That might work for end user facing services but isn't the best fit for infrastructure. For infrastructure, you need something that people in the business understand well, are comfortable using, speaks the same language of operations so that vocabulary is well understood, and battle tested in production.

That's why Kubernetes has gained a lot of traction, not because 99% of companies need the scalability of Kubernetes, but it is a well understood concept, suite of services, and the vocabulary is very common now and well understood.

Nomad is a great fit for most compared to Kubernetes but failed to gain adoption because of these reasons.
