In my previous post(https://itsolutionsdirect.com/designing-vm-deployments-by-leveraging-availability-sets-fault-domains-and-update-domains-in-azure/904/) we discussed the theory behind Azure Availability Sets and how to implement them.  Whilst Azure Availability Set’s protect you from host maintenance/failure within the datacentre, they do not protect you from a complete datacentre failure.  This is where Azure Availability Zones come into play.  When you deploy an VM’s into an …

When designing and building an Azure infrastructure you still need to think about high availability to ensure uptime when host servers are rebooted due to unplanned (i.e. power outages) and planned maintenance (i.e. monthly patching).  In a tradition on-premise Datacentre we achieved this by using clusters, load balancers and active-active services deployed across multiple DC’s.  …
