To add a bit more information, all existing Ruckus Partners can login to Ruckus Cloud (cloud.ruckuswireless.com) and will be presented a "VAR" portal, today. No licenses required to get to that page. In order to get access as a Ruckus Cloud MSP partner, do reach out to your Ruckus PAM as suggested by Darrel, so they can get you started with some TEMP licenses so you can play with the new Cloud MSP features like creating customer accounts, distributing licenses, creating admins, customizing the portal that they see etc.
cheers
