We have ansible playbooks that we wrote leveraging some of the ansible-galaxy stuff, and they do the same thing either on-prems or in cloud. I would say we're pretty cloud native, we follow best practices and deploying something to a cloud provider or internally is the same thing.

Our level of abstraction is containers, we don't use services that cloud providers sell, for example, Lambda, as they are very cloud provider specific. We prefer to use technologies like RabbitMQ which can be deployed on any cloud or on prems easily.
