TileCDN
Contents |
What can we do to get a tile.openstreetmap.org contributable CDN within a month?
The basic outline;
- People seem to love using tile.openstreetmap.org for any of their apps
- Apps get blocked for various reasons, contributing back is difficult
- OpenStreetMap wants to be the leading provider of such data
I would propose a small working group to outline what should happen to
facilitate the creation of a Content Delivery Network (CDN) serving
the basic tiles, and allow easy contribution this network. This should
produce a prototype of at least 3 servers.
Questions such as: quality, update frequency, traffic shaping,
geographical balancing and high availability could be part of this
working group.
I would like to invite anyone to participate, especially:
- people that already have their own tileservers running, and/or are currently balancing traffic;
- business folks: what could be a motivation and what can be a cutback in for example attribution,
- users of for example openlayers, etc. what kind of caching can be applied, and if this should be configurable client side
Suggestions
Mike Dupont: archive.org is willing to host, ask for conditions. I followed up this suggestion, and emailed them.
Lynn W. Deffenbaugh: What about using Coralcdn.org?
Michal Migurski: Ask Amazon to donate Cloudfront services. Followed up this suggestion as well, waiting for a reply. I don't want to limit the question to Cloudfront only, because EC2 could give us a perfect way to actually create tiles.

Frequently asked questions
Will the usage of the CDN be free for end users? Yes
Archive.org
Archive.org is willing to host, given that we come with a plan for tilestorage and a schema. From their email;
We'd be happy to archive OpenStreetMap tiles on archive.org. It would be helpful to know in advance the approximate total size of all files and what mapping schema works for you. Since items on archive.org are best kept under 10GB total and less than 1000 total files per item it would be good to have a mapping scheme that makes the best use. Less Items with more files is better for us so maybe you do it by latlon or region. Let me know what you think is best and we can proceed. Each file would have a unique url that can be made permanent and archival regardless of how many files are in the item.
I've already replied, shown Tile Disk Usage. So I wonder if there is a best practise to tacle these constraints.
2012-01-24: Archive.org replied again. Still going forward, small scale test will be tried first.
