2025 is the year when MLOps (Machine Learning Operations) has fully emerged from the shadows to take center stage. If AI is the engine, MLOps is the gearbox and oil that keep that engine running smoothly. This article dives into what MLOps is, why it’s a big deal in 2025, the top MLOps tools (from MLflow to Kubeflow to Vertex AI), the roles in the MLOps world, and how you can carve out a MLOps career path for yourself. Whether you’re new to the concept or looking to pivot into this field, you’ll get a roadmap for breaking into MLOps – a domain that’s part software engineering, part data science, and part DevOps. And yes, we’ll sprinkle Refonte Learning insights throughout to guide your journey.
What is MLOps and Why It Matters in 2025
MLOps is short for “Machine Learning Operations.” It’s a set of practices and tools that aim to deploy and maintain machine learning models in production reliably and efficiently. Think of it as DevOps (which revolutionized software deployment) but for ML models.
Why is MLOps crucial in 2025? Because companies have realized that building a good AI model is only half the battle – you also need to get that model into the hands of users and keep it working over time. Here are some eye-opening facts:
A famous Gartner study found that only ~53% of AI projects make it from prototype to production. In other words, nearly half of potentially great models never see the light of day due to deployment challenges.
Without MLOps, even a successful model can “die” in production if not monitored and maintained (data changes, software updates, etc., can break things). MLOps ensures models keep delivering value by automating retraining, monitoring performance, and handling the “plumbing” so data scientists can focus on building models.
As AI adoption has skyrocketed (74% of companies report struggling to scale AI beyond pilots), MLOps has moved from a “nice-to-have” to a must-have. In 2025, companies that invested in MLOps are reaping rewards in agility and reliability of their AI systems.
In plain language, MLOps is the secret sauce that turns one-off ML experiments into real-world, user-facing AI services. For example, imagine a predictive model that forecasts product demand for a retailer. Building the model is a data science task; deploying it to automatically update inventory systems daily is an MLOps task. Without MLOps, the model might remain an academic exercise. With MLOps, it becomes a business solution.
Refonte Learning has picked up on this trend, weaving MLOps best practices into its AI and data science programs. They know that to be truly job-ready in AI, you need some MLOps know-how.
Top MLOps Tools in 2025
The MLOps toolbox is rich and constantly evolving. Whether you’re managing experiments, orchestrating pipelines, or deploying models, there’s a tool for that. Here are some of the top MLOps tools and platforms in 2025:
MLflow: An open-source platform to manage the ML lifecycle (experiment tracking, reproducibility, model registry, etc.). Why it’s popular: It’s framework-agnostic, meaning you can use TensorFlow, PyTorch, scikit-learn – anything – and still track with MLflow. Many teams love its simplicity for recording metrics and packaging models. A typical use: log your experiments during model development and then register the best model for deployment.
Kubeflow: Think “Kubernetes for ML.” Kubeflow is an open-source toolkit that makes it easier to deploy ML workflows on Kubernetes. Why it’s popular: It helps manage complex pipelines in a scalable way. If you have data preprocessing, model training, and deployment steps, Kubeflow can orchestrate them across a cluster. In enterprise settings where Kubernetes is already used, Kubeflow integrates AI workloads into existing infra.
Google Cloud Vertex AI: A fully managed ML platform on Google Cloud. It offers everything from data labeling to training to deployment in one place. Why it’s popular: It abstracts a lot of the heavy lifting. You can train a model on cloud TPUs, deploy it as an API, monitor it – all within Vertex AI. It’s great if you’re on Google Cloud and want a one-stop-shop (AWS SageMaker and Azure ML are analogous on AWS and Azure clouds).
TensorFlow Extended (TFX): A Google-developed end-to-end platform for deploying production ML pipelines. Why it’s popular: If you’re into TensorFlow, TFX provides standardized components (like data validators, trainers, model servers) to go from research to production.
Airflow & Prefect: Workflow orchestration tools not specific to ML but widely used in MLOps to schedule and manage pipelines (e.g., retrain a model every night, or ingest new data daily).
Docker & Kubernetes: Not ML-specific, but foundational. Docker containers package your model and its environment, ensuring consistency from dev to prod. Kubernetes then manages those containers at scale. In 2025, most MLOps solutions use containers under the hood for deployment.
