What Does "MLOps (Machine Learning Operations)" Mean?
MLOps, short for Machine Learning Operations, refers to the set of practices, processes, and technologies used to manage the entire lifecycle of machine learning models.
In non-technical language, MLOps can be compared to managing the lifecycle of a product, from its development and testing to its deployment and ongoing maintenance.
Just as product operations ensure that a product is efficiently built, deployed, and maintained, MLOps focuses on streamlining and automating the processes involved in developing, deploying, and monitoring machine learning models.
Simple Analogies
To understand MLOps, let’s consider the process of baking a cake. Imagine you are a baker who wants to create a delicious cake. You start by gathering the necessary ingredients and following a recipe. This initial phase can be seen as the data gathering and model development stage of MLOps.
You collect and preprocess relevant data and train a machine learning model based on that data, similar to following a recipe to mix the ingredients and bake the cake.
Next, you need to ensure that your cake bakes correctly. You set the right temperature, monitor the oven, and keep checking on the cake’s progress. This can be compared to the deployment and monitoring stages of MLOps.
You deploy your trained model, monitor its performance, and make adjustments if necessary to ensure that it produces accurate and reliable results, just like keeping an eye on the cake and making sure it bakes evenly.
Once the cake is ready, you need to slice it and serve it to people. Similarly, in MLOps, you need to operationalize the model by integrating it into existing systems or applications so that it can be used by end-users. This is like serving the cake to the customers, making the results of the model available to the intended audience.
