What Is MLOps and How to Leverage It for Your Machine Learning Projects
Did you know that 80% of models trained and developed never make it to production? One of the main reasons for this is the lack of collaboration and communication among parties involved in the various stages of an AI-related project. As machine learning products become integral components in various business operations, business owners realize the need for a systematic and automated approach to implementing and supporting machine learning (ML) models. Consequently, they begin to seek solutions. Many DevOps practices come in handy, but ML projects still require an approach tailored specifically to ML. That is why Many businesses are turning to the MLOps process — but what is MLOps, and how can it bridge the gap between machine learning and production?
As an AI-focused software development team, we at Flyaps have more than a decade of fish-hand experience with machine learning projects like UrbanSim and CV Compiler. In this article, we will talk about MLOps meaning for businesses and how it will grow models’ chances of reaching production. Moreover, we will cover a few successful MLOps use cases and share some best practices for MLOps implementation. But before that, a quick definition.
The machine learning operations (MLOps) definition
Machine learning operations (MLOps) is a methodology designed to automate and streamline workflows and deployments in machine learning projects. MLOps allows to integrate ML application development with system deployment and operations, creating a cohesive approach for managing the machine learning lifecycle.
Imagine a company that specializes in developing machine learning models for personalized recommendation systems. Without MLOps practices in place, their development process is fragmented and time-consuming.
Before adopting MLOps, the company’s data scientists had to manually develop machine learning models, using different tools and libraries per each. This approach led to inconsistencies and duplication of efforts.
Testing was also done irregularly, often leading to missed bugs and errors that were only discovered in production. Integrating a trained and validated model into an existing system required manual intervention, resulting in delays and potential compatibility issues. As the infrastructure for model training and inference was handled separately by the IT team, the outcome was numerous inefficiencies and resource wastage.
After implementing MLOps practices, the data science teams started collaborating using standardized tools and workflows, enabling them to develop and iterate on newly trained models efficiently.
MLOps also allowed to automate three crucial parts of the company’s ML project:
- Testing frameworks to reduce the risk of errors in production.
- Integration of models into production systems to streamline the deployment process.
- Infrastructure provisioning and infrastructure management to optimize resource usage and scalability.
The result? The company now has more streamlined model development and deployment processes and enhanced reliability with automated testing and deployment practices. The ML infrastructure can handle growing data volumes and user demands, which positively contributes to scalability.
MLOps vs DevOps
You can notice some similarities between MLOps and DevOps. But there is a big difference between them, which lies in focus and application.
MLOps is specifically tailored to ML projects and focuses on managing the lifecycle of ML models. DevOps, on the other hand, is a broader approach that primarily focuses on software development and IT operations. It emphasizes collaboration, automation, and integration between software development and IT operations teams to deliver high-quality software efficiently.
MLOps process applies DevOps principles and practices to the unique challenges of machine learning projects. It involves automating and standardizing ML workflows, implementing continuous integration and deployment (CI/CD) pipelines for ML models, and ensuring scalability, reliability, and performance of ML systems in production. DevOps, on the other hand, is applied across the entire software development lifecycle, from code development and testing to deployment and maintenance.

6 steps of the MLOps process
As we’ve already mentioned the machine learning lifecycle a few times, let’s dive into this topic a bit deeper and discover what stages exactly you’ll need to go through when implementing machine learning in operations, with some best practices to follow.
1. Data preparation
Data preparation is critical to the success of your machine learning models. It's about getting your data in shape so your model can learn from it effectively. This includes data collection, as well as cleaning and transforming the data to make it suitable for model training.
Best practices for data preparation
- Ensure data quality
It's important to make sure your data is clean and error-free. Get rid of any errors, odd values, or missing parts. Use techniques such as data validation and quality checks to get the best result.
- Feature engineering
Engage in exploratory data analysis to identify and create the most relevant features for your trained model. Effective feature engineering improves model performance and ensures that the model effectively addresses the problem at hand.
- Data versioning
Just like keeping track of different versions of a document, it's important to keep track of changes to your data. This helps ensure that you can go back to a specific version when needed and maintain consistency. Tools like Git or DVC (Data Version Control) are great for managing and tracking different versions of your data, enhancing collaboration within data science teams.
