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
