Ideally, you could use AWS/EC2 platform to host such infrastructure which could scale up/down as required , throw it away when done and just pay for what you use. Few inputs: - AWS offers Elastic Load Balancer which is massively scalable. - You could split your application into Apache | NFS \ Backend DB and scale each part individually. - Use In memory cache such as memcache for db, varnish for http cache. This will reduce the load on the backend servers a lot. - Use Autoscaling to scale up and down as your traffic changes - Use spot instances for web servers with autoscaling. You will end up doing considerable cost savings. I have not setup scalable infrastructure for moodle in specific, but have done it for multitude of other LAMP stacks such as magento, drupal, custom php apps and so on. Each has its own specific challenges, but underlyting architecture remain same.
