If you are a data professional considering to upskill, there is no shortage of learning options, but if you are looking for ways to transition your data and analytics to the Cloud, you can choose between only a limited number of public Cloud providers.

The illustration above is an adaptation from PWC, one of the many Venn diagrams available on the internet attempting to explain the relationship between the terms, but it is not very straightforward.

Can we use data and analytical methods to capture the meaning and semantic context of these terms ? Ok, let’s give it a go and try to fight fire with fire. The Wikipedia clickstream dataset will be of great help for this. …
