Euronext, the 1st European stock exchange with €3.7 trillion in market cap, built a governed data lake based on Amazon AWS to analyze data from one of the largest databases in Europe enriched with 1.5 billion new messages every day. Euronext uses Talend and AWS services - Amazon S3, Amazon Redshift and Amazon EMR for better agility, elasticity, breadth of functionality and cost savings, compared to the previous Netezza-based solution, while guaranteeing data governance and regulatory compliance.

Pay Only for the Resources You Use as you Scale
Lowest Cost
• Pay-as-you-go for the resources you consume
• As low as $0.05/GB scanned with Athena
• EMR and Athena can automatically scale down
resources after job completes, saving you costs
• Commit to a set term and save up to 75% with
Reserved Instance
• Run on spare compute capacity with EMR and save up
to 90% with Spot
Traditional approach leads to wasted capacity
