Why? Why don't you use Microsoft SQL Server? I mean, your company decided that for sound economic reasons, Microsoft is the way to go. You did read all those reports that even though linux is free, it has a much higher TCO than Windows. Why do you think the same is not true of Redis? I think you are one of those malcontents that is not aware of economic reality. Sure, Redis can probably do on one box what will take months of tuning several SQL Server boxes. But that's the great lie of linux. It just looks easier to begin with. Much better to just pay Microsoft, and have a technology monoculture. It keeps staff costs down too.
