Azure ML (AML) Alternatives for MLOps

Azure Machine Learning (AML) is a cloud-based machine learning service for data scientists and ML engineers. You can use AML to manage the machine learning lifecycle—train, develop, and test models, but also run MLOps processes with speed, efficiency, and quality.

For organizations that want to scale ML operations and unlock the potential of AI, tools like AML are important. An all-in-one solution like AML simplifies the MLOps process. Creating machine learning solutions that drive business growth becomes much easier.

But what if you don’t need a comprehensive MLOps solution like AML? Maybe you want to build your own stack, and need specific tools for tasks like tracking, deployment, or for managing other key parts of MLOps? You’re in luck – in this article, we’re reviewing multiple alternatives to Azure Machine Learning (AML) for MLOps.

What does Azure ML really do?

To find alternatives for AML, first, we need to analyze exactly what AML does:

  1. Experiment Tracking
  2. Model Management
  3. Model Deployment
  4. Model Lineage
  5. Model Monitoring
  6. Data Labelling

1. Experiment tracking

Experiment tracking documents every piece of information that you care about during your ML experiments. Machine learning is an iterative process, so this is really important. 

Azure ML provides experimental tracking for all metrics in the machine learning environment. Setting the AML workspace to pull the required data makes it easier to replicate experiments and compare results.

2. Model Management

Model Management in machine learning is about managing every process in the ML lifecycle from model creation to model deployment. It’s a fundamental part of any ML pipeline. AML is used to manage models in the machine learning project cycle. Effective model management uses log entries and model/data versioning to create a better environment for experiments.

With Azure ML, you can control experiments and enhance collaboration among scientists. This tool records the parameters associated with your experiments in a central location, where you can see each model and reproduce it if you want.

3. Model Deployment 

Model deployment makes your models usable for people. Model deployment in machine learning operations often gets complicated and challenging because of the computing power and resources it requires. In this area, Azure ML is particularly helpful.

With the Azure ML Studio, you can deploy your ML models to the cloud, transform them into a web service, and expose them to testing. Additionally, it assists with packaging and debugging your app before sending it to the cloud, and improves the success rate of your deployment.

4. Model and Data Lineage

A big issue for data scientists and ML engineers is feeding accurate data to their models. Azure ML is useful for handling models and data lineage in the machine learning process. Azure ML monitors model history and tracks changes in the data it uses. 

You can see how a model—and the data that fuels it—-evolve as they pass through phases in the ML production cycle. Model and data lineage is important because it helps you improve the quality of data used by your production models. This reduces the chances of incorrect predictions, making the model more valuable.

5. Model Monitoring

Efficient model monitoring makes it easier to find problems before your model reaches production. A robust MLOps platform like Azure ML can help you monitor drifts in datasets, historical model performance changes, fairness and bias, and other key indicators.

Production teams are often faced with monitoring the predictive performance of models, as errors could lead to adverse economic impact, a decline in user trust, and increased exposure to risk. The Azure Monitor makes life easier for professions by logging data metrics and activity records. This way, you can closely track your models and know when their predictive performance starts to drop.

6. Data Labeling

Data labeling is the process of tagging raw data for better training. Labeling in AML is good when it comes to creating, managing, and monitoring data labeling projects. It works with images and text data. You can set up labels for image classification, object detection (bounding box), or instance segmentation (polygon).

In Azure ML, you can select a vendor labeling company from Azure Marketplace. You can upload your local dataset to Azure Storage Explorer.

  • Coordinate data, labels, and team members to efficiently manage labeling tasks.
  • Tracks progress and maintain the queue of incomplete labeling tasks.
  • Start and stop the project and control the labeling progress.
  • Review the labeled data and export as an Azure Machine Learning dataset.

Azure Machine Learning is a great suite, but it can be overwhelming if you have very specific needs, or don’t need the options that Azure provides. 

In G2 Crowd reviews of the Azure ML, users have mentioned that :

  1. Azure ML doesn’t meet the requirement for their specific use case; it’s not so flexible and customization can be hard.
  2. It’s difficult to integrate the data for creating the model with Azure.
  3. It’s expensive compared to other platforms.
  4. Its execution speed is quite slow.
  5. It’s only available online, and you need a strong internet connection to work effectively with Azure Machine Learning Studio.

So, here are multiple alternative tools that you should like!

The Best MLOps Tools and How to Evaluate Them

12 mins read | Jakub Czakon | Updated August 25th, 2021

In one of our articles—The Best Tools, Libraries, Frameworks and Methodologies that Machine Learning Teams Actually Use – Things We Learned from 41 ML Startups—Jean-Christophe Petkovich, CTO at Acerta, explained how their ML team approaches MLOps.

According to him, there are several ingredients for a complete MLOps system:

  • You need to be able to build model artifacts that contain all the information needed to preprocess your data and generate a result. 
  • Once you can build model artifacts, you have to be able to track the code that builds them, and the data they were trained and tested on. 
  • You need to keep track of how all three of these things, the models, their code, and their data, are related. 
  • Once you can track all these things, you can also mark them ready for staging, and production, and run them through a CI/CD process. 
  • Finally, to actually deploy them at the end of that process, you need some way to spin up a service based on that model artifact. 

It’s a great high-level summary of how to successfully implement MLOps in a company. But understanding what is needed in high-level is just a part of the puzzle. The other one is adopting or creating proper tooling that gets things done. 

That’s why we’ve compiled a list of the best MLOps tools. We’ve divided them into six categories so you can choose the right tools for your team and for your business. Let’s dig in!
