After reading the SLA of Windows Azure Virtual Machines I was a little confused about the following statement:
For allInternet facing Virtual Machines that have two or more instances deployed in the same Availability Set, we guarantee you will have external connectivity at least 99.95% of the time.
What is an internet facing Virtual Machine? Let’s for example build the following solution mentioned in the “SharePoint 2013 on Windows Azure infrastructure services” documentation
That means two Virtual Machines deployed for each SharePoint Web, SharePoint App, DB and AD role. In my understanding only the Web and App role Virtual Machines are internet facing. The rest are back-end servers that are not exposed to the internet. So does this mean only my Web and App role servers of the SharePoint deployment get an SLA and the DB and AD won’t fall under a SLA even when I deploy two Virtual Machines in different update and fault domains?
Could someone from Microsoft please clarify this SLA statement to me?
