  Due to the limited and varying availability of cheap infrastructure and
resources, cloud network systems and applications are tested in simulation and
emulation environments prior to physical deployments, at different stages of
development. Configuration management tools manage deployments and migrations
across different cloud platforms, mitigating tedious system administration
efforts. However, currently a cloud networking simulation cannot be migrated as
an emulation, or vice versa, without rewriting and manually re-deploying the
simulated application. This paper presents SENDIM (Sendim is a northeastern
Portuguese town close to the Spanish border, where the rare Mirandese language
is spoken), a Simulation, Emulation, aNd Deployment Integration Middleware for
cloud networks. As an orchestration platform for incrementally building
Software-Defined Cloud Networks (SDCN), SENDIM manages the development and
deployment of algorithms and architectures the entire length from
visualization, simulation, emulation, to physical deployments. Hence, SENDIM
optimizes the evaluation of cloud networks.
