Want to deploy an Opencart setup on Amazon AWS with following architecture : - Amazon EC2 with Linux for application server - application server to be stateless having no session information or user files. - Database on Amazon RDS - Assets & Storage on Amazon S3 (Images, etc) - CDN with Amazon S3 - A load balancer from the Elastic Load Balancing service, to distribute traffic to application servers The site will be hosting thousands of photographs, so need the ability to upload files directly via FTP or any earlier method. MyPhpAdmin access required for database ---- Need help with setting up Assets & Storage on Amazon S3 along with CDN. I currently use Excel upload for bulk upload of my product data & FTP to upload downloadable files and images. And directly use phpmyadmin to link downloadable files with products.
