Hello:
I currently have one SQL Server 2012 enterprise edition that the whole State Agency relies on. We have redundant web servers with load balancing and I am able to shut down one web server - update its code without our end users noticing (they automatically go to the other web server because our WAF senses that the server is down).. So I am looking for a similar solution for my databases, so that when I shutdown the database for maintenance (service packs - differential backup which locks tables, etc...) , the end users would not notice.
It seems like I need duplicate and redundant datastores.
There might be several approaches for that - what are your thoughts.
Thank you
