[Notes from Pinal]: The basic nature of human is greedy. When we get one thing which we desire the next thing. In the early world of SQL Server we got a secondary server as a backup or high availability. In earlier times the secondary server was not readable, it just served as a backup. At this point of time our human nature kicked in and we want to get more from the server, which was just sitting there most of the time. We wanted to make our secondary server readable. This is when I reached out to Kenneth and asked him what can we do to make our secondary server as a readable.
