Hi, we have a moodle platform based on Moodle 2.6 and hosted in Europe.
We need to extend access to chinese users and are therefore going to host the platform also in China (in a China based server).
However, we need to have full and efficient synchronization between the two platforms: we would like to manage them as one even if we will have two platform in two different servers.
Is there any already existing tools / script / software that enable us to do that?
Thank you very much.
It can't be done... no really, it can't.
Many have asked exactly this question or some variation on it. Moodle simply isn't designed to work in this kind of situation. I know of a couple of projects to do this and they all came to nothing.
The "Great Firewall of China" which is presumably making connections from China so bad that they need a local Moodle will also break just about anything else you try. I have seen the same issue many times now. Personally, I would leave them to their own internet misery but business is business. You just need to backup the courses send the backups to China (slowly) and restore them there. I'm not aware of an elegant answer.
use CDN speed up networks
or a mirror server
As a Chinese Moodler, I don't know why not have a Chinese Moodle Partner to do these work?
Marco, this can be done!
depending on what your server is based on in terms of operating system and web server, things will go different.
if you are Linux based - Apache with a hardware based layer 7 load-balancer serving clients on the basis of Geo Location, where you'll be keeping one server in China.
If on Windows based - IIS with ARR (Application request routing) and keeping one server in China (actually host with Singapore softlayer), and route traffic coming from china to singapore server. and that comes with Zero cost for the load balancing.
in both cases, ideally host database on google cloud/amazon cloud.
