TL;DR for non-techies
This website costs about a pound a month to run. It’s hosted on Amazon’s cloud infrastructure, loads fast anywhere in the world, is secured to enterprise standards, and can be rebuilt from scratch in 10 minutes. Every part of it is automated - no manual steps, no clicking through dashboards, no room for human error. We built it this way because it’s exactly how we’d build cloud infrastructure for a client.
