What is the Use of MLOps?

Machine Learning Operations helps bridge the gap between model development and production deployment. It allows organizations to:

Automate ML Workflows: It ensures that organizations automate ML workflows through the process of taking ML models to production to reduce manual interventions and associated errors.
Improve Collaboration: It enables better collaboration among data scientists, developers, and operations teams during the ML lifecycle.
Monitor and Maintain Models: Conduct continuous monitoring for detection of drift issues in the model, and resolution of drift, to sustain the performance of the model.
Compliance: Provide transparency and traceability during the development and deployment of the model to meet governance and regulatory requirements.

Why do we need MLOps?

To begin the machine learning process, your company normally must first prepare data. You collect data from numerous sources and conduct tasks such as aggregation, duplicate cleansing, and feature engineering.

After that, you’ll utilize the data to train and validate the machine learning model. You can then use the trained and verified model as a prediction service, which other applications can access via APIs.

Exploratory data analysis frequently necessitates experimenting with several models before the optimal model version is ready for deployment. It results in frequent model deployments and data versioning. Experiment tracking and ML training pipeline management are required before your apps may incorporate or use the model in their code.

Machine learning life cycle

Machine Learning Operations is essential for managing the deployment of new ML models with modifications to application code and data in a systematic and synchronous manner. An optimum MLOps implementation treats ML assets in the same way that other continuous integration and delivery (CI/CD) environment software assets are handled. As part of a single release process, you deploy ML models alongside the apps and services they support, as well as those that use them.

What are the core principles of MLOps?

MLOps is built on four key principles that ensure efficient, scalable, and reliable machine learning workflows. These principles help organizations manage ML models effectively and reduce errors, improve automation, and enhance collaboration.

1. Version Control

Why it’s important:
Version control ensures that all ML assets (datasets, models, and code) are tracked and versioned. This makes it easy to reproduce results, rollback to previous versions, and audit changes.

How it works:

ML training code and model specifications go through a code review process.
Versioning tools like Git, DVC, and MLFlow track changes in code, data, and models.
Ensures reproducibility, meaning the same inputs will always produce the same outputs.

Example: If a new model version performs worse than the previous one, you can rollback to an earlier version without losing progress.

2. Automation

Why it’s important:
Automation helps ensure repeatability, consistency, and scalability across the ML lifecycle. It reduces manual work and speeds up the ML development process.

What can be automated?

Data ingestion and preprocessing
Model training and validation
Model deployment
Infrastructure management (using Infrastructure as Code – IaC)

Triggers for automation:

Data changes (e.g., new data is available)
Code updates (e.g., a new ML algorithm is introduced)
Monitoring alerts (e.g., model performance drops)
Scheduled retraining (e.g., weekly or monthly updates)

Tools Used: GitHub Actions, Airflow, MLFlow, DVC, Terraform (for IaC).

3. Continuous X (CI/CD/CT/CM)

Machine Learning Operations extends the principles of Continuous Integration and Continuous Deployment (CI/CD) from software engineering to machine learning.

Four Continuous Processes in MLOps:

Continuous Integration (CI): Automatically tests code, data, and models to ensure quality.
Continuous Delivery (CD): Deploys new models or services automatically to production.
Continuous Training (CT): Triggers model retraining whenever data changes.
Continuous Monitoring (CM): Keeps track of model performance, detects drift, and ensures accuracy over time.

Example: If a model’s accuracy drops below a certain threshold, MLOps can trigger automatic retraining and redeployment.

Tools Used: GitHub Actions, CML (Continuous Machine Learning), Evidently AI, Deepchecks.

4. Model Governance & Compliance

Why it’s important:
ML models must be secure, fair, and aligned with business goals. Governance ensures compliance with regulations and ethical AI practices.

Key aspects of model governance:

Collaboration: Ensuring data scientists, engineers, and business stakeholders are aligned.
Documentation: Keeping clear records of model decisions, datasets, and experiments.
Security & Access Control: Protecting sensitive data and managing who can deploy models.
Bias & Fairness Checks: Ensuring models do not discriminate against certain groups.
Model Approval Processes: Reviewing models before they go live, checking for risks and ethical concerns.

Example: Before deploying a credit-scoring model, a bank must check for bias and fairness to avoid discrimination against certain customers.

Tools Used: SHAP (Explainability), Fairlearn (Bias Detection), MLFlow (Model Governance).
