Availability Groups - My Bookmarks

  • Article

 

I pondered a lot of time, what should I blog about?

Eventually I came up with this idea of aggregating all the links that I have collected/read about  AlwaysOn Availability Groups.

Why Availability Groups?- It is the hottest topic in SQL Server 2012.

Since it is a new topic, Many database administrators and system administrators will have a lot of questions and hence will search the web for information. So I thought, why not aggregate the information and put it in one place.

 

I will try to keep the list as updated as possible.

So Here is the List.
