Comparing performances

Keeping systems and applications simple is always difficult, but often worth it for the business. Examples abound with overloaded UIs bringing down the user experience, while products with simple, elegant interfaces and minimal features enjoy widespread popularity. The Keep It Simple mantra is even more difficult to adhere to in a context such as predictive analytics where performance is key. This is the challenge Amazon took on with its Amazon ML service.

A typical predictive analytics project is a sequence of complex operations: getting the data, cleaning the data, selecting, optimizing and validating a model and finally making predictions. In the scripting approach, data scientists develop codebases using machine learning libraries such as the Python scikit-learn library or R packages to handle all these steps from data gathering to predictions in production. As a developer breaks down the necessary steps into modules for maintainability and testability, Amazon ML breaks down a predictive analytics project into different entities: datasource, model, evaluation and predictions. It's the simplicity of each of these steps that makes AWS so powerful to implement successful predictive analytics projects.
