Few reasons : - Kubernetes is very complex to setup - It is not needed for many use cases - It is (hopefully) not the defacto and standard for devops - Load Balancing is already a solved problem way before Kubernetes. For many use cases, you don't need the complexity. Even things like Self Healing are kinda solved by AWS Auto Scaling for example. - NOt every use case needs Kubernetes and its additional overhead/complexity - Most importantly, devops is not "one size fits all" magic wand that Kubernetes or any other tool can solve. Various nuances to consider and hence you need DevOps as a role.
