<p>I'm using a GKE. For single zone it is free of charge(only instance cost). For DEV we are using it but for another environment like QA/DEV/Production do we need separate GKE Cluster or inside the current GKE a different namespace will work ? which is the best way in cost and security</p>

<p>This depends on your requirements. Both options are viable.</p>

<p>In a professional environment for a large enterprise, this would be different clusters in different <a href="https://cloud.google.com/vpc" rel="nofollow noreferrer">VPC</a> (one <a href="https://cloud.google.com/vpc" rel="nofollow noreferrer">VPC</a> per environment) and you might use separate projects as well, but not needed.</p>

<p>this is cheaper, but you have less separation. Only you know what you need.</p>
