Hardware and performance

Hi

> Please suggest if the above hardware config is fine or need to be changed.

Unfortunately there is no yes or no answer to this question. It all depends on too many things. Check the documentation: http://docs.moodle.org/en/Performance and http://docs.moodle.org/en/Performance_FAQ

> We planned to have one live Moodle server, one database server and one load balancing back up server. [...] Please note the courses will reside outside in local web servers and Moodle will launch the courses from these local servers.

Could you explain your architecture in bit more detail? See for example this forum discussion "Moodle clustering" http://moodle.org/mod/forum/discuss.php?d=57202 also http://docs.moodle.org/en/Performance#Scalability

>The proposed software setup options are:

> 1. Windows 2003/Apache/MySQL
> 2. Windows 2008/IIS7/MySQL
> 3. Windows 2003/IIS/MSSQL

May I know the reason why almost all Microsoft? A good example of the general openion of this forum could be seen in the discussion "Large scale Moodle Host Questions" http://moodle.org/mod/forum/discuss.php?d=132847 also check http://docs.moodle.org/en/Performance#Operating_System

> what would be the ideal internet bandwidth for Moodle if 500 concurrent users access the LMS from different locations in the country.

I thought that is pretty simple: If the server hat 1 GBit/s uplink, each of the 500 concurrent users has 2 MBit/s on the average.
