NDC 2016–How to NOT do MicroServices

I’m currently at NDC Oslo following the Microservices with NServiceBus workshop by Jimmy Bogard. I got a lot of great insights and I’m impressed how NServiceBus helps you handle the complexity of a MicroServices architecture.

During the workshop Jimmy refered to the “Microservices: An application revolution powered by the cloud” article as an example on how to NOT do Microservices. Whoops! I don’t think that’s the way that Microsoft ment this article. Confused smile

Jimmy specifically refers to the way that the monolith application mentioned in the article is split out in multiple “micro”-services.

Breaking the monolith in microservices

As you can see in the image above, the microservices are oriented around technical concerns which is never a good idea when building a service architecture. Instead services should be oriented around business concerns and match your business processes.

He learned the hard way that the approach in the article didn’t work so don’t make the same mistakes.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. 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. Instead of using different websites you get a fully offline experience offering help for a large list of tasks. Many tools are available. Here is the current list: Converters JSON <> YAML Timestamp Number Base Cron Parser Encoders / Decoders HTML URL Base64 Text & Image GZip JWT Decoder Formatters JSON SQL XML Generators Hash (MD5, SHA1, SHA256, SHA512) UUID 1 and 4 Lorem Ipsum Checksum Text Escape / Unescape Inspector & Case Converter Regex Tester Text Comparer XML Validator Markdown Preview Graphic Color B
