The existing 30-year-old networking model is failing to keep up with the automated service architectures and the Internet of Things (IoT) based on end-to-end automation.
    - **To facilitate the migration to cloud-era computing, service providers and data centers must add networking into the automated service workflows.** This requires agility and elasticity that traditional networking products are not designed to provide. As IT environments of tomorrow involve a plethora of orchestrators and controllers spinning up services and applications inside shared networks, they all must be managed and provisioned by a unified solution authoritative for all network-related information.
