What is MLOps?
MLOps, short for Machine Learning Operations, is a framework that merges principles from DevOps (software development and IT operations) with the specialized needs of the machine learning lifecycle. It encompasses practices, tools, and processes aimed at automating and streamlining the deployment, monitoring, and maintenance of ML models in production. By integrating machine learning, software engineering, and operations, MLOps enables a seamless workflow that accelerates ML project delivery and reliability.
The primary objective of MLOps is to bridge the gap between data scientists and IT teams, ensuring that models can be deployed quickly, consistently, and at scale. This approach is essential for organizations seeking to leverage AI and ML effectively in their operations, allowing them to unlock the full potential of machine learning while minimizing operational challenges and maximizing model performance.

Key Components of MLOps
- Version Control & CI/CD: Tracking code, data, and model changes with version control. CI/CD (Continuous Integration/Continuous Delivery) automates builds, testing, and deployment.
- Orchestration: Managing complex workflows and dependencies in the MLOps process.
- Experiment Tracking & Model Registries: Recording experiments, hyperparameters, and results. Model registries store and manage different model versions.
- Data Lineage & Feature Stores: Tracking data sources and transformations for auditability. Feature stores manage and share processed data for model training and serving.
- Model Training & Serving: Automating model (re)training, packaging, and deployment for real-time or batch predictions.
- Monitoring & Observability: Monitoring model performance, data drift, and system health to detect issues and maintain model accuracy.
- Infrastructure as Code: Managing and provisioning infrastructure (servers, storage, etc.) using code for consistency and ease of scaling.

What Does an MLOps Engineer Do?
An MLOps engineer sits at the intersection of data science, software engineering, and IT operations. While data scientists focus on building and training models, and software engineers focus on application development, the MLOps engineer ensures that ML models actually work reliably in production — at scale.
Day-to-day responsibilities include:
- Building and maintaining data and ML pipelines that automate the flow from raw data to model predictions
- Containerising models and deploying them as APIs (real-time) or batch jobs
- Setting up monitoring systems to track model performance, data drift, and system health
- Automating model retraining when performance degrades or new data arrives
- Collaborating across data science, engineering, and operations teams to ensure smooth handoffs
- Managing version control for code, data, models, and configurations
- Optimising infrastructure costs while maintaining low-latency inference
- Increasingly, operationalising LLMs and building RAG (Retrieval-Augmented Generation) pipelines in production

FAQs
Q: Is MLOps the future of machine learning development?
Yes. As more companies deploy ML models in production, MLOps practices become essential for ensuring reliability, scalability, and continuous improvement. In 2026, the field has expanded to include LLMOps for large language models, making MLOps skills even more valuable and future-proof.
Q: What is LLMOps and how is it different from MLOps?
LLMOps applies MLOps principles to large language models. Beyond classic model deployment, it adds LLM-specific concerns: serving and scaling large models, building RAG pipelines, managing prompts and versions, evaluating outputs (RAGAS, LLM-as-judge), adding guardrails, and monitoring cost, latency, and tokens. It’s widely seen as the 2026 evolution of MLOps.
Q: How long does it take to become an MLOps engineer?
Typically 6–12 months if you already know some programming or ML.
A structured path runs foundations → ML basics → DevOps → MLOps core → orchestration/serving → monitoring → LLMOps.
Most learners become job-ready in 6–9 months with hands-on projects. The portfolio matters more than raw study time.
Q: What does an MLOps engineer do day to day?
They build and maintain pipelines that take ML models from notebooks to production — automating training, deployment, and retraining; versioning data and models; setting up monitoring for drift and performance; and collaborating across data science, engineering, and operations teams. Increasingly, the role also covers operationalising LLMs (LLMOps).
Q: Which tools should I learn for MLOps in 2026?
Core: Git, Docker, Kubernetes, MLflow, DVC, Airflow or Kubeflow, and a cloud platform (AWS/GCP/Azure). For monitoring: Prometheus, Grafana, Evidently. For the 2026 LLMOps layer: LangChain/LangGraph, LangSmith, a vector database, and an LLM serving tool like vLLM or BentoML.
Q: What are common MLOps interview questions?
Expect questions on MLOps vs DevOps, data/model versioning, batch vs real-time serving, model drift detection and handling, retraining strategies, and tool comparisons (MLflow vs Kubeflow). See the interview questions section above for 13 detailed questions with answers.
Q: What is the salary of MLOps professionals in India?
MLOps salaries in India range from ₹6–12 LPA for junior roles (0–2 years) to ₹25–45+ LPA for senior roles (5–8 years), with MLOps leads earning ₹45–70+ LPA. MLOps typically commands a 20–35% premium over generic DevOps roles due to the specialised skill set combining ML and production engineering.
Q: What are the main differences between MLOps and DevOps?
MLOps extends DevOps to handle the unique challenges of machine learning: managing data dependencies, tracking experiments, model-specific monitoring, handling model drift, and automated retraining cycles. While DevOps focuses on code deployment and system reliability, MLOps must also manage models, data pipelines, and the continuous learning loop that keeps models accurate over time.
