Azure Terraform Lab - az-tfl-vnetpeer-perf - Network Performance between VMs in different VNets, across VNet peerings

Topology

Resources created

This Lab creates the following Azure resources (prefix 'cg' used for names):

Use-Cases

• Measure network performance (e.g. throughput, latency) between VMs (Oracle Linux) in different VNets across VNet peerings
• qperf is installed and firewalld is disabled on both VMs
• You may use ping, iperf3 or other network performance tools (may have to be installed)

Usage

• Authenticate with Azure (e.g. Azure CLI) and switch to the appropriate subscription (az account set -s )
• Configure appropriate values for the variables in terraform.tfvars
• terraform init
• terraform apply
• Evaluate/Test/Demo
• terraform destroy

Example - qperf

• On vm1, use qperf to listen

sudo qperf

• On vm2, use qperf to connect to vm1 (private IP) and test TCP bandwidth and latency for 10 seconds

sudo qperf <vm1 private IP> -t 10 tcp_bw tcp_lat
