This question already has an answer here:

How do you do load testing and capacity planning for web sites? 3 answers

There are few things that I would like to know here.

What server configuration do I need. And if I am deploying it on EC2 how many VMs do I need and what should be their configuration.

What options do I have to do a load testing for 1 million concurrent users.

Any pointer to (for php) how to code or what to keep in mind for such application.

This is for sure that I don't exactly know what to ask because this is my first application on this scale. But one thing is clear that this application should pass a load test of 1 million concurrent request.
