Azure Machine Learning : Pricing details

Updated: Nov 19, 2021

There are many references explaining how to train a model on Azure Machine Learning. There're also plenty of documents demonstrating how to deploy the trained model. However, even for experienced users it may be challenging to know what will the final consumption look like. Azure pricing calculator is an excellent tool to predict the possible price, however, on Azure Machine Learning, there may be some underlying issues, that are not at all evident. In this short article we are going to uncover some of these hidden facilities. Up we go!

Compute Pricing

The price is mainly impacted by compute resources associated with Azure Machine Learning Services. They vary by configuration and family, and should be chosen according to the usage context. For instance, huge language models like BERT will require GPU instances due to their volume. On Azure Machine Learning there are compute clusters and compute instances.

A managed compute resource is created and managed by Azure Machine Learning. This compute is optimized for machine learning workloads. Azure Machine Learning compute clusters and compute instances are the only managed computes.

You can create Azure Machine Learning compute instances or compute clusters from:

When created, these compute resources are automatically part of your workspace, unlike other kinds of compute targets.

Note : When a compute cluster is idle, it autoscales to 0 nodes, so you don't pay when it's not in use. A compute instance is always on and doesn't autoscale. You should stop the compute instance when you aren't using it to avoid extra cost..

For more details on pricing for computational instances, please refer to the official documentation.

Deployment Pricing

If Azure Machine Learning is only used for model deployment, the steps performed by Azure Machine Learning are:

  1. Build a Container Image for the trained model

  2. Deploy the model to "dev" using Azure Container Instances (ACI)

  3. Deploy the model to production using Azure Kubernetes Service (AKS)

All these steps do not involve compute instance creation, so no computational cost is considered. More details are provided in the next session (Managed compute resource).

If you train your model locally and deploy it as web service using the SDK, on your instance three resources will be deployed that will incur additional charges

  • Azure Container Registry Basic account

  • Azure Block Blob Storage (general purpose v1)

  • Key Vault

Azure Container Registry Basic account

Here's an example of Container Registry

Region: West Europe

Currency: US Dollar

Azure Block Blob Storage (general purpose v1)

Region: West Europe

Currency: US Dollar

Data storage prices pay-as-you-go

All prices are per GB per month.

Key Vault

Vaults are offered in two service tiers—standard and premium.
