Bringing some sanity to MicroServices

Bringing some sanity to MicroServices–Beyond the hype

Microservices, “SOA done right”, are the cool kids of the moment. Everyone wants to know them and sit next to them in the classroom. Everytime I see a customer just trying to copy the Netflix architecture or the Facebook architecture, it makes me cringe. Every architecture should be problem space first and technology/architecture second. Too many times people just start with a cool new architecture and then try to fit it inside their codebase, project and IT landscape. The new golden hammer makes everything look a nail…

So reading the blog posts of Christian Posta about Microservices was a relief for me. Finally some sanity in this crazy world. If you think that microservices fit your problem domain and you want to get some real insights, I recommend reading his blog series:

I hope that more posts will follow!

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t

DevToys–A swiss army knife for developers

As a developer there are a lot of small tasks you need to do as part of your coding, debugging and testing activities. DevToys is an offline windows app that tries to help you with these tasks.
