• Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all virtual machines (VMs) to run in AWS. Minimal networking configuration requires the Management Network Interface and at least one media interface to be assigned. To use a separate Media Interface for each peer (phone system, SIP trunking provider, etc.) select a VM size with a higher number of Network Interfaces.
• Allocate each VM with only as much virtual hardware as that VM requires. Provisioning a VM with more resources than it requires can, in some cases, reduce the performance of that VM as well as other virtual machines sharing the same hostAdding excess resources may not result in improved performance nor will improved performance or feature difference be supported. Refer to the SBC SWe Edge Performance and Capacity for sanctioned VM sizes and supported performance against sanctioned VMs.

• The vNIC recommendation is from 2 vNIC to 4 vNIC. See below for guidelines.