2. Model training
Once data is all set, it's time to train machine learning models. The model training process is quite similar to teaching a computer to learn from the prepared data. This involves picking the right algorithm or method, giving it the prepared data, and tweaking it to perform its best. You might use techniques like cross-validation, hyperparameter tuning, and ensemble methods to make sure your model is accurate and works well for different situations. The goal here is to create a model that can effectively solve the intended problem.
Best practices for model training
- Experiment tracking
To keep track of all your experiments, including the settings and performance of each one, you can use helpful tools like MLflow or Neptune. This ensures that all aspects of the experiment cycle are documented.
- Hyperparameter tuning
Hyperparameters can be thought of as knobs and dials that can be adjusted to improve your model's performance. To improve your model's performance, try testing different combinations of settings using techniques like grid search, random search, or Bayesian optimization.
- Cross-validation
Cross-validation evaluates how well your model understands the material, ensuring it can generalize to new data effectively. This is crucial for avoiding overfitting and validating the model prediction service.
3. Model evaluation
Model evaluation is the process of determining how well models perform. After training your model, you must test it to assess its effectiveness. This involves examining various metrics, such as accuracy, precision, recall, or area under the curve (AUC), depending on your objectives. Additionally, you must evaluate how well your model performs on new, unseen data by testing it on separate validation or test datasets. This evaluation process ensures that only the most reliable and accurate models proceed to the next stage.
Best practices for model evaluation
- Select appropriate evaluation metrics that align with your specific problem and goals
Common metrics include accuracy, precision, recall, F1 score, or AUC. These metrics aid in comprehending the performance of your model across various aspects.
- Employ multiple evaluation strategies to ensure consistent performance
- Evaluate your model on separate validation and test datasets to avoid bias and overfitting, where the model is too tailored to the training data
4. Deployment
Deployment is the stage where trained models are put into use in the real world. Here, you can make your models available for live environments to make predictions or provide insights. It's important to consider factors such as the number of users your model will have, its response time, and the resources it will require to perform well. There are various ways to deploy models, including batch data processing or real-time interfaces.
Best practices for deployment
- Containerization
Considered containerization as a way to package your model and its dependencies for consistent deployment across various environments, and tools like Docker can help with this process.
- Automated deployment
Imagine setting up a conveyor belt that automatically transports your model from development to deployment. Tools like Kubernetes or serverless platforms can help you create automated deployment pipelines, making the process smoother while reducing the likelihood of errors.
- Version control
It's also important to monitor modifications to your model and deployment setup. You can use version control systems like Git to keep a record of all aspects, including your model versions and deployment configurations.
5. Monitoring and maintenance
Once your models are up and running, it's crucial to keep an eye on them to ensure they're performing well, reliable, and meet business goals. Monitoring means keeping track of different measures like accuracy, response times, and any changes in data patterns. This helps catch any problems early on. You can also set up alerts to notify you if models work improperly. Regular maintenance is key too – this includes things like updating your models with fresh data and fine-tuning them to keep them working their best.
Best practices for monitoring and maintenance
- Set up monitoring infrastructure
Use tools like Prometheus and ELK stack, or create custom scripts to track how your models are doing, spot any changes in data patterns, and see how resources are being used.
- Establish alerting mechanisms
Define thresholds for what's considered normal performance and set up alerts to notify you if anything goes wrong. This could be through email, Slack, or SMS.
- Scheduled retraining
Decide how often your models need updating based on how quickly your data changes and how well your models are performing. Regularly updating your models with fresh data helps them stay accurate and relevant.
6. Retiring and replacing models
Models may become outdated or less effective over time due to changes in data patterns, business requirements, or technology advancements. The retiring and replacing mean assessing the need to retire existing models and introducing newer, more improved models. It requires careful planning and execution to ensure a seamless transition from the old model to the new one while minimizing disruptions in production environments.
Best practices for retiring and replacing models
- Incremental deployment
Plan for a gradual transition by deploying and testing new models alongside existing ones before fully replacing them. This helps minimize disruptions and ensures a seamless transition.
- Document and communicate
Document the reasons for retiring or replacing models and communicate these changes to stakeholders. Provide clear instructions on the transition process and any updates needed for downstream systems.
