Cloudflare worker
Wrote JavaScript
On my left, a terraformed multi-account HIPAA-compliant AWS infrastructure. On my right, a marketing team and some cool business domain names. To unite both sides, a little Javascript masterpiece running on Cloudflare workers routing requests at the edge. 

Super easy to setup, secure (proper SSL/TLS certs) and quick to update. (which is noteworthy considering there is a DNS involved ⏳)
