View Full Version : Load balanced web servers
December 23rd, 2007, 12:30 PM
We are moving to load balanced web servers. There is no central storage, we are replicating everything from 1 master server out to the other web servers. Obviouly this is going to cause a large problem with photopost since it will want to store the images on the local drive. Does anyone have any idea how we can make this work?

The only way would be to keep that webserver path where photopost files are located always loaded and synced.

so if we configured bi-directional replication between the 3 servers on the photopost directory it should work?

If the photopost data directory can be accessed at all times and all files are correctly synced you should be fine but remember photopost uses one server path so that server path must always be running for files to be copied to and from it.

Ok so if I configured each server to use it's local path-
and there was bidirectional synchronization so each server had the identical files in that same directory
that would work except there might be a small delay while the synchronization software updates the directories.
The only problem I can see is a timing issue. What will happen if someone posts a new picture and then someone else goes to view the page if the database has updated but the synch software hasn't replicated yet
