SysAdmin Amazon EC2/S3 & Drupal setup | SM

Hello,

Require a EC2/S3 expert to tweak and configure a drupal site running on AWS that we notice not performing as it should.
We are preparing for launching a project in the next week and we need to make sure all is configured correctly.
We have provisioned the Centos+Virtualmim AMI and installed drupal afterwards.

Appreciate your assistance.

Regards
George
