<p>What is the security model of AKS managed clusters ? Does AKS cluster of company A &amp; B share common resources like VM etc ? Please clarify. Thanks all.</p>

<p>security doesnt really stop at the RBAC (as the other answer mentions) level, you'd also need to consider network security (can be achieved with network policies, but you'd need Azure CNI in AKS for that), resource quotas, pod permissions, etc.</p>

<p>So there's a lot to consider here, with little gains. You could also use agent pools and create a separate pool for each company using AKS and instruct them to use specific node selectors for their stuff, but I dont think you can enforce it at all.</p>
