Created a kubernetes cluster with private topology on aws using kops

My application exposes several services. As expected, services communicate among each other using their names, i.e. the name field below:

kind: Service
metadata:
  name: myservice
  namespace: staging_namespace

Here is the question:

Assuming that I will deploy 2 version of my application (e.g. testing and staging) in different namespaces, will this prevent service name collision?

Will namespace separation allow

• service1 reach the correct myservice in staging_namespace in my staging deployment

• service1 reach the correct myservice in testing_namespace in my testing deployment

?

Using

kops version
Version 1.8.0 (git-5099bc5)

and

$ kubectl version
