Demo PV Performance

The purpose of this repository is to measure performance differences between PVs on AKS:

• PV mounted from Azure data lake Gen2 (data resides remote to the node)
• PV local to the node (data resides on the node)

How to conduct the experiment

• Setup Azure infrastructure

  • AKS cluster
  • Storage account #1 (Azure datalake gen2)
  • Storage account #2 (Azure files)
  • Storage account #3 (Azure blob store)

• Deploy four instances of a web API with GET endpoint to retrieve data from the four different storage solutions

• Use k6 to measure performance differences between the four instances

Github secrets needed by CICD

• AZURE_CREDENTIALS: Generated by az ad sp create-for-rbac --name "demo" --role contributor --scopes /subscriptions/<subscription id>/resourceGroups/<resource-group> --json-auth

Setup

• Make sure the AKS can access ACR: az aks update -n <name aks> -g <aks resource group> --attach-acr <name of acr>
• Store latest ACR url and credentials in github repo secrets ACR_REGISTRY_URL, ACR_USERNAME and ACR_PASSWORD
• Store latest storage account access key in github repo secret STORAGE_ACCOUNT_KEY
