SQL Server is used by business applications, web applications, individual programmers, and for content-intensive websites. Microsoft SQL is popular among the developers because it is a powerful, expandable, and upgradeable choice for database solutions. Microsoft SQL Server 2012 is equipped with various features. Many server makers have built products based on this platform, such as the Dell SQL server. We will be discussing the AlwaysOn feature of SQL Server 2012 in this article.
