/**
 * 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.
