MLOps Life Cycle
MLOps, or Machine Learning Operations, refers to the practice of collaboration and communication between data scientists and operations professionals to help manage and automate the end-to-end machine learning lifecycle.
Here are the steps for MLOps along with the tools, tasks, and goals associated with each step:
Data Management
Tasks:
- Data Collection
- Data Cleaning
- Data Labeling
- Data Versioning
Tools:
- Apache Kafka, Apache Nifi (Data Ingestion)
- Pandas, Apache Spark (Data Processing)
- Labelbox, Dataloop (Data Labeling)
- DVC, Delta Lake (Data Versioning)
Goals:
- Ensure high-quality data
- Maintain consistent data versions
- Provide reproducible data pipelines
Model Development
Tasks:
- Exploratory Data Analysis (EDA)
- Feature Engineering
- Model Training
- Hyperparameter Tuning
Tools:
- Jupyter Notebooks (EDA)
- Scikit-learn, TensorFlow, PyTorch (Model Training)
- Keras Tuner, Optuna (Hyperparameter Tuning)
Goals:

- Ensure model reproducibility
-
Model Versioning and Experiment Tracking
Tasks:
- Model Versioning
- Experiment Tracking
Tools:
- MLflow, DVC (Model Versioning)

- Detect and log errors
-
Continuous Integration and Continuous Deployment (CI/CD)
Tasks:
- Automated Testing
- Automated Deployment
Tools:
- Jenkins, GitHub Actions, GitLab CI/CD (CI/CD Pipelines)
- ArgoCD, Spinnaker (Continuous Deployment)
Goals:
- Automate testing and deployment processes
- Ensure reliable and repeatable deployment pipelines
-
Model Retraining and Feedback Loop
Tasks:
- Model Performance Evaluation
- Data Drift Detection
- Model Retraining
Tools:
