AWS Lambda adds support for C#

Yesterday I blogged about Azure Functions and how the Visual Studio tooling can make your life easier. But the guys at Amazon are not sleeping and I noticed that they added support for C# as well.

Note that the AWS Lambda functions in C# are using the .NET Core 1.0 runtime. Similar to Microsoft, you get full tooling support thanks to the AWS Toolkit for Visual Studio.

  • Install the AWS Toolkit for Visual Studio.
  • Open Visual Studio and create a new project. Choose the AWS Lambda Project template and click OK.

  • Next step is to select a Blueprint.
    • We choose the Simple S3 Function blueprint.

  • You get a new project containing the following files
    • aws-lambda-tools-defaults.json: . This file contains default values that the blueprint has set to help prepopulate some of the fields in the deployment wizard.
    • Function.cs: Inside this cs file you can add your own logic.
    • project.json: this is the default project.json for .NET core applications(will be replaced by a csproj file in the near future)

  • The SDK is accompagnied by dotnet CLI integration. Open a command prompt and type dotnet lambda. Unfortunately I couldn’t find a way to debug locally.

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...
