I think the complexity for this setup is about the same. Once the different AWS services are provisioned during the initial setup, subsequent deploys are quite straightforward. For example, I have a three-line Makefile target for Jekyll sites that looks something like this (using Docker with a local `aws-cli` image wrapping the CLI):

    docker run --rm -e "JEKYLL_ENV=production" -v $(PWD)/src:/srv/jekyll -it jekyll/jekyll:3.8.5 jekyll build
    docker run --rm -itv $(HOME)/.aws:/root/.aws aws-cli aws s3 sync src/_site s3://www.<mydomain>
    docker run --rm -itv $(HOME)/.aws:/root/.aws aws-cli aws cloudfront create-invalidation --distribution-id <mydistribution> --paths "/*"
