Protomaps is designed for simple CDN deployment, to turn your tilesets from these URLs:

https://s3.mycloudstorage.com/world.pmtiles

https://s3.mycloudstorage.com/world.pmtiles

To these URLs:

https://tiles.myglobalcdn.com/myvectordata/{z}/{x}/{y}.mvt
https://tiles.myglobalcdn.com/myrasterdata/{z}/{x}/{y}.png

https://tiles.myglobalcdn.com/myvectordata/{z}/{x}/{y}.mvt
https://tiles.myglobalcdn.com/myrasterdata/{z}/{x}/{y}.png

These installation guides should take less than one hour to deploy.

Advantages ​

• Serve tilesets to the web securely from private storage buckets.

• Cache tiles at the edge for the fastest response to users, taking advantage of global CDN presence. Single-region buckets can have multi-second latencies for users far away; CDN cache hits can respond in 100 millisconds or less.

• Backwards compatibility with existing map clients that use Z/X/Y map URLs.

• Affordable costs at scale. There are no servers to maintain for AWS and Cloudflare deployments, and you pay nothing if there's no traffic.

Components ​

A CDN deployment of Protomaps has three parts:

• The data: a storage bucket containing PMTiles archives.

• A serverless function that decodes incoming URLs into ranges and returns the tile bytes.

• A edge network that caches the responses from serverless functions.

Next steps ​

• Deploy PMTiles on Cloudflare.
• Deploy PMTiles on AWS.
• Deploy PMTiles with the Caddy web server.
