In this blog, we show you how to automatically scale your application resources according to either the CPU consumption or to the incoming load of your application.  Background As humans, we are capable of adapting to variable inputs and situations. Some of us are slower, whereas others easily adapt to change. In dynamic environments, flexibility has become one of the most valued skills. As engineers, we also thrive for adaptability. We embrace new technologies, new responsibilities, and new ways of working together. We want to build future proof solutions that react quickly…

Introduction At bol.com we have two main ways of running our applications. We can deploy them in a Datacenter (DC) managed by us or we can run them on Google Cloud Platform (GCP). Many applications are being migrated from DC to the GCP to take advantage of the different products available in GCP. Switching to the cloud isn’t just a matter of lift ‘n shifting your application though, there are several changes that you should take into account. One of those changes is, how the behavior of the underlying platform…

How we tame Google Cloud resources with R2D2. We had some episodes on the cloud already. Now it’s time to discuss how bol.com combines the promises of the cloud and their requirements for Reproducibility and Reliability. For instance, balance infinite resources and ultimate autonomy with security. Within bol.com we developed R2D2. R2D2 stands for our Reproducible Resource Deployment Definition tool which combines the functions of Terraform, Cloud SDK and Puppet Labs. It helps us to ensure Recovery, Security, Self-service, Stability and Scalability in our move to the cloud. The reason…

Redesign for the cloud – horizontal scaling

Peter Paul van de Beek, Peter Brouwers, on 26-09-2019
Category: Podcast Tags: Architecture Scalability cloud Podcast redesign

We think “the Cloud” is to broad a subject to handle in one episode of the podcast. That is why we break down our cloud journey in small pieces and go over them in separate episodes. This time we dive into “Redesign for the cloud – horizontal scaling”. In an earlier episode we discussed how we moved our Big Data to the Cloud, in the Cloud as an enabler to becoming more data-driven. When moving applications and services to the Cloud we think about redesigning them, like in this case…

We moved our big data into the cloud and we got some nice insights that we wanted to share. We asked our two guests of this episode to do so. It turned…
