Cloud management and controller-less functionality are valuable features. The Aerohive model aligns better with the increasingly mobile workforce (i.e. high concentration of remote offices and telecommuters). The new Hivemanager NG product is a 100% improvement, making configuration even easier.
Improvements to My Organization:
Competing products dependent upon controllers are a heavy lift. It can often seem as though you're managing a completely parallel network in addition to the wired LAN. This isn't the case with Aerohive. Most organizations don't have the human capital to spend on heavy management of a WLAN. Aerohive makes it much faster and easier to deploy. I had a a fully configured network (802.1X EAP/PEAP and guest SSIDs) deployed in a day. The built-in security features also make it much easier to provide compliance reports quickly.
Room for Improvement:
There are still some support issues with the branch routers and the newer version of Hivemanager. I also think the branch routers are due for a significant update.
We've had no issues with deployment.
We've had no issues with stability.
We've had no issues with scalability.
Dump Cisco and run, do not walk, to Aerohive. In my personal experience, the support staff and sales people are excellent and very helpful.
