Moving from classic servers to containers you get:

- Builds with fixed dependencies that never change. Rollback is easy -> what about VMs?

- Easy deployment of a prod environment on a local machine -> yep, that's a nice touch, the only valid point for me!

- Fast deployment -> lol no, Im faster with VMs.

- Easy automation (use version X with config Y) -> valid for VMs and baremetal too

With Kubernetes (or other derivates like Openshift) you get:

- Auto scaling -> you can get it with VMs too

- Fail over -> you can get it with VMs too

- Better resource usage if multiple environments are executed -> you can get it with VMs too

- Abstraction of infrastructure -> Should I really write it?

- Zero downtime deployment (biggest point for my company, we deploy >3 times per week) -> We do on some specific DC (government style) and we release 10-15 times and day with Bare metal servers and ansible

There are applications that do not need Kubernetes or even containers, but is this list really nothing oO? -> None of the arguments convinced me

I can imagine that if you use Kubernetes just like a classic cluster it could seem like an unnecesarry added complexity but you gain a lot of things. -> yes, extra cost and extra skills needed
