Fortunately, there is a solution in the form of Hadoop , an open source database that allows data and calculations to be spread across multiple computers. Hadoop is based on ideas published by Google in 2004. In 2006, this was picked up by a few people at Yahoo!, including Doug Cutting , who coined the name Hadoop. It is the name of his child's yellow stuffed elephant.
Speakers Friso van Vollenhoven from Xebia and later Reijer Klopman from Atos showed how you can use Hadoop. For example, Friso showed how Hadoop can be used to generate suggestions for the search bar of Bol.com and gave tips on how to get started: with a small team, second-hand computers (see photo) and one clear application, you can have a first application up and running within two weeks. Rob Dielemans from Xebia spoke in a later lecture about the end of classic business intelligence projects: thanks to cambodia telegram data Hadoop, systems are not only faster, but also easier to adapt. New reports can be created in days instead of months. According to him, Hadoop is now ready for use by all companies, because much better tooling has been developed that allows every Java programmer to start with Hadoop.
The weakness of Hadoop is that it is not built for transaction processing. However, solutions are being developed for this type of application.
According to the speakers, the great advantage of the cloud is its flexibility.
