Create a hello world dotnet container, then do the same in a modern language. Then compare image size and resource consumption. Then imagine you're running tens of thousands of containers in a proper SaaS microservices model, and it'll make sense :)
Enterprise doesn’t spawn 10,000 containers to perform a simple “hello world” operation. That’s not how it operates. You’d be amazed at how many concurrent requests a single service can handle. This capacity must align with the actual requirements of the companies involved, not some unrealistic scenario like “we need to emulate Google.”
While that is small for a container and modern binary, I recall C hello worlds being 17KiB -- if only AOT/Spans/interop be used more to drive down those filesizes further.
Why? I routinely put compiled .NET programs into containers.
It's also easy (easier than Rust even) to build on Mac targeting a Linux image.
