Utilizing two Redis instances - Similar to Mongos
===

I have been reading that the proper way to scale Redis is to add a Separate instance (Even on the same machine is ok because CPU intensive).  What I am wondering is if there are any existing components out there that facilitate the round robin / write / read similar to Mongos so that I could just call into it and it would properly write / read to one of the underlying instances.  I realize that it is more complicated that what I have represented above, but didn't want to re-invent the wheel by trying to write my own proxy, etc to handle this.

Any suggestions / tips, etc would be appreciated.

Thanks,

S
