To use Cloud Bigtable, you create instances, which contain clusters that your applications can connect to. Each cluster contains nodes, the compute units that manage your data and perform maintenance tasks. A Cloud Bigtable instance is identified by its project_id and instance_id.

\nThis class identifies a Cloud Bigtable Instance. \nTo use Cloud Bigtable, you create instances, which contain clusters that your applications can connect to. Each cluster contains nodes, the compute units that manage your data and perform maintenance tasks. A Cloud Bigtable instance is identified by its `project_id` and `instance_id`.\n| **Note:** This class makes no effort to validate the components of the instance name. It is the application's responsibility to provide valid project, and instance ids. Passing invalid values will not be checked until the instance name is used in an RPC to Bigtable.\n\n###### See Also\n\n\u003chttps://cloud.google.com/bigtable/docs/instances-clusters-nodes\u003e for an overview of Cloud Bigtable instances, clusters, and nodes.\n\nConstructors\n------------\n\n### InstanceResource(Project, std::string)\n\nConstructs an [InstanceResource](/cpp/docs/reference/bigtable/2.13.0/classgoogle_1_1cloud_1_1bigtable_1_1InstanceResource) object identified by the given `project` and `instance_id`.\n\nFunctions\n---------\n\n### project() const\n\nReturns the [`Project`](https://cloud.google.com/cpp/docs/reference/common/latest/classgoogle_1_1cloud_1_1Project.html) containing this instance.\n\n### project_id() const\n\n### instance_id() const\n\nReturns the Instance ID.\n\n### FullName() const\n\nReturns the fully qualified instance name as a string of the form: \"projects/"]]
