Agile at Scale. Ever since we started our journey into Agile and scrum, we have been wondering whether we were on the right path for business and IT agility. Way back when we were with 7 scrum teams scaling wasn’t the most important issue. With our growth came challenges for scaling our agile way of working. We have been on a few plateaus where we were searching for the next step, as have been other companies on the same venture. Today we talk about some of the things we learned…

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…
