<p>I have 2 kubernetes clusters in Azure. Let's call them LegacyCluster and NewCluster. NewCluster is provisioned with Terraform.
Each has LegacyService and NewService. I need NewService to securely call LegacyService over rest. How can I do this? Is there a feature in either Kubernetes or Azure to make two networks act like one?</p>

<p>you can use <a href="https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview" rel="nofollow noreferrer">virtual network peering</a> and\or <a href="https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpngateways" rel="nofollow noreferrer">site-2-site VPN</a>.</p>

<p>Networks address space have to not overlap</p>
