Moodle in cluster

Hey all !

I have a client, a big international group in hospitality. He want to have 2 Moodle servers to give some courses to 200-300 students (max in same time) distributed on few sites (2-99+ geographical sites). All sites are connected via VPN MPLS.

I want to know if you have any ressources or documentation about a Moodle clustering. He is so complicated about synchronization and usescases if the server 1 is down, the network is down on 1 site, the server 2 is down, the MPLS VPN is down on 1 geographical area etc.
The cluster in question is in Windows server and MariaDb (or MSSQL)

Thank you so much for your help !

Moving to Hardware and performance...

Clustering is relatively straightforward but I don't think I fully understand you. Are you talking about load balancing or failover?

Thesien,

Scalability in moodle using Windows server has already been discussed HERE, you can view that first to get idea of setting up a web farm on windows based servers.

You can handle 200-300 students simultaneously logged in on a single medium sized VPS. The Internet will look after the geographical sites. VPN, routing,.. are outside Moodle - the network comes before the server.

Almost forgot, I was talking about Linux, of course!

Well, you don't want your Moodle stack running on Windows Server. Linux is the way to go. Windows is an environment less supported and choosen here. We have Moodle running on Linux Redhat 7 and it's the most stable environment I've used for an application like Moodle.
Just a tip, for questions like scaling / clustering Moodle go to https://t.me/large_scale_moodle, very interesting to follow the discussions and questions there. You can also ask your own questions in the group.

I will double on Visvanath's recommendation, regarding security, hosted VPS's are hardened by hosting provider anyway, last thing they want is server holding VPS's going down getting a black spot on their reliability. even if every or most of security aspects are dealt with at your end, how would you cater the DDoS attacks? for that you need to have a beefy network supply and many hosting providers now include DDoS attack coverage for free in their packages,