Other Mentions: Databricks MLflow (often used within the Databricks environment), DVC (Data Version Control) for tracking data and model files, Seldon or BentoML for model serving,(experiment tracking platform that in 2025 published a comprehensive MLOps landscape covering 90+ tools!). The landscape is huge, but you don’t need to learn all at once. Focus on one from each category: e.g., MLflow for tracking, Kubeflow or Airflow for pipelines, Docker/K8s for deployment, and maybe a cloud platform like Vertex AI.
Refonte Learning often introduces students to these tools in hands-on projects – like using MLflow to track a computer vision model training, then deploying the model with Docker on a cloud service.
MLOps Roles and Responsibilities (ML Engineer vs DevOps vs Data Engineer)
In a team that’s building AI products, who does what? MLOps has given rise to specialized roles, but there’s often overlap with existing ones. Let’s break down key roles:
MLOps Engineer / ML Engineer: This is the person primarily responsible for the end-to-end ML pipeline in production. They take models from data scientists and ensure they’re properly packaged, tested, deployed, and monitored. Day-to-day, an MLOps Engineer might set up CI/CD pipelines for ML (automating the training and deployment process), configure cloud resources, write scripts to retrain models, and build dashboards for monitoring model performance (accuracy, latency, etc.). They need a mix of software engineering, cloud architecture, and understanding of ML. Refonte Learning notes that this role is often filled by someone who started as a software or DevOps engineer and learned ML, or a data scientist who learned devops skills.
DevOps Engineer (with ML focus): A traditional DevOps engineer works on CI/CD, infrastructure, automation – ensuring software (now including ML models) moves smoothly from development to production. When it comes to machine learning projects, a DevOps engineer’s role overlaps with MLOps. They provide the tools and environment (CI/CD pipelines, servers, storage, etc.) needed for ML models to be deployed. They might not tweak model hyperparameters, but they might containerize the model and set up the automated deployment triggers (like “when a new model is registered, automatically deploy it to staging”). In smaller teams, a DevOps engineer often becomes the de-facto MLOps person.
Data Engineer: In the context of MLOps, data engineers handle the upstream part – making sure the data pipelines that feed the models are working. They build systems to collect, clean, and store data for training and inference. If a model is retrained weekly on fresh data, the data engineer ensures that data is ready. They may also optimize databases or data processing jobs so that the ML pipeline has quick access to what it needs. While not “deploying models,” they collaborate closely – if a model prediction pipeline is slow, a data engineer might help speed up the data retrieval part.
Data Scientist/ML Researcher: They are typically the ones developing the model (research, prototyping, training experiments). In an MLOps team, once they have a model that meets certain metrics, they hand it off to the ML Engineer or MLOps system to deploy. However, data scientists remain involved to verify the model’s performance in production, respond to issues (like if model accuracy drifts, they might retrain or adjust it), and sometimes even help with monitoring. There’s a growing expectation that data scientists know the basics of MLOps so they can collaborate better. Many Refonte Learning data science courses now include a module on “deploying your model” for this reason.
ML Architect: This is a more senior role where one designs the overall system and workflow for how models go from dev to prod. The ML Architect might decide “We’ll use Kubeflow for pipeline orchestration, use AWS for hosting the model endpoints, set up an alerting system for model drift, and ensure compliance/security of the ML pipeline.” They create blueprints and guide MLOps engineers and DevOps in building it out. Think of them as the high-level planner ensuring the MLOps process aligns with business needs and technical constraints.
Software Engineer: Traditional software engineers also play a part. They often work on integrating the ML model into the broader application (writing the code that calls the model’s API and puts results into the app). They ensure the final product (say a web service with AI features) is user-friendly, stable, and maintainable. In some teams, software engineers and MLOps engineers collaborate or roles may merge if one person does both.
In a nutshell, MLOps is a team sport. Small companies might roll all these into one or two people; large enterprises might have separate teams. Knowing how these roles collaborate will help you position yourself. If you’re more of a coder who loves infrastructure, aim for MLOps/DevOps roles. If you love data pipelines, data engineering is a route. If you straddle both, ML Engineer is a fit. Refonte Learning career counselors often advise students on which role suits their background – e.g., a student with cloud computing experience might target MLOps Engineer positions, whereas one with database skills might lean Data Engineer.
Career Trajectory: How to Get Started and What to Learn (MLOps Roadmap)
Breaking into MLOps can seem daunting because it spans multiple domains. Here’s a step-by-step MLOps career roadmap to get you from newbie to pro:
Learn the Basics of Machine Learning: You don’t have to be an ML expert, but you need to understand how models are built and what the workflow looks like. Take a beginner course in ML (if you haven’t already). Refonte Learning has an “AI & Data Science foundations” course that covers training a simple model. Key concepts: training vs inference, common algorithms, evaluation metrics.
