Is your environment to small for an Exchange High-Availability?

Paul Cunningham wrote a very interesting article about that topic!
His key point here: No! possibly not.

And I agree a 100 percent!

What makes that so interesting: I had the same discussion with a customer last week!
They plan to move to the cloud (Office 365) soon. However, the customers business needs the mail service available. Now!

Here is my approach for the customer:

  • Install a second Exchange 2013 Server (virtual)
  • Establish a HAProxy based Load Balancer
  • Configure Database Availability Groups (DAG)
  • Configure a Witness-Server (Existing HA solution was used) – Could be a cheap Azure Service as well
