Enhancing AWS Lambda Security with Deno
Using Deno with AWS Lambda functions requires a custom runtime. You can build your own runtime or use one that already exists. If you’re concerned about security, I suggest maintaining a copy of an existing runtime and carefully inspecting updates or creating your own runtime. For this proof of concept, I deployed the Serverless Application Repository (SAR) app for Deno into my AWS account. I used the included Lambda layer and the provided.al2 Lambda runtime to create my Deno Lambda function. I created a file called index.ts with some basic JavaScript code that makes requests to two different websites and returns the HTTP status code of the response or a caught error. I then updated the function’s configuration to reference the exported handler function.

Deploying to Lambda with the custom layer, but brand new to Deno - how do I cache the AWS SDK? Is there a version packaged with the custom layer?
I'm doing a simple PoC / testing with Deno using https://github.com/hayd/deno-lambda and specifically the CDK instructions.

Big Changes Ahead for Deno
As I had mentioned, it requires using a Lambda Layer. See: https://github.com/hayd/deno-lambda/blob/2d90756a0f18b57f16e...
Using your own image (i.e. without using the base AWS image with the layer) you'd get even worse cold start times.

First Look at Lambda Powertools TypeScript
Decorators and TypeScript aren't supported out of the box in Lambda (without using deno) so we'll also need a transpilation step if we go this route. Fortunately this is a mostly solved problem for AWS CDK, AWS SAM and Serverless Framework users. If you want or need to roll your own, esbuild is a great place to start and seems to be the bundler of choice for this purpose.

Is there an easy way to deploy Deno to production like for example Node to AWS Elastic Beanstalk? Or something in the works? I want to use deno in production on AWS Amazon.
In addition to the stuff posted here, there's the deno-lambda project for deploying to AWS Lambda

What is missing in Deno?
Cloud hosting support. Deno runs fine in a container, but lambda/cloud function support is difficult on most providers. deno-lambda exists but it only applies to AWS and can't be used with all CICD tools. Deno Deploy also exists but it's pretty new.

Deploying to Lambda with the custom layer, but brand new to Deno - how do I cache the AWS SDK? Is there a version packaged with the custom layer?
Ah yes I left comments about what I needed at the top of the Makefile here - https://github.com/Grunet/cfn-trace/blob/main/Makefile
