This isn't a good example. Switching languages does not make this simpler. Switching the _implementation_ of an interface does. For example, I could implement a "queue" interface three times - once for Confluent Cloud's Kafka, once for Kinesis and once for EC2 instances that run OSS Kafka. The interface remains stable, the implementation changes. This can also be done across clouds. I think it's worth you doing some more research into what Pulumi opens up before using it as an example like this in marketing material.