Get Comfortable with DevOps Fundamentals: Learn about containers (Docker) and container orchestration (Kubernetes). Try deploying a simple web app via Docker just to grasp the idea. Learn basics of CI/CD – maybe set up a GitHub Actions pipeline to run tests on code commit. You don’t need to be a DevOps guru off the bat, but you should know why automation is useful.
Learn a Programming Language Well (Python is a Must): Python is the lingua franca of ML and MLOps. Also, learn some Bash/shell scripting since automation often involves shell commands. If you’re coming from software engineering, this might be easy. If from data, focus on writing clean, production-quality Python code (not just Jupyter notebooks).
Pick Key MLOps Tools to Practice: Don’t try to learn all at once. A good combo to start: MLflow for experiment tracking (easy to set up locally), Docker for packaging models, and maybe a cloud service like AWS SageMaker or Google Vertex AI for deployment (they have free tiers or trial credits). For example, train a simple model and use MLflow to record it, then create a Docker image that serves predictions from that model via a Flask API. Deploy that Docker container on a cloud instance or use a service like Heroku. This project touches many aspects: model, tracking, serving, cloud.
Understand Data Pipelines: Work with a tool like Apache Airflow or even simple cron jobs to automate a task (like retraining a model weekly). If you can, explore Kubeflow Pipelines or Prefect to see how ML tasks can be strung together. Refonte Learning often has students implement a mini-pipeline as a capstone (e.g., daily data ingestion + weekly model retrain + monitoring).
Version Control Everything: Get used to Git for code, and look into DVC (Data Version Control) for managing dataset and model versioning. Employers love when you’re organized – e.g., you can demonstrate how you tracked dataset versions that correspond to your models.
Hands-on Projects / Internship: Build a portfolio showing you can do MLOps. Maybe contribute to an open-source MLOps tool on GitHub, or do a small project like “Create a sentiment analysis model and deploy it with CI/CD”. Internships are golden – something like Refonte Learning’s internship where you work on real projects will provide concrete experience.
Advanced Concepts: As you progress, delve into monitoring tools (like Prometheus, Grafana for monitoring system metrics, or bespoke ML monitoring for data drift). Learn about “feature stores” (tools for serving ML input data consistently for training and inference). Security is another – e.g., how to handle sensitive data in ML pipelines. But these can come once you have the core skills down.
Career Progression: You might start in a mixed role (like “Software Engineer with ML emphasis” or “Jr. Data Engineer”) and then pivot into a dedicated MLOps role as you prove your skills. Many MLOps engineers in 2025 started as something else 2-3 years ago (because MLOps itself wasn’t a big field until recently). With a solid foundation, you can rise to senior MLOps engineer, lead teams, or become an ML Architect in charge of big-picture ML systems. Companies like Google, Netflix, and emerging startups are hungry for this skillset. Refonte Learning reports that the hiring rate for their graduates with MLOps skills has grown sharply.
Analogy / Story: Consider MLOps like running a bakery. The Data Scientists are the chefs creating new recipes (model ideas). But without a good kitchen setup and operations (the ovens, the process to consistently bake every morning, quality control to ensure each loaf is good), those recipes might never scale to feeding customers. The MLOps Engineer is the master baker who set ups the kitchen, automates the mixing and baking process, checks that each batch tastes right, and scales output as demand grows. In 2025, a lot of AI projects have great “recipes” but need that operations excellence to serve thousands of customers consistently – hence the rise of MLOps roles.
Actionable Steps to Break into MLOps
Master Python & Linux: Ensure you can comfortably write Python scripts and navigate the command line.
Containerize a Model: Take a simple ML model, put it behind a REST API (using Flask/FastAPI), and dockerize it. This exercise teaches deployment fundamentals.
Use an MLOps Pipeline Tool: Try Kubeflow, MLflow, or Airflow on a small project. Even if it’s local, set up an automated training + deployment pipeline.
Learn Cloud Basics: Get familiar with one cloud platform (AWS, GCP, or Azure). Learn how to deploy a container and use a managed ML service.
Study Real-world MLOps Case Studies: Read blogs or watch talks on how companies productionize ML (many share their tech stack). This gives context and talking points for interviews.
Certifications (Optional): Certifications like AWS Machine Learning Specialty or Google’s Professional ML Engineer can signal your knowledge. Refonte Learning offers prep courses for some of these.
