Codeigniter on aws e2

Hi, i had created a dynamic web application using codeigniter at local end using xampp, Now i wish to put this application on cloud using aws e2, can anyone please tell me how to do so

Do you mean EC2?

If so, you'll have to load your application onto EC2. A base Ubuntu instance on EC2 also doesn't have much installed so you'll have to make sure you have PHP, MySQL... installed. Then you'll pull your code onto it.

This is a decent guide on how to get a LAMP stack going

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
