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?
you can use virtual network peering and\or site-2-site VPN.
Networks address space have to not overlap
