+   * @brief A class that provides strategies on deployment topology.
+   *
+   * This class provides strategies on how the DomainApplicationManager
+   * should deploy an deployment plan at domain-level.  This is achieved
+   * by providing mappings from deployment destination names to actually
+   * NodeManager daemon IORs, and the strategy for which default NodeManager
+   * daemons a deployment mechanism should use.
+   *
+   * This is a trivial implementation of the deployment configuration
+   * strategy.  We can enhance this class later on to provide
+   * different deployment location strategies, such as naming service.
