title: Azure AKS - splitting node pool over multiple Availability Zones
body: <p>I'm new to Azure so please bear with me! I'm looking to create a HA (99.99%) node pool for AKS. I am more familiar with AWS and availability zones, whereby I'd split the auto scaling group over 3 AZs and that would be that. </p>
  
  <p>It appears that Azure have picked up on AZs and do offer them (<a href="https://azure.microsoft.com/en-gb/blog/azure-availability-zones-now-available-for-the-most-comprehensive-resiliency-strategy/" rel="nofollow noreferrer">https://azure.microsoft.com/en-gb/blog/azure-availability-zones-now-available-for-the-most-comprehensive-resiliency-strategy/</a>) however, I don't see anyway to specify these parameters when creating an AKS cluster - <a href="https://docs.microsoft.com/en-us/cli/azure/aks?view=azure-cli-latest#az-aks-create" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/cli/azure/aks?view=azure-cli-latest#az-aks-create</a></p>
  
  <p>Am I missing something here? If I use the availability set, there is only a 99.95% availability target which doesn't fulfill what I need. Basically I want to architect so that if an AZ fails in Azure my app keeps running...</p>
  
  <p>Thanks!</p>
