Virtual Machine Recommendations for SBC SWe Lite running in AWS.

WARNING: USE RECOMMENDED AWS VM INSTANCES FOR RELIABLE PERFORMANCE

The recommended hardware and software settings are intended to ensure optimum stability and performance. If the recommended settings are not used, the SBC SWe Lite may not behave as expected. Ribbon does not provide support for SBC SWe Lite instances deployed in non-recommended AWS VMs. For more information regarding the recommended AWS VM instances, please refer to https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-recommendations.html.


  • 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 host.

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