The site as of the first post was hosted on GCP using Cloud Storage, as per these instructions. This worked reasonably well and I was able to pick regions in such a way that for the small amounts of traffic I’m expecting, the cost was zero. The downsides of hosting via Cloud Storage were: No ability to add SSL certificates Setting up automation to push changes to the website was going to be an adventure The first of these problems is solvable by moving to Firestore.
