title: AWS & Azure Hybrid Cloud Setup - is this configuration at all possible (Azure Load Balancer -> AWS VM)?
body: <p>We have all of our cloud assets currently inside Azure, which includes a Service Fabric Cluster containing many applications and services which communicate with Azure VM's through Azure Load Balancers.  The VM's have both public and private IP's, and the Load Balancers' frontend IP configurations point to the private IP's of the VM's.</p>
  
  <p><strong>What I need to do is move my VM's to AWS</strong>.  Service Fabric <strong>has</strong> to stay put on Azure though. I don't know if this is possible or not.  The Service Fabric services communicate with the Azure VM's through the Load Balancers using the VM's <em>private</em> IP addresses.  So the only way I could see achieving this is either:</p>
  
  <ol>
  <li>Keep the load balancers in Azure and direct the traffic from them to AWS VM's.</li>
  <li>Point Azure Service Fabric to AWS load balancers.</li>
  </ol>
  
  <p>I don't know if either of the above are technologically possible.  </p>
  
  <p>For #1, if I used Azure's load balancing, I believe the load balancer front-end IP config would have to use the public IP of the AWS VM, right?  Is that not less secure?  If I set it up to go through a VPN (if even possible) is that as secure as using internal private ip's as in the current load balancer config?</p>
  
  <p>For #2, again, not sure if this is technologically achievable - can we even have Service Fabric Services "talk" to AWS load balancers? If so, what is the most secure way to achieve this?</p>
  
  <p>I'm not new to the cloud engineering game, but very new to the idea of using two cloud services as a hybrid solution.  Any thoughts would be appreciated.</p>
