[Tilecache] Can TileCache store tiles remotely

Mon Jan 12 00:03:40 PST 2015

Hi David,

I'd personally use the nginx web server to proxy requests to the remote servers:
http://nginx.org/en/docs/http/ngx_http_proxy_module.html

Any webserver will do.

You can expand your server capacity proxing to other servers as your needs increase. The downside is that the proxy server becomes critical as it is the only path to get the tiles.

I'd group my TileCache services in logical groups, every group running on different server, and use the url in clients. Direct access is going to be faster, no need for a proxy, and no critical point. Of course it will all depend on your scenario, as you might not be able to change URLs on clients...

Hi Manel,

Thanks for your response. That's was I was thinking  to do. 

But I have one question... How do I proxy the requests?

Thanks again.

Agur bero bat,

Hi David,

I'd just run more instances of TileCache, on a different servers. It looks a lot simpler and you can always proxy the requests if you don't want to change urls on clients, either with TileCache or for example nginx.

You can even generate tiles beforehand and copy/move/rsync them to the remote server running TileCache. MBTiles is your friend :)

Hi Chris,

Thanks for your response. 

Why is that? I mean, does tilecache lock the directory in some way? 

What would be the best approach to have several tilecache instances reading/writing simultaneously?

Thanks in advance.

Network drive, sure. But be aware that a cache can only be used by one instance of TileCache... That is, you cannot have two or more instances reading and writing to the same set of tiles.

Hi list,

We're planning to change our architecture as our data is growing and I was wondering if tilecache can store the tiles in a remote server or network drive.

Thanks in advance.
