Benefits of using APs without Wireless Controller and based on Cloud

Hello Guys,

I need to specify the drawbacks of using a WLC and make sure the below is right:

1- Once you use a WLC then the traffic is encrypted between the AP and WLC, Therefore when the CAPWAP tunnel passes through the DC firewall it will not be inspected and that's a security issue.

2- All the user traffic is terminated on the WLC via the CAPWAP which means if your WLC has 1G port this will limit the traffic a lot. However, if there is no WLC, you'll be able to use the full port speed of the AP.
