I've got a piece of code that I need to make available over the 'Net. It's a perfect fit for an AWS Lambda with an HTTP API on top - a stateless, side effect free, rather CPU intensive function, blob in, blob out. It's written in C#/.NET, but it's not pure .NET, it makes use of the UWP API, therefore requires Windows Server 2016.

AWS Lambdas only run on Linux hosts, even C# ones. Is there any way to deploy this piece in the Amazon cloud in serverless manner - maybe something other than a Lambda? I know I can go with a EC2 VM, but this is the very kind of thing serverless architecture was invented for.

Lambda is the only option for serverless computing on AWS and Lambda functions run only on Linux machines.

If you need to run serverless functions in a Windows machine, try Azure Functions. That's the Lambda equivalent in the Microsoft cloud. I'm not sure if it runs in a Windows Server 2016 machine and couldn't find any reference to the platform, but I would expect that, as a brand new service, they are using their own edge tech.

To confirm if the platform is what you need, try this function:

using System.Management;
using System.Net;
using System.Threading.Tasks;    

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    // Get OS friendly name
    // http://stackoverflow.com/questions/577634/how-to-get-the-friendly-os-version-name
    var caption = (from x in new ManagementObjectSearcher("SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>()
                  select x.GetPropertyValue("Caption")).FirstOrDefault();
    string name = caption != null ? caption.ToString() : "Unknown";

    // the function response
    return req.CreateResponse(HttpStatusCode.OK, name);
}

I think yoy can achieve this via combination of CodeDeploy service and AWS CodePipeline.

Refer to this article:

http://docs.aws.amazon.com/codedeploy/latest/userguide/getting-started-windows.html

to learn how to deploy code via CodeDeploy. Later see this article:

http://docs.aws.amazon.com/codepipeline/latest/userguide/getting-started-4.html

to learn how you can configure aws Pipline to call Code Deploy and later execute your batch job on created windows machine (note: you will probably want to use S3 instead of Github - which is possible with CodePipeline).

I would consider to bootstrap whole such configuration via script - using aws cli - this way you can clean up easily your resources like this:

:aws codepipeline delete-pipeline --name "MyJob"

Of course you can configure the pipeline via aws web console and leave the pipeline configured to run your code on regular basis.
