Simplicity and performance. Really quick / easy to stand up new services, and the system requirements are low. Clustering for high-availability takes seconds once the base systems have been built. Review collected by and hosted on G2.com.

No real problems noted. For our use case, it's done everything we need it to do. I guess some enhanced reporting capability would be nice, to make it easier to detect trends over a period of time. Review collected by and hosted on G2.com.
