<p>How to configure routing between Pods on multiple Azure Kubernetes clusters?</p>

<p>Something similar to <code>ip-alias/vpc-native</code> on Google Cloud</p>

<p>In AKS, I think you can create the AKS clusters in the different subnets in the same vnet with an advanced network. For more details about the network, see <a href="https://learn.microsoft.com/en-us/azure/aks/operator-best-practices-network" rel="nofollow noreferrer">Choose the appropriate network model</a>. But it's not a perfect solution and there are some limitations for it. For example, the AKS clusters should be in the same region as the vnet.</p>

<p>You can take a look at <a href="https://www.cockroachlabs.com/blog/experience-report-running-across-multiple-kubernetes-clusters/" rel="nofollow noreferrer">Gotchas &amp; Solutions Running a Distributed System Across Kubernetes Clusters</a>. As it said, it's hard to communicate from different regions and nothing has yet solved the problem of running a distributed system that spans multiple clusters. It’s still a very hard experience that isn’t really documented.</p>

<p>So, maybe there would be a long time to wait for the perfect solution.</p>
