I actually have a few production workloads running exclusively on ARM servers and have saved money doing so. The applications themselves are in TypeScript, and Node as a runtime is cross arch without any extras. The hardest part is building docker images from my Github action. I wouldn't be surprised to find out that AWS is secretly switching the hardware running of their serverless overrings to use their in-house chips. Things like lambda (assuming source is distributed), aurora serverless, Dynamo, Cognito, CloudFront, etc

I don't believe this is much of a secret. A lot of internal services have been gradually shifted over the past couple years, there was a re:Invent talk this year about it.

Lambda has an ARM offering now. https://aws.amazon.com/blogs/aws/aws-lambda-functions-powered-by-aws-graviton2-processor-run-your-functions-on-arm-and-get-up-to-34-better-price-performance/ https://aws.amazon.com/blogs/aws/aws-lambda-functions-powere...
