Lesson Descriptions 

Lesson 1: Introduction to Distributed Computing in Python
Lesson 1 starts with an introduction to the data science process and workflow. It then turns to a bit of history on why frameworks like Spark and Ray are necessary. Next comes a short primer on distributed systems theory. Python-based distributed computing frameworks come up next. Finally, Jonathan begins to explain the Spark ecosystem as well as how Spark compares to Ray.
Lesson 2: Scaling Data Processing with Spark
Lesson 2 goes into detail on the Spark framework beginning with a "Hello World" example of programming with Spark. Then Jonathan turns to the Spark APIs. You get some experience with one of Spark's primary data structures, the resilient distributed dataset (RDD). Next is key-value pairs and how Spark does operations on them similar to MapReduce. The lesson finishes up with a bit of Spark internals and the overall Spark application lifecycle.
Lesson 3: Exploratory Data Analysis with PySpark
In Lesson 3, Jonathan continues using Spark but now in the context of a larger data science workflow centered around natural language processing (NLP). He starts off with a general introduction to exploratory data analysis (EDA), followed by a quick tour of Jupyter notebooks. Next he discusses how to do EDA with Spark at scale, and then he shows you how to create statistics and data visualizations to summarize data sets. Finally, he tackles the NLP example, showing you how to transform a large corpus of text into numerical representation suitable for machine learning.
Lesson 4: Parallel Computing with Ray
Lesson 4 introduces the Ray programming API, with Jonathan comparing the similarities and differences between the Ray and Spark APIs. You learn how you can distribute functions with Ray, as well as how you can perform operations with distributed classes or objects with Ray actors. Finally, Jonathan finishes up with a large scale simulation to highlight the strengths of the Ray framework.
Lesson 5: Scaling AI Applications with Ray
Lesson 5 discusses how Ray enables you to scale up machine learning and artificial intelligence applications with Python. The lesson starts with the general model training and evaluation process in Python. Then it turns to how Ray enables you to scale both the evaluation and tuning of our models. You see how Ray makes possible very efficient hyperparameter tuning. You also see how, once you have a trained model, Ray can serve predictions from your machine learning model. Finally, the lesson finishes with an introduction to how Ray can enable you to both deploy machine learning models to production and monitor them once they are there.
