MLOps open source has come a long way, offering a wide range of platforms and frameworks to choose from.

One of the most popular platforms is TensorFlow, developed by Google, which provides a robust set of tools for building and deploying machine learning models. TensorFlow is widely used and has a large community of developers who contribute to its growth.

Another notable platform is PyTorch, developed by Facebook, which is known for its ease of use and flexibility. PyTorch is particularly useful for rapid prototyping and has a strong focus on dynamic computation graphs.

TensorFlow and PyTorch are both widely used and have a large following, but they have different strengths and weaknesses, making it essential to choose the right one for your project.

MLOps Platforms

Let's start by exploring the open-source platforms for MLOps. These platforms are a great place to begin your machine learning journey.

In practice, it depends on the needs of your project and personal preferences. Ideally, once you get a full-fledged tool, you won’t have to set up any other tools.

Some examples of custom tools you might find in a full-fledged platform include a Custom TensorFlow job operator.

You can also use these platforms to monitor model performance.

Workflow Frameworks

Workflow frameworks are a crucial part of MLOps, providing a structural approach to streamline the different phases of your MLOps applications. They allow you to manage your workflow with ease and integrate platforms such as S3 and Azure Blob Storage to store your metadata.

Some popular workflow frameworks include Argo Workflow, Kubeflow, and Apache Airflow.

Kubeflow Alternatives

If you're looking for Kubeflow alternatives, you might want to consider open source solutions that offer more modularity.

Being "all-encompassing" can be a major drawback for enterprise platforms, making it harder to swap out individual components. This is why open source software is often more granular and focused on integrating with other platforms.

Open source solutions are like playing with Legos - if one part is giving you trouble, you can detach it and switch in an alternative. This level of flexibility is hard to find in monolithic enterprise platforms.

MLOps open source platforms are a great place to start your search for Kubeflow alternatives.

Proprietary platforms are incentivized to constantly sell upgrades and new features to existing customers, often by removing key features or adding limits to cripple your workflow until you pay for the next upgrade.

They might convince you that a low or mid-level plan suits your needs perfectly during sales, but only after buying in do you realize their limitations.

Proprietary platforms can raise their pricing with next-to-no notice, leaving your team to scramble to rewrite everything or pay more than you budgeted.

This can be a huge financial burden, especially for small teams or businesses on a tight budget.

In many cases, proprietary platforms are not upfront about their limitations, making it difficult to make an informed decision about whether to invest in them.
