One year later, we choosed Moodle after 6 years with WebCT. It was just for one server with less than 500 users, some students in 7 universities of law.
Then, we opened another server for the 17.500 students of the Toulouse (south of France) University of Law. Following your instructions, we choosed a bi-xeon, 3.2 Ghz, 4 Go RAM for about 150 simultaneous users. It works very well ... thanks for all.
The experience was so interesting that the UNJF (French language University of Law) choosed our solution with our technical team. But the problem is the potentiality of 200 000 students, and, perhaps 500 simultaneous users, with courses mainly composed with text.
Could anyone help us choose the number of servers (application/database/charge repartitor, ...) for up to 50.000, 100.000 and 200.000 users, and help us to configure it (php accelerator, lite-httpd, ...).
We may be next year one of the most important institutions using Moodle in the world ... so the challenge is interesting, but risks are very important.
Thanks for all answers.
Lighttpd could be a good idea - but: apache is known to be very stable . So I would prefer apache for your project. Manpower is much more expensive then hardware. Lighttpd could give you a performance boost by 20%, but excellent hardware does it, too.
Good luck, that is a big thing...
Thanks for your answers,
We thought to buy a Blade ... with an andefined number of Lame Servers.
And the question is the number of servers (bi-dualcore) that we need to start with perhaps 50.000 to 100.000 users in january 2007 and until 500 simultaneous users. We are not sufficiently "aware" to imagine the configuration of each server too (Power in Ghz, 1,2,4,8 Go RAM ? Disk capacity of each one).
We think that we may buy a SAN too, for database and file storage.
Will one server be sufficient for database ?
May we use one server for firewall and load balancing or 2 servers for redondancy ?
How are defined secure configurations for such a number of users ?
This questions are not very easy to post, and not really easy to answer i think.
But if someone in the community could give some information to help us, like you did, it would be very interesting before we publish an "offer-call" for french societies.
If we know approximatively the configuration and money we must put in this work, it would be easier for us to get money for the project. But we cannot call a society like Catalyst in NZ if we don't work with it after.
Thanks too for the comparison between lighttpd and apache. Apache seems more stable ... and perhaps will be the solution for our system. If postgres seems better than my, it can be the solution we'll use too.
My name is Daphne De,etriades and I am from Cyprus and I work for a company which developes and supports e-elarning.
We ar enow bidding for a very big project for the Cyprus Governemtn and I need to give them 2 active reference sites - big ones - our project evevntually will have 180,000 users. At the moment the reference sites that we have to give as exmaples must have cost over 3 years ( implementation, support, h/w, salaries and other etc ) OVER 1.7 million euros. Does your installation qualify? If so could I email you a standard letter with the following details:
Name of Academic Institution, Short desciprion of project - 2 paragraphs, Duration of project, Budget, Current phase of project, name of company that performed the implementation if different, Contact details
so that you can fax back to me??
Is there any other installation that qualifies?? HELP!!! We have to sumit project in 4 days.
Thanks- Daphne Demetriades
I think you call a wrong number !!!
We have a project for about 200.000 users but it's only a project for next year.
I think it will be difficult for you to find such an existant system.
In fact, i know that one of the most important configuration is Moodle.org with more than 120.000 users (but i don't remenber exactly the number)
I know that a project like our's is building in UK, but it's a project.
4 days seems to be very short to find examples, but Moodle is a very attractive Learning Content Management System, and i'm sure will be a good choice for your government.
If you want to compare, you can use an old document we created before choosing Moodle in december 2004 ... http://wwweat.univ-tlse1.fr/Fichiers/EquipeTechnique/DocFOAD/Actualites/comparaison-plateformes-041223.xls
manay thanks for you inout and your comparison chart. I can just about udnerstand the french in the tables so it is very helpful. I was udner the impresison that you have already installed Moodle??
Sorry for that.
FYI Open University of UK is the biggest.
Don't worry about your impression. In fact, we use Moodle for both French Numeric University of Law, and University of Law in Toulouse (south of France).
We have 500 students in the first one's and 17.000 students in the second's, so i can say that we have already installed Moodle, and twice ...
But if you wanted to know configuration for high number of students from 3 years ago ... we don't have this experience !!!
I'll send you, in private message, the configuration we will install for 200.000 students at the beginning of 2007 ... if it can help you !!!
Happy that our comparison chart can help you for choice, even if it's an old work ...
