You don’t need to invest heavily in MLOps tools to integrate the benefits of DevOps into your machine learning projects. There are many open-source tools available that can help you achieve this. These tools are particularly valuable when you’re tackling unique challenges and need a supportive community. However, there are also several advantages to using open-source machine learning tools.
Open-source tools offer greater privacy and control over your data and models. However, you will need to manage, deploy, and maintain these tools yourself, which may require additional personnel. Additionally, you will be responsible for security and handling any service outages.
