I love Redis, I'm using it as a storage for my application. But as I develop my app further, I realized that Redis also has it's disadvantage. First of all, it's not really a database. Well, it can work like it. It's faster than it. But I still feel that the stability of a database is better compared to Redis. Also, searching. Damn! I can't search through Redis. Or maybe it's hard to search keys, indexes, or such in Redis. It's possible, but I don't like how it will be done.
To answer you question, just use Redis To Go (http://redistogo.com/). Well, it's not in Cpanel but I think it's better that way. :)
