Machine Learning Operations (MLOps) on AWS

Introduction to MLOps

• Machine learning (ML) has been transforming our lives for the past 75-80 years.
• ML is used in various applications, such as product recommendations, fraud detection, etc.
• MLOps is about creating and keeping ML models productionized for a long period of time.

Key Considerations and Challenges in MLOps

• Cultural challenges, lack of cross-functional teams, and different priorities/needs of people.
• Requirement of diverse skillsets, including ETL engineers, data scientists, governance officers, etc.
• MLOps is not just about technology, but also involves people and processes.
• Minimizing human intervention and automating the ML lifecycle is the goal of MLOps.

ML Lifecycle and MLOps Process

1. Business Problem to ML Problem: Identifying if ML is the right solution for the problem.
2. Data Collection and Preparation: Spending most of the time on data collection and cleaning.
3. Feature Engineering: Increasing the predictive power of the model.
4. Model Training and Tuning: Training the model and evaluating its performance.
5. Model Deployment: Deploying the model to production.
6. Model Monitoring: Constantly monitoring the model's performance and retraining as needed.

Differentiating DevOps and MLOps

• DevOps is mainly about code, while MLOps extends it to include data and models.
• MLOps involves managing data, code repositories, and model versions.

Organizational Roles in MLOps

• Data Engineers, Data Scientists, MLOps Engineers, Governance Officers, and Model Approvers.
• Collaboration and communication between these roles is crucial.

MLOps Technology Implementation Considerations

• Consistency, flexibility, reproducibility, scalability, and explainability are important factors.
• AWS SageMaker provides a comprehensive set of features for MLOps.

Security and Governance in MLOps

• Security is a key consideration from the beginning of the pipeline.
• SageMaker provides features for network isolation, authentication, authorization, data protection, and compliance.
• ML governance is important for standardizing processes, monitoring model behavior, and ensuring explainability.

MLOps Maturity Model

• Four stages of MLOps maturity: Initial, Repeatable, Reliable, and Scalable.
• Organizations are typically in the Initial or Repeatable phases, with some in the Reliable and Scalable phases.

Demonstration of an MLOps Pipeline using AWS SageMaker

• Demonstration of a pipeline using AWS CodePipeline, CodeBuild, SageMaker, and Step Functions.
• The pipeline is triggered by data updates, code changes, or other events, and automates the ML lifecycle.

Key Takeaways

• MLOps is a journey, not an end.
• Adopt MLOps practices with SageMaker, build CI/CD pipelines, and automate as much as possible.
• Take advantage of AWS resources, such as documentation, training, and certification discounts.
