Kubernetes is insurance for companies against getting locked in proprietary technologies.
It also promotes immutable infrastructure and hence increases the portability. While some of the things like load balancers and ingress are controlled by cloud provider almost everything else can be seamlessly migrated to another cloud provider or on prem.
It makes dev, test, staging, prod environments consistent and also solves a lot of pain points of managing infrastructre at scale with autoscaling, auto healing and more. Istio adds a lot more kubernetes and makes the supporting microservices even easier.
