Have a look at https://www.serverlessmaps.com/ https://www.serverlessmaps.com/ which uses PMTiles to generate the tiles from OSM data. It's also possible to host the PMTiles directly on S3 and use HTTP range requests to retrieve the desired bounding boxes. Under the hood, it uses CloudFront as CDN, Lambda@Edge functions and S3 (see architecture at https://github.com/serverlessmaps/serverlessmaps/#architecture https://github.com/serverlessmaps/serverlessmaps/#architectu...) It's a very cost-effective solution as CloudFront has a 1TB/Month free tier, compared to hosted solutions.
