When starting this project I thought the same thing, but having done it I honestly cannot tell that much of a difference. Yes, there are two more steps in setting up the Lambda function, but in the end you still write an HTTP server and have them serve it.

Using a decent IaC framework such as Serverless Framework or the CDK instead of the AWS CLI would make the deployment pretty easy.

I also found while writing the article but after I had already done my research that cargo-lambda has grown some additional functionality that could have removed the need for the AWS CLI, but I wanted to get the article out, so I didn't test-drive that.

When using an EC2 instance, testing, deployment, and adding new endpoints are all simpler.

Easier for you* I've done both for years now and I find developing, deploying, testing lambdas much simpler.

I agree on testing and dev, but for deployment I think stuff like elastic beanstalk or app engine strike a good balance. Almost never run pure EC2.
