What is MLOps?

By the Appsierra Knowledge Desk

Reviewed by senior engineers · Updated September 2026

MLOps, short for machine learning operations, is a set of practices for reliably building, deploying, and maintaining machine learning models in production. It applies the automation and collaboration principles of DevOps to the unique needs of ML, where data and models change over time. MLOps helps teams move models from experimentation to dependable, monitored operation at scale.

Why is MLOps necessary?

Building a machine learning model in a notebook is very different from running it reliably in production. Models depend on changing data, can degrade over time, and need retraining, versioning, and monitoring. Without disciplined practices, ML projects often stall before delivering value or break silently after launch. MLOps brings structure to this lifecycle, automating training, deployment, and monitoring so models stay accurate, reproducible, and maintainable as conditions evolve in the real world.

How does MLOps differ from traditional DevOps?

MLOps extends DevOps but handles complications unique to machine learning. Beyond code, ML systems version data and models, which change independently and affect results. Models can drift as real-world data shifts, requiring monitoring of accuracy, not just system health, and periodic retraining. Reproducibility is harder because outcomes depend on data, code, and configuration together. MLOps adds practices for data and model management, experiment tracking, and continuous monitoring on top of standard DevOps automation.

What does the MLOps lifecycle include?

The MLOps lifecycle spans data preparation, model training and experimentation, validation, deployment, and ongoing monitoring. Pipelines automate moving a model from development to production, while versioning tracks data, code, and models for reproducibility. Once deployed, monitoring watches for performance degradation and data drift, triggering retraining when needed. This forms a continuous loop rather than a one-time delivery, keeping models reliable and aligned with current data throughout their operational life.

How does Appsierra support MLOps?

Appsierra's AI and data engineering pods help teams operationalize machine learning, building the pipelines, versioning, and monitoring that keep models reliable in production. We combine this with model evaluation practices from our AI governance work, so models are not just deployed but continuously validated. If your ML projects struggle to move from experiments to dependable production systems, we can help you put the MLOps foundations in place to deliver value safely and at scale.

Frequently asked questions

Is MLOps just DevOps for machine learning?

It builds on DevOps but goes further. MLOps adds practices for versioning data and models, tracking experiments, monitoring model accuracy, and retraining as data changes, addressing challenges that traditional software does not face.

What is model drift?

Model drift is the gradual decline in a model's accuracy as the real-world data it sees diverges from the data it was trained on. MLOps monitors for drift and triggers retraining to keep models accurate.

Why do many ML projects fail to reach production?

Without operational discipline, ML work often stays stuck in experimentation due to data, deployment, and maintenance challenges. MLOps provides the automation and structure needed to deploy and sustain models reliably.

What is versioning in MLOps?

Versioning tracks not just code but also data and models, so teams can reproduce results, understand what produced a given outcome, and roll back to known-good states when needed.

How does MLOps relate to AI governance?

MLOps focuses on reliable operation of models, while AI governance ensures they are used responsibly and evaluated for quality and risk. Together, monitoring and evaluation help keep deployed models both dependable and trustworthy.
