Jesandco is a non-profit education organization that serves an international community. They have multiple Drupal sites in the Amazon cloud that we worked on: Standards for the 21st-Century Learner Lesson Plan Database, Achievement Standards Networkand our Mapping Service. Two of the three sites are Drupal 6, the latter in Drupal 7.
We were responsible to migrate the old systems into new Amazon cloud hosted systems Bitnami Ubuntu lamp stack also running on Amazon. Our expertise with Amazon EC2, RDF + Drupal projects for extracting data using SPARQL, Ubuntu and Bitnami helped in a quick, efficicient and successful migration.
