Leaving aside (for now) the fact that AWS Lambda only supports .NET Core 1.0, would something like the Lambda support for ASP.NET Core Web API work for hosting Service Stack as a Lambda?
We've had reports of libraries client libraries like ServiceStack.Redis working in AWS Lambda after we've added some workarounds for missing .NET Standard API impls but I doubt the full ServiceStack Service is going to work without issues. From ServiceStack v5 we're moving to .NET Standard 2.0 / .NET Core 2.0 which isn't going to be supported on Lambda until they support .NET Standard 2.0.
For the record, PocoDynamo is working well within Lambda now that it supports .NET Standard 2.0. It's a very interesting combination.
Sweet, glad to hear it, thx for the feedback!
