In this blog I will guide you on How to enable an application performance monitoring (APM). How to scale a user application based on application metrics with a Horizontal Pod Autoscaler (HPA). How to create an alert based on application metrics and send this alert to an external system. For the monitoring, I will use […]
Introduction When you are serious about running a microservice architecture at scale, you will definitely run into some challenges at some point. Beside all the benefits microservices deliver, they’ll also add a layer of complexity and have all the associated complexities of a distributed system.

If the COVID-19 epidemic taught us one lesson, then it is how dependent we are on data exchange over the internet. Just think back to yourself, how did you pass by 2020/2021? How did you exchange data with service providers or your employer? How did you entertain yourself while being under lock down or how […]
Introduction In this article series we are going to build together a sample cloud-native IoT architecture, called Bobbycar, based on the Red Hat OpenShift Container platform and a lot of other relevant technologies. The first part of the series should provide you with the necessary background on IoT-, Edge- and Cloud Computing and also briefly […]
