What is MLOps and why is it important?

Machine learning (ML) has been a buzzword going around the tech industry for quite some time. And yet, though everybody knows of it, companies fail to implement it, or ML doesn’t bring the promise of delivering (financial) business value.
It takes an organization quite some time to create productional algorithms effectively. The main reason for failure is the gap between creating machine learning models and applying the models to business processes systematically.
To help solve this, I will explain how MLOps can be implemented to deliver better business results for a prolonged time.
What is MLOps
ML can be a game-changer for a business, but it can evolve into a science experiment without systemization. The real challenge isn't building an ML model; the challenge is building an integrated ML system and continuing operating it in production.
MLOps is a practice for collaboration and communication between data scientists and operations professionals to help manage the production ML lifecycle. It is an ML engineering culture and practice that aims at unifying ML system development (Dev) and ML system operation (Ops).
The diagram below shows that only a tiny fraction of a real-world ML system is composed of ML code. The surrounding elements are vast and complex, requiring a team of Data Scientists, developers, and operations professionals to work together effectively and systematically.

Why is MLOps important
MLOps brings business interest back to the forefront of ML operations. Data scientists work with the business interests and goals, with clear direction and measurable benchmarks.
MLOps follows a similar pattern and principles to DevOps and DataOps. The practices that drive integration between the development cycle and the overall operations process can also transform how the business handles data. Like DevOps shortens production life cycles by creating better products with each iteration, MLOps drives insights you can trust and put into play more quickly in a controlled manner.
ML is mighty: it’s a process that generalizes from data examples. It provides the ability to understand or value something/someone relatively new to you. But ML itself is a means to an end. The business value will make the difference in what you do with that understanding/value. If it fits your business's strategy, you should use MLOps to achieve this. Some examples we operate at Crystalloids:
Measures like Return on Ad Spend (ROAS) and Profit on Ad Spend (POAS) allow you to optimize spending your money on visitors that are likely to convert and not target ones less likely to convert.
How do you identify which customers are very likely to convert? Try to exploit the behavioral patterns that precede conversion by using predictive modeling. The past behavior of visitors, combined with their conversion information, can be applied to future visitors. For example, it could be that customers who recently visited the website with many recurring page views are much more likely to buy something in the coming 15 days. To improve that likelihood even further, targeting them with ads can prove a good investment for just that kind of visitor.
2. Predict visitor engagement and use it for a campaign or channel optimization.
For example, by landing page differentiation on geographical region, showing those products that best fit the regional interests, taste, and culture. Another example of visitor engagement differentiation is identifying and predicting channel preference or communication timing. The latter can make a massive difference in the usage of social media.
3. Predict product popularity and use it for product placements.
Product recommendations are a well-established technique to personalize a web page, app, or email. By using customer attributes, browsing behavior, or situational context, one can recommend products that are perceived as relevant. Companies like Spotify and Netflix mainly exist because they can operate recommendations effectively.
How it works
Practicing MLOps means that you advocate for automation and monitoring at all steps of ML system construction, including integration, testing, releasing, deployment, and infrastructure management.
The steps include:
- a data pipeline providing up-to-date validated, and preprocessed data (Feature Store)
- a development environment to experiment with building models
- a training pipeline that allows you to create ML models from the data
- a continuous training pipeline that automates constructed training pipelines
- a model deployment process that will enable you to take your (chosen) model to production
- a model performance monitoring process that (automatically) checks if model performance is still excellent or decaying.
Where to start
It doesn’t start with data or technology. It does begin with a business plan of how to monetize a generalizing model by defining the use cases that serve the strategy.
Next, you need a multidisciplinary team. The team usually includes data scientists or ML researchers, who focus on exploratory data analysis, model development, and experimentation. They build a training pipeline delivering models, test them and try to convince the business of their added value. Next, experienced software engineers must construct production-class services that deploy models, monitor model performance, and automatically retrain them. Finally, operations professionals should take responsibility for monitoring the overall MLOps continuity.
