Jeremy,
Not sure what your goals and objectives are, but you might want to take a look at
ExtremeCloud.
Our 802.11ac Wave 2 access point can be provisioned and managed by ExtremeCloud so you don't need any controller to manage your Wireless LAN infrastructure. Additionally, the Access Points run the same software, so if your business imperatives drive you to transform from Cloud-Managed to Local-Controller-Managed, you can continue to operate using the same Access Points.
Let me know if you have any questions - Happy to discuss specifics with you.
Best,
Thomas.
