As long as your k8s is some self contained island of code needing no R/W access to resources on k8s, maybe I'll believe it's easy to setup AND to support. Additionally if you are in some type of small shop environment where you have basically unfettered permissions in AWS console to do what you need, doubly so.
Now try to get access to/from RDS, S3, EFS, Netapp NFS, some HTTP endpoint on-prem, some other HTTP endpoint on EC2, non-MSK Kafka, cross account, etc? Pain.
Oh you need to submit a ticket to your Linux sysadmins, Infra team, CloudOps, DevOps, Networking or Infosec for each of the above permissions? And sometimes need 2-3 of those teams to coordinate to make it happen? Death.
