Things to pay attention to when doing MLOps for the first time
MLOps, or Machine Learning Operations, involves the management of the entire lifecycle of machine learning models, from development to deployment and maintenance. If your company is just starting with MLOps, here are some important points to keep in mind.
Start with a clear goal
Before you begin, make sure you have a clear goal in mind. What do you hope to achieve with MLOps? Define your objectives, and make sure they align with your company's overall goals. Your goals will be different if you have a small team of engineers (ML, data, software) versus having a large team as well as your needs. You may want to decide early on to use off the shelf / open-source or commercial tools or build tools internally.
Build a strong team
Building a strong MLOps team is crucial for success. Hire experienced data scientists, machine learning engineers, DevOps professionals, and data engineers who can work together to develop, test, deploy, and maintain machine learning models. Work on smaller sample projects as a team to make sure the team members understand each other well and can understand the language of each domain. Remember the mindsets of the data scientist, ML engineer, data engineer, and DevOps engineer are different. They look at the problems and solutions differently. Make sure your team members are aligned.
Invest in infrastructure
MLOps requires a robust infrastructure that can support the development, testing, and deployment of machine learning models. Invest in the right tools and platforms, such as cloud computing, containerization, and orchestration technologies. What you choose in this space depends on your needs, the size of the team, and the requirements of your organization and projects.
Implement version control
Version control is essential in MLOps to keep track of changes made to code, data, and models. Use tools like Git to track changes, manage branches, and collaborate with team members. Use an artifact registry to keep track of data, models, metadata, and any other artifacts related to your model lifecycle.
Ensure data quality
Data is the fuel that powers machine learning models. Ensure that your data is of high quality, accurate, and reliable. Implement data governance policies, and use data validation and monitoring tools to detect and address issues. Make sure you can detect if a model, data, or concept drift happens. Keep close relationship with the business and domain experts to have a constant quality review of data (in your dataset, and production).
Monitor and evaluate models
Monitoring and evaluating models is critical to ensure their accuracy, reliability, and performance. Use tools like metrics trackers and dashboards to track model performance and identify issues. Make sure you have processes such as A/B testing capabilities which you can evaluate the models in production. Do not just rely on the model performance metrics during the experimentation phase.
Implement automation
Automation is key to scaling MLOps. Use automation tools like continuous integration and continuous deployment (CI/CD) to streamline the development, testing, and deployment of machine learning models. There are best practices software engineering processes and tools for the automation which can be reused in machine learning projects.
Ensure security and compliance
Security and compliance are critical in MLOps, especially when dealing with sensitive data. Implement security best practices, such as encryption, access controls, and vulnerability management, and ensure compliance with regulations like GDPR and HIPAA.
If it is the first time that your company wants to use MLOps and have a full lifecycle for its ML models and it has limited resources, you can start small. You can integrate some level of monitoring and tracking into your ML workflows and gradually add the components mentioned in this article. Make sure you implement you projects in a way that they will be maintainable, extendable, and flexible. The technologies will change and will need to adapt your MLOps project constantly to keep-up with the latest best practices.
