///
/// Cloud Spanner Instance Admin API
///
/// The Cloud Spanner Instance Admin API can be used to create, delete,
/// modify and list instances. Instances are dedicated Cloud Spanner serving
/// and storage resources to be used by Cloud Spanner databases.
///
/// Each instance has a "configuration", which dictates where the
/// serving resources for the Cloud Spanner instance are located (e.g.,
/// US-central, Europe). Configurations are created by Google based on
/// resource availability.
///
/// Cloud Spanner billing is based on the instances that exist and their
/// sizes. After an instance exists, there are no additional
/// per-database or per-operation charges for use of the instance
/// (though there may be additional network bandwidth charges).
/// Instances offer isolation: problems with databases in one instance
/// will not affect other instances. However, within an instance
/// databases can affect each other. For example, if one database in an
/// instance receives a lot of requests and consumes most of the
/// instance resources, fewer resources are available for other
/// databases in that instance, and their performance may suffer.
///
/// @par Equality
///
/// Instances of this class created via copy-construction or copy-assignment
/// always compare equal. Instances created with equal
/// `std::shared_ptr<*Connection>` objects compare equal. Objects that compare
/// equal share the same underlying resources.
///
/// @par Performance
///
/// Creating a new instance of this class is a relatively expensive operation,
/// new objects establish new connections to the service. In contrast,
/// copy-construction, move-construction, and the corresponding assignment
/// operations are relatively efficient as the copies share all underlying
/// resources.
///
/// @par Thread Safety
///
/// Concurrent access to different instances of this class, even if they compare
/// equal, is guaranteed to work. Two or more threads operating on the same
/// instance of this class is not guaranteed to work. Since copy-construction
/// and move-construction is a relatively efficient operation, consider using
/// such a copy when using this class from multiple threads.
///