Contribute to Open Source: If possible, contribute to a project like MLflow or KubeFlow docs/code. It’s a great way to deepen your understanding and show initiative.
Network and Join Communities: Engage in MLOps communities (there are MLOps-specific groups, meetups, and Slack channels). Networking can lead to job referrals and keeps you updated on trends.
By following these steps, you can transition into an MLOps role or start one from scratch.

FAQs About MLOps Careers
1. What is MLOps and is it a good career path?
MLOps stands for Machine Learning Operations. It’s a set of practices and roles focused on deploying, monitoring, and maintaining ML models in production. In simpler terms, it’s like DevOps but specifically for AI/ML projects. It’s a great career path if you enjoy both software engineering and machine learning. In 2025, companies are heavily investing in MLOps because many have struggled to turn AI prototypes into actual products. As a result, skilled MLOps engineers are in high demand and can command high salaries. It’s a good career if you want to be at the intersection of coding, data, and cutting-edge AI applications.
2. Which MLOps tools should I learn first?
A good starting point is to learn MLflow for experiment tracking, since it’s simple and widely used. Next, understand Docker (for containerizing ML models) and a bit of Kubernetes (since many MLOps tools run on it). For orchestration, Apache Airflow is common and relatively friendly to learn. If you want to dive deeper, try Kubeflow to see how complex ML pipelines can run on Kubernetes. Also, familiarize yourself with a cloud platform’s ML services, like AWS SageMaker or Google Vertex AI, since many companies use these tools. Remember, you don’t need to master all tools at once. Start with one from each category: tracking (MLflow), deployment (Docker), orchestration (Airflow or Kubeflow), and you’ll build a strong foundation.
3. Do I need to be a data scientist to work in MLOps?
No, you don’t have to be a data scientist, but you should understand the basics of machine learning. Many MLOps professionals come from a software engineering or DevOps background. They learn enough ML to understand what needs to be deployed and how to evaluate if a model is performing well. On the flip side, some data scientists transition into MLOps by picking up software and cloud skills. The key is being comfortable with both worlds: you should know how models are trained and how software systems are built. If you’re a data scientist, start learning about cloud services, containers, and CI/CD. If you’re an engineer, start learning about the ML lifecycle and model evaluation. Resources like Refonte Learning’s courses can help bridge whichever knowledge gap you have.
4. What are the typical responsibilities of an MLOps engineer?
An MLOps engineer is responsible for getting ML models from the development environment (where data scientists build them) to the production environment (where end-users or systems use them) in a robust way. This includes setting up infrastructure to deploy models (often using cloud services or Kubernetes), building automated pipelines for model training and deployment (CI/CD for ML), monitoring models in production (tracking performance, data drift, etc.), and managing resources (like scaling up GPU servers when needed). They also handle versioning of models and data, ensuring reproducibility. Essentially, MLOps engineers make sure AI doesn’t just work in the lab but continues to work reliably in the real world. It’s a mix of coding, system design, and problem-solving when issues arise.
5. How do I start a career in MLOps?
Start by building a foundation in both machine learning and DevOps. Begin with learning Python and basic ML libraries (like scikit-learn) to understand how models are created. At the same time, learn how to use Docker to containerize applications. Once you have these basics, try a simple project — for example, train a model and deploy it as a web service using Flask and Docker. This will expose you to many aspects of MLOps (model, code, container, service). From there, learn an orchestration tool like Airflow to automate workflows. Get familiar with cloud platforms — many offer free tiers (e.g., deploy a simple model on Heroku or AWS). Also, explore specialized courses or certifications; Refonte Learning and other providers offer structured MLOps programs. Contributing to open-source MLOps projects or writing about your learning journey can also boost your visibility. The key is hands-on practice — with each project, try to incorporate more of the MLOps toolchain. Over time, you’ll build the skills needed to land an MLOps engineer role.
6. Is MLOps a fad or here to stay?
MLOps is here to stay. A few years ago, some might have seen it as just a buzzword, but by 2025, it’s clear that MLOps fills a critical gap. Companies have invested heavily in AI, and they realized that without proper operations, those investments don’t translate into value. MLOps has grown out of real needs — like monitoring model performance continuously, handling data pipeline changes, and retraining models when needed. It’s similar to how DevOps became indispensable for software development. As long as organizations continue to deploy machine learning (which is only increasing), the practices of MLOps will remain in demand. Even if the term “MLOps” eventually fades, the skill set — combining ML knowledge with operational expertise — will stay highly valuable for the foreseeable future.
