yes, VNF is a kind of an software appliance which is meant to be configured through different interfaces.

Yes. Radiator VNF is not restricted to using CentOS, but we are using CentOS as a base Linux distribution 
for Radiator VNF. Adaptation for Ubuntu/Debian will require some work but it is feasible.

Yes, patches can be applied and do not void warranty/support.

Radiator VNF is meant for AAA cases which require scaling for performance, either 
automatically or manually.

Yes. Modules can be updated and more modules can be installed.

Radiator VNF does not have any strict requirements. Currently we are running Radiator VNF on 
OpenStack, but it can also be adapted to run on a bare metal hardware or in VMware vCloud.

Default minimum HA setup of Radiator VNF consists of 11 virtual machines:

- 2 Radiator load balancers (RADIUS or Diameter)
- 2 Radiator AAA workers (number of workers scales according to load)
- 3 Database/message broker nodes
- 2 External database connector nodes (LDAP, SQL, RADIUS or Diameter)
- 2 Management nodes

With OpenStack, creating Radiator VNF stack is automated through its Heat orchestration.
