The Istio project is not supposed to be tied to Kubernetes. It is supposed to be a general-purpose service mesh.
That being said, I have been looking for a while and I can't find anyone who uses it in production on a platform other than Kubernetes.

(There are also obvious technical reasons for decoupling something like this from Kubernetes, mostly the opinionated nature of forcing a service mesh over other potential solutions).
