Many customer environments today have a mixture of OEMs and/or topologies that dictate a wider net be cast in the context of automation. While Cisco’s DNA Center provides some serious intelligence in the Assurance engine and really simplifies the deployment and management of a Campus Fabric it will not be able to cover the multiple OEMs. For non-fabric configurations it can use the Apache Velocity templating language but still that only would cover the Cisco topology and has some limitations related to idempotency and validating the configs remain in check with the "standard."

This is where joining the forces of Ansible and DNA Center can help drive a more comprehensive automation strategy resulting in a fully automated network with awesome visibility.
