I am not sure so much that Kubernetes itself is an issue, as far as the technology. I'm personally a fan of serverless/lambda style functions, but my understanding is that many of those can run on Kubernetes under the hood. Same goes for heroku/digital ocean app services. Even elastic beanstalk. If you are large enough that you need to manage your own k8s cluster, that is one thing, but I would encourage you to look at your needs from a usage and compute perspective long before you start solutionizing with trendy technologies.
