We categorized 40+ MLOps tools and here's what we found!

Getting your machine learning models out of the lab and into the real world can be tough. Deploying them, keeping them running smoothly, and making sure they stay accurate are all challenges that need to be solved.

This is where MLOps comes in.

MLOps is a set of practices that help you manage the entire lifecycle of your ML models, from development to deployment and beyond. Now, there are a ton of MLOps tools out there, each with its own strengths and quirks. Choosing the right ones for your needs can feel overwhelming.

That's why we wrote this article - to serve as a guide to the MLOps landscape.

We'll break down the key things to consider when choosing MLOps tools and give you a rundown of some of the most popular options. We'll also look at what the future holds for MLOps, so you can stay ahead of the curve.

Without further ado, let's dive into it!

What is MLOps software?

MLOps software is a suite of tools and practices designed to streamline the deployment, monitoring, and management of machine learning models in production environments, ensuring they perform reliably and efficiently.

An MLOps platform is made up of several key components that work together to streamline and automate the machine learning lifecycle. These components include:

• A central repository for storing and managing trained machine learning models also called a model registry
• A feature store is a centralized repository for storing and accessing features. Features are the input variables used by machine learning models.
• A database for tracking experiments, model lineage, and other metadata related to machine learning models, also called a metadata sore.
• An orchestration tool, which is a tool for automating the execution of machine learning workflows, including data preparation, model training, and model deployment.
• Model monitoring using a tool for tracking the performance of machine learning models in production and detecting issues such as model drift or data drift.
• A model deployment tool for deploying machine learning models to production environments, such as cloud platforms or on-premises servers.

MLOps tools offer several benefits, including:

• Faster development and deployment of ML models,
• Improved collaboration between data scientists and other stakeholders,
• Increased automation of ML tasks,
• Better monitoring and logging of model performance,
• Enhanced reproducibility of ML experiments.

Now, armed with this knowledge, let's dive into the rich landscape of MLOps tools!

MLOps tools landscape

The MLOps landscape is continuously evolving, with new tools and technologies emerging regularly. It is essential to stay updated on the latest advancements and evaluate tools based on specific requirements and compatibility with existing workflows.

In the following section, we explore the diverse landscape of MLOps tools, categorizing them based on their primary functions and deployment models. Within each stage, the tools are further categorized based on whether they are commercial, open-source or source-available.

We’ve identified 5 key stages for an end-to-end MLOps workflow:

1. Data preparation, which involves collecting, cleaning, and preparing data for use in machine learning.
2. Model development focuses on creating ML models suitable for the task.
3. Model training and retraining involves using the prepared data, or in the case of retraining, live data, to train the developed ML models.
4. Monitoring and evaluation involves tracking the performance of machine learning models in production. It also involves setting up alerts in response to detected issues.
5. Deployment involves integrating ML models into production systems. This step can involve packaging and containerization of the ML models.

The tools listed in each category are not exhaustive but represent a selection of popular and effective tools commonly used in MLOps pipelines. It's also important to note that many of these tools don't fit neatly into a single category and may offer complementary or overlapping functionality. In such cases, we've categorized them based on their primary function within the MLOps workflow.
