Kubernetes is the standard for infrastructure, everyone should use it instead of VM or all others singular infrastructure. All others options are costly on the mid and long term.
Kibernetes brings me overhead and wastes system resources.
I already have infrastructure as code.
Why would I want to containerize systems I already have YAML to describe?
People forget they real hardware has to run this stuff, and layers os schedulers are not helpful.
Look at the disaster of fibers threads and processes already!
