We're conducting a survey with the community to learn more about how you build Cloud Native applications, what you enjoy about it and the challenges that you're facing. We'll be sharing the results publicly once the survey closes.
Is there a way to do cloud native without using kubernetes?
Yeah, you can use other container orchestrators and still build cloud native apps. Although in practice, almost everyone uses Kubernetes.
why would you want to introduce legacy from the get go?
I don't think you should. But some organizations have legacy needs and might be using other orchestrators. Or K8s might not be a good fit for them for whatever reason.
