Cloud as Enabler to become more data driven. The adjective data driven means that progress in an activity is compelled by data, rather than by intuition, personal experience or a gut feeling. Googling data driven gives you over 637 mln. results so time to add an extra result to this with this episode. But we wanted to make it more specific. We moved or big data into the cloud and we had some nice insights that we want to share. We asked our two guests of this episode to do…

As long as retail exists, people tried to predict the future. An accurate forecast makes it much easier to buy the correct amount of products from suppliers, know what you need to keep on stock and even know what the sales will do with specific promotions. Over the last couple of years, this domain changed dramatically because of the introduction of Data Science and Artificial Intelligence. In this episode, we chat about this changing playing field to share our experiences with you. Guests Harmen Prins Erick Webbe Hosts Peter Brouwers…

Data Science and Machine Learning are becoming more integrated into current businesses. Especially in e-commerce there is huge potential for predictive modeling. It is therefore no surprise that bol.com has given extra focus on significantly expanding its Data Science efforts the coming year. That’s not to say that there aren’t already some interesting Data Science projects running. In this blog post we will take a look at one of the projects I am currently working on with fellow data scientist Joep Janssen: the chunk project.

At bol.com we service millions of products to millions of customers, resulting in billions of pages each year. We want to create the most effective service to our visitors we possibly can. So we spent a lot of time preparing the content, monitoring the systems and analyzing how we can support our customers better in finding what they really want.

On The NextBuild Conference I will host a talk about Designing scalable data intensive applications. At bol.com the datavolumes we need to process exceed the capacity of any single computer. As a consequence we are forced to think about designing our data intensive applications in such a way that they can be run on a cluster of systems and grow to handle much more that the volumes of today. In this talk I will show the main design concepts that bol.com has been using for more than 8 years that are needed to…
