Microsoft SQL Server 2016 is coming to Linux will provide the ability for users to have the features and additional security.
Microsoft will be releasing a version of their SQL Server 2016 for Linux which is a major step in the world domination plan. With about 35 percent of the web servers in the world using Linux as their operating system this will open new revenue streams for Microsoft.
As you can see from the grid below the percentages of SQL Servers within companies. The area where MySQL rules is on the web server which puts both at about 35 percent each on market share. If Microsoft begins the move towards Linux the development tools will be released shortly. What this means for a small company using a web server, they now have an option to use the Linux OS but with a robust SQL Server that also contains high end security and has better performance with tasks while MySQL is a low end database manager.
One of the most important things to secure a database is to use a mature data abstraction layer that exists as close to the data as possible. MySQL is disqualified because it runs best when you minimize your abstraction layers to all but the most simple tasks. SQL Server abstraction layers are just fine to write. It is by far more mature than MySQL, but remember that MySQL is cheaper for web hosting firms and always include it with their packages.
If Microsoft does increase their market share within a web hosting firm that will provide additional revenue as well as allowing mobile devices designed with Visual Studio to gain access almost anywhere. The design and development of database software will be better off due to the fact that a complete database can be migrated from a Windows Platform to a Linux Platform, now that would be pretty awesome.
