Single node vs. multi node ML

Historically, the data scientists at Sierra Publishing have only trained their machine-learning models on their corporate laptops. As such, they have developed familiarity and processes with the single node machine learning frameworks but have needed help to get their models into production. They need help understanding the differences between single and multi node machine learning processes.

As the lead data scientist, you have done considerable research into Databricks and feel you understand the differences in these approaches.
