Recently I was looking around in my virtual machine to find a topic to blog. Within a few minutes, I was having an idea. In this blog we would talk about an interesting feature “Pause SQL Server”. As stated via official Microsoft documentation “Pausing the Database Engine service prevents new users from connecting to the Database Engine, but users who are already connected can continue to work until their connections are broken.
