> what can k8s do to AWS SaaSes (e.g. RDS, SNS, etc...)?

k8s has allowed us to not use RDS any more because we now host PostgreSQL inside k8s instead. It's a bit more overhead, but we're now portable and run in gcp too with the same k8s manifests and almost no porting effort.

So yeah, we escaped the lock-in.

And now we're not just tied to the AWS stuff and we're experimenting with cockroachdb and other products that aren't there "natively" in AWS, so beyond escaping lock-in, we're more ready to experiment with newer stuff.
