Imagine that you’ve undergone some kind of education – courses, university, training – whatever. 

In any case, you’ve obtained the essential knowledge you plan to apply in real life.

You invested your time and money, got a particular understanding of some niche, and …

Stayed unnoticed out there for some reason, with all your wisdom and unemployed.

Unfortunately, this often happens with ML models – 54% don’t go for production, as reports say. 

So, the bigger problem here is not to train a model – but to deploy it into the production workflow.

And here comes MLOps – an evolving discipline that combines the best practices from software engineering, data science, and DevOps to streamline the deployment and management of ML models in production. It serves as a bridge between ML research and the reality of deploying ML models at scale.

Still, the problem needs to be solved. According to a recent survey among 200 U.S.- based machine learning decision-makers, most respondents agree they fail to use ML to generate business and commercial value due to the difficulties of implementing it on a large scale.

In this article, we’ll tap a toe into the world of MLOps and shed light on its significance for organizations looking to harness the full potential of ML. We’ll explore the critical components of MLOps, its benefits to businesses, and practical steps for integrating MLOps into existing workflows.
