It is the\ntenancy unit that every service needs to integrate. It provides logical grouping\nof service instances.\n\nProjects enable segmentation of resources within an organization and provide a\nlifecycle and policy boundary for managing resources. Resources inside a project\ncan never outlive the project itself or move between projects, ensuring that\ncontrol is guaranteed for the life of the resource.\n\nA project is considered a proper Kubernetes namespace that spans across multiple\nKubernetes clusters in an organization. Kubernetes treats each cluster as a separate\nentity, and each cluster has an independent project namespace. However, for all\nclusters in a GDC organization, GDC\nconsiders all namespaces of a given name the same namespace. This is\nreferred to as namespace sameness. The single namespace has a consistent owner\nacross the set of clusters. Service providers create project-scoped services by\ncreating control plane and data plane components in the namespace.\n\nThe namespace for the project, called the *Project Admin Namespace*, hosts the\nfollowing:\n\n- Project-scoped service APIs, or Kubernetes custom resource definitions.\n- Project-level policy configurations, such as roles and role bindings.\n\nYou can configure a project to span across only a subset of Kubernetes clusters in an\norganization. Users can deploy containerized workloads on these clusters within\nthe project namespace. The namespace sameness concept applies to the project\nnamespace on these clusters. Namespace-scoped policies, such as role-based\naccess (RBAC) policies, apply to all those namespaces.\n\nFor more information on the resource hierarchy of GDC\nand best practices for organizing your resource hierarchy, see the\n[Resource hierarchy and access control](/distributed-cloud/hosted/docs/latest/gdch/resources/resource-hierarchy)\nguide."]]
