I am planning to install Moodle (php application) with MySql database. At present i have it on a VPS with 8GB Ram 6 CPU centos but it is not efficiently catering the need of even 100 concurrent users.
What way I can use DigitalOcean to cater the need for 1000 concurrent users who may take quiz at same time for online examination. There may not be any memory intensive multimedia but simple online quiz with multiple choice text/image questions.
Please provide me a hardward architecture approach I can use to cater my needs.

1000 users to do a quiz on Moodle is a huge amount. I have worked on Moodle platforms with 1,000,000 users in Spain and never did 1000 users ever simultaneously do a quiz. That said, Moodle quizzes are very server intensive and do require a lot of server resources.

Recently we were having issues with Moodle quizzes with around 800 concurrent users and we had 8 webserver with x 4CPU Xenon’s, each with 32GB of Ram and 4 X Mysql, clustered with the same processors and RAM

As you can see, Moodle isn’t great with the Quiz Module
