Azure Terraform Lab - az-tfl-vnet-perf - Network Performance between VMs in a VNet

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 the same VNet
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
