Becoming a “data trader”

Following its split from the New York Stock Exchange in 2014, Euronext became the first pan-European exchange in the eurozone, fusing together the stock markets of Amsterdam, Brussels, Dublin, Lisbon, and Paris. In 2016, Euronext began the typical process of migrating its data to the AWS cloud. Except that this migration had nothing typical about it at all. First off, the Euronext database contained 100 TB of data– one of the biggest in Europe.

Then there was the fact that this was not just a simple transfer of a database to a hosted platform. The idea was to create a governed data lake with self-service access for business units and clients in an effort to monetize new services and generate additional revenues.
