Infra as Code vs VMSS

Guys, I always wondered... what is the difference between VMSS and create VMs via IAC? Which one is better? Does any of one have more advantages than the other?

Hi experi18,

absolutely correct, your VMs within the scale set are built automatically etc.
Nevertheless, in my view it is always sensible to create the infrastructure (resource group, VNet, subnet etc.) including the scale set via IaC.
The advantages are also for small environments: Sustainability, reproducibility, scalability and standardisation.
Please also remember that you need a data centre licence for Windows machines 😉

Yeah but, If I create a VMSS it would automatically be created standardised, no?

Why do create even the VMSS via IAC?
