There are many reasons to run a big data distribution, such as Cloudera Data Hub (CDH) and Hortonworks Data Platform (HDP), in the cloud with Infrastructure-as-a-Service (IaaS). The main reason is agility. When the business needs to onboard a new use case, a data admin can bring on additional virtual infrastructure to their clusters in the cloud in minutes or hours. With an on-prem cluster, it may take weeks or months to add the infrastructure capacity for the new use cases.

2020 isn’t half done and society has already changed fundamentally. The COVID-19 pandemic has forced many people into unemployment because customers can’t visit their stores anymore.

In this article Julie Kent shows us how linear regression works, and walks through a practical example in Ruby.
