DevOps is a set of practices that aims to bridge the gap between software development and operations. It aims to improve collaboration and communication between these two teams and to automate the process of software delivery so that changes can be made and deployed more quickly and easily. This can include continuous integration, continuous delivery and infrastructure-as-code. The goal is to enable faster delivery of new features and improvements to customers while also improving the reliability and stability of the software.
What is MLOps?
Machine learning operations (MLOps) is the practice of applying DevOps principles and practices to machine learning projects. It involves the collaboration of data scientists, machine learning engineers and operations teams to streamline the process of building, testing, deploying and maintaining machine learning models in a production environment.
The goal of MLOps is to increase the speed and reliability of deploying ML models while also improving the overall quality of the models. This can be done by using tools such as version control, continuous integration and automation of the model deployment process.
Why DevOps is Not Enough: The Benefits of MLOps
Machine learning models have unique requirements, such as data privacy, version control and model deployment that are not addressed by traditional DevOps practices. MLOps is specifically designed to address these unique requirements and to ensure that machine learning models are deployed and managed in a production environment in a way that is consistent with other software components.
There are several benefits to implementing MLOps in a machine learning project, above and beyond the benefits of DevOps:
- Improved collaboration: MLOps promotes collaboration between data scientists, machine learning engineers and operations teams, which helps to ensure that models are deployed quickly and efficiently.
- Faster deployment: By automating the model deployment process and using continuous integration and continuous delivery (CI/CD) practices, MLOps can help to speed up the time it takes to deploy a model to production.
- Improved model quality: By using version control and automated testing, MLOps can help to ensure that models are thoroughly tested and of high quality before they are deployed to production.
- Better monitoring and maintenance: MLOps can help to improve the monitoring and maintenance of deployed models by providing better visibility into the performance of models and enabling easy rollbacks if necessary.
- Better model governance: MLOps can help to improve model governance by providing a clear process for the management of models, including versioning, testing, and deployment.
5 MLOps Tools to Help Transition From DevOps to MLOps
Making the move from DevOps to MLOps typically requires dedicated tools that can help manage the complexity of machine learning models and datasets. Here are a few tools, some open source and some commercial, that can help.
