Topic Availability Groups: What They’re Not Telling You
Date Thursday, May 18, 2017 from 5:00 PM to 6:00 PM (AWST)

Nicholas Cain


SQL Server 2012 brought to life a new form of high availability and disaster recovery in the form of Availability Groups (AGs). This all sounds fantastic, but in reality there are issues and problems that are generally not discussed, or well known, that can impact your HA/DR story and cause major performance issues. In this session, I’ll give a brief overview on AGs in SQL Server 2012 and the enhancements that come in 2014 and 2016. Then we’ll get into some of the problems that exist, that I’ve seen in the real world of using AGs, and that you should be aware of before implementing it in your environment.

(This is a tour de force of real-world technical issues with AGs seen in 5x9 architectures and this information isn't readily available anywhere else! Highly recommended if you're ever going to use AGs seriously! - CK)
