When purchasing a Snapt Aria Essential or Growth license, you may notice that there is a limit to the number of backend servers per license which is an IP:port combination in the load balancer.
For example, if you have a 5 Upstreams/backend server license (Essential License) then you can only have up to 5 web servers behind the ADC’s load balancer.
The higher up in the tier of licenses, the more Upstreams/backends you will have available to you on your server unless you have purchased an Enterprise package that offers an unlimited amount of backend servers per license.
A Snapt Aria license can only be deployed onto a single server at a time, see Serializing a license for more information.
