One of the most amazing things I saw at AWS reInvent was an advanced talk on IaC that provided the code of a lambda function inline in a CloudFormation template. I realize that this is just one talk, and there are plenty of ways to structure things well, but this practice is directly encouraged by the design of CloudFormation[1]. AWS has attempted redefining the lambda deployment story multiple times, there are multiple companies whose primary offering is providing a better way to deploy code to serverless offerings, but this still stands out to me as one of the most terrible ways to do things, and I blame the design of CloudFormation.

I'm going off track here but Pulumi have a totally mind-bending feature where you can write the code of a lambda function not only inline, but such that it captures the value of variables from the surrounding infra code at the time the function is serialized. See: https://www.pulumi.com/docs/intro/concepts/function-serialization/ https://www.pulumi.com/docs/intro/concepts/function-serializ... Seeing the specific examples they use it for (AWS infra glue) makes me think that there is room for infrastructure related lambdas to be defined right in cfn or infra code, with very low ceremony, even if you wouldn't want to deploy "applications" like that.

  I'm working with what I think is a similar problem-space, trying to create a Node.js program that produces code to be run on the browser. The code runs in Node.js at "build time" which essentially means constructing the static web-site, which means some JavaScript must be somehow "deployed" to the website to be then later run at "run time". So deploying to an AWS etc. Lambda seems conceptually similar to deploying from static-site-generator to a static web-site source-code, which is then what the browser will execute. Or is it?
