// 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.
