To me, DevOps is quickly configuring a Google Compute Engine instance with Python/Go app using (PubSub or RabbitMQ) to communicate Firebase for iOS application messages, with a DigitalOcean.com and AWS instances. DigitalOcean will often be used for Postfix Email, which requires DNS (SPF configuration and filtering). These are usually quick configurations outside the main development, to quickly test a new concept, or maybe to troubleshoot an issue. You're using Python Pandas, TensorFlow, scikit-learn.org to model/prove verify the issue. I would say the traditional DevOps (if there was one), has expanded... you've added System Admin, DBA, Developer and a Machine Learning to your toolkit. Of course, we all have smartphones, so we leverage that too...
