Price Difference between Azure ML vs Azure VM

Question

Hi,
our team is using AzureML for company's Machine Learning project.

My question is this:

What's the price difference between AzureML and AzureVM when executing python script?

if we use AzureVM, we may use Azure Registry together, i think.

Because our team is newbie in Azure, we are unfamiliar with this price policy

thanks.

Depending upon your requirement there are different possibilities.

Now as per your statement you want to understand cost associated with Azure ML and Azure VM for running Python Script.

Now as such for Machine Learning on Azure the Machine Learning surcharges are free and you are only charged for series of VM you use.

It has been best described in example here:

You will be billed daily. For billing purposes, a day commences at midnight UTC. Bills are generated monthly.

Training:
As a specific example, let’s say you train a model for 100 hours using 10 DS14 v2 VMs on an Basic workspace in US West 2. For a billing month of 30 days, your bill will be as follows:

Azure VM Charge: (10 machines * $1.196 per machine) * 100 hours = $1,196

Azure Machine Learning Charge: (10 machines * 16 cores * $0 per core) * 100 hours = $0

Total: $1,196 + $0 = $1,196

Inferencing:
As a specific example, let’s say you deploy a model for inferencing all day for a 30-day billing month using 10 DS14 v2 VMs in Basic in US West 2. For a billing month of 30 days, your bill will be as follows:

Azure VM Charge: (10 machines * $1.196 per machine) * (24 hours * 30 days) = $8,611.20

Azure Machine Learning Charge: (10 machines * 16 cores * $0 per core) * (24 hours * 30 days) = $0

Total: $8,611.20 + $0 = $8,611.20

This already includes the use of VM.

Now the other scenario you are talking about is around deployment of Python App where you might need to make use of containers and the cost associated with them which is a seperate topic.

Now let us come to your basic question where I do assume that you might want to explore the options available to you for running Python Script in Azure.

Both Azure Automation and Azure Functions support running Python scripts and do not require the creation of any VM's for same.

For Azure Function you can refer to this. and for cost you can refer to this.

For Azure Automation you can refer to this. For cost incurred for automation you can refer to this which mostly depends upon the Job you create.

Now if you check both the option they are not billed particularly for Python script you are running but more around resources being used for what time which you can have a rough estimation from Pricing calculator links mentioned in above links.

Further now if you want to deploy or run your Python App in Azure there are mainly 4 ways as mentioned here:

• Create a simple Python web app on Azure
• Build and deploy a serverless Python app
• Try Azure Machine Learning scenarios in a preconfigured environment
• See more ways to use Python on Azure

You don't need to worry about the Python script incurring you charges but you can check the price of associated resource you are using basically any Azure resource here on Pricing Calculator as well.

Hope it helps :) !!!
