Project-5: End-to-End Production MLOps Pipeline on AWS EKS

Architecting, Training, Containerizing & Deploying an IT Career Upskilling Prediction ML Model using Python, Scikit-Learn, FastAPI, Docker, Kubernetes & AWS EKS

Real-Time Production Project | MLOps & Kubernetes Infrastructure

🤖 Project Overview & MLOps Philosophy

Building a machine learning model inside a Jupyter Notebook represents only 10% of the effort in real-world artificial intelligence projects. The remaining 90% involves operationalizing the model: data versioning, containerizing prediction APIs, orchestrating CI/CD pipelines, scaling deployments on managed Kubernetes clusters, and monitoring model performance against real-time data drift.

❓ Frequently Asked Questions (FAQ) & Interview Guide

Common real-time production & interview questions on MLOps pipeline deployment:

Q1: What is the main difference between DevOps and MLOps?

Answer: DevOps focuses on continuous integration and deployment of source code. MLOps extends DevOps to handle Code + Data + Machine Learning Models. In addition to software CI/CD, MLOps automates data versioning, model training, accuracy evaluation, continuous retraining, and monitoring for data/concept drift.

Q2: Why use FastAPI instead of Flask or Django for ML Model Serving?

Answer: FastAPI is built on ASGI (Asynchronous Server Gateway Interface) using Starlette and Pydantic. It provides high performance matching NodeJS/Go, auto-generates OpenAPI interactive Swagger documentation, and enforces data type validation out of the box, making it ideal for high-throughput ML inference APIs.

Q3: How do you handle Model Versioning in production MLOps?

Answer: Model versioning tracks trained model artifacts (.pkl, .onnx) alongside dataset versions and hyperparameters. Tools like MLflow Model Registry, DVC (Data Version Control), or S3 bucket versioning tag each model binary with commit hashes, allowing instant rollbacks if a newly deployed model exhibits accuracy degradation.

Q4: What is Data Drift vs. Concept Drift in Machine Learning Monitoring?

Answer: Data Drift: Occurs when incoming production input data distribution changes compared to training data (e.g., user demographic shift).
Concept Drift: Occurs when the statistical relationship between input features and target labels changes over time (e.g. consumer purchasing habits post-pandemic). Monitoring tools like Evidently AI or Prometheus trigger pipeline retraining when drift is detected.

Q5: Why deploy ML models on Kubernetes (EKS) instead of a simple VM?

Answer: Kubernetes provides horizontal pod autoscaling (HPA) to handle traffic spikes during peak inference hours, self-healing pod restarts if an API worker crashes, zero-downtime rolling deployments for model updates, and declarative resource management across multi-AZ clusters.

Q6: How do you containerize ML models cleanly using Docker?

Answer: A production Dockerfile copies the serialized model file (it_package_model.pkl) and API server code into a lightweight base image (e.g. python:3.10-slim), installs pinned dependencies via requirements.txt, exposes prediction ports (e.g. 8000), and runs uvicorn main:app --host 0.0.0.0 --port 8000.
