项目：一种 Google Cloud 项目，您可以使用它在 App Hub 中将服务和工作负载分组为应用，但它不支持访问应用管理功能的完整产品。

This approach can make your resources difficult to\nmanage and organize. App Hub provides an application-centric way to\ngroup these resources, helping you align your infrastructure with your business\nfunctions.\n\nApp Hub acts as the foundational data model and central registry for\nyour applications on Google Cloud. It creates a single source of truth that\nclarifies resource ownership, dependencies, and business context. This, in turn,\nsupports other Google Cloud services with the application-centric context they\nneed. For more information about this application-centric model and its resource\norganization, see [Application-centric Google Cloud](/app-hub/docs/application-centric-google-cloud).\n\nThis document provides a conceptual overview of App Hub to help you\nunderstand its features and benefits before you set up or administer it.\n\nWhy use App Hub?\n----------------\n\nBy shifting the focus from individual infrastructure components to the\napplications they form, App Hub helps you streamline governance and\noperations at scale.\n\nApp Hub helps you implement the following:\n\n- **Organize and catalog your applications** : Group scattered resources from\n one or more projects into logical applications. You can then categorize\n these applications with attributes like owners, business criticality, and\n environment to improve discoverability and accountability. For more\n information, see [Support discoverability and governance](#properties-and-attributes).\n\n- **Create a unified view for your teams**: By defining an application in\n App Hub, you provide essential context to other Google Cloud\n services. For example, you enable the following capabilities:\n\n - **Central view of operations and insights** in [Cloud Hub](/hub/docs/app-project-views), which displays alerts, incidents, and performance data in an application context.\n - **AI-powered assistance** from [Gemini Cloud Assist](/gemini/docs/cloud-assist/overview), which uses App Hub's data model to help you design, operate, and troubleshoot your applications.\n - **Application monitoring** with [Google Cloud Observability](/stackdriver/docs/observability/about-application-monitoring) to help you troubleshoot errors and improve performance by displaying telemetry data for your applications and their resources.\n- **Clarify resource ownership and dependencies**: Understand how your\n applications are composed and how their components depend on each other.\n This feature helps developers and operators visualize application\n architecture, identify owners, and resolve issues.\n\nTo learn more about how App Hub fits into the broader application\nlifecycle, see [Application-centric Google Cloud](/app-hub/docs/application-centric-google-cloud).\n\nConcepts and data model\n-----------------------\n\nApp Hub is built on a data model based on the following key concepts:\napplications, services, and workloads. While these terms are common,\nApp Hub uses them in a specific way. The following table compares the\nApp Hub definition with common industry usage:\n\nFor more information about these central concepts, see\n[Key concepts](/app-hub/docs/application-centric-google-cloud#app-centric-concepts).\n\nYou can scope App Hub applications based on your geographic\ndistribution requirements. You can designate the following scopes:\n\n- *Global* applications can group services and workloads from multiple Google Cloud regions.\n- *Regional* applications contain resources that all reside within a single region.\n\nThis choice impacts which resources you can register and can be important for\ndata residency requirements. For a detailed comparison to help you choose the\nright scope, see\n[Global and regional applications](/app-hub/docs/global-regional-applications).\n\n### Support discoverability and governance\n\nTo enrich the data model, App Hub lets you expose *properties* and\n*attributes* to support application discoverability, accountability, and\nresource governance. Defining these values as application metadata helps you\nfilter, manage, and apply policies to your resources at scale.\n\nThe following are the definitions and features of properties and attributes:\n\n- **Properties** are immutable fields that describe the underlying\n infrastructure of a registered service or workload, such as its project ID,\n location, or zone. These are discovered automatically and cannot be edited\n in App Hub.\n\n- **Attributes** are mutable, user-defined metadata that you can apply to\n applications, services, and workloads to organize and govern them. Key\n attributes include:\n\n - **Owners:** Contact information for developer, operator, and business\n teams. The supported owner types are:\n\n - `developer_owners`: Development team that owns development and coding.\n - `operator_owners`: Operator team that ensures runtime and operations integrity.\n - `business_owners`: Business team that ensures quality and user expectations are met.\n - **Criticality:** The importance of the resource to your business. The\n supported values are:\n\n - Mission critical\n - High\n - Medium\n - Low\n - **Environment:** The lifecycle stage of the resource. The supported\n values are:\n\n - Production\n - Staging\n - Test\n - Development\n\nThe App Hub resource model\n--------------------------\n\nTo enable application-centric features, App Hub uses a model based on\nthe following Google Cloud folders and projects:\n\n- Recommended: **App-enabled folder** :\n A standard Google Cloud folder configured for application management. This\n folder acts as an administrative boundary for your applications. When a\n folder is app-enabled, Google Cloud automatically creates a\n *management project* within it. This Google-created project acts as a\n central repository for all your application models and metadata. This is the\n recommended path for using Application-centric Google Cloud products and is required to access the\n full offering of application management features.\n\n- **Host project**: A Google Cloud project that you can use to group services\n and workloads as applications in App Hub, but that doesn't support\n access to the full offering of application management features.\n\nFor more information about the application-centric resource model, see\n[Resource organization concepts](/app-hub/docs/application-centric-google-cloud#resource-organization-concepts).\nFor detailed instructions on getting started, see\n[Choose your setup model](/app-hub/docs/set-up-app-hub).\n\nWhat's next\n-----------\n\n- To see which Google Cloud resources you can register in App Hub, see [Supported resources](/app-hub/docs/supported-resources).\n- To get started with setting up App Hub, see [Set up App Hub with app-enabled folders](/app-hub/docs/set-up-app-hub-folder).\n- To understand the permissions required to use App Hub, see [Roles and permissions](/app-hub/docs/roles-permissions)."]]
