AWS configuration, setup, php, joomla

Joomla! Knowledge preferably. But is NOT a must !! =) I am looking forwad to start my own web application. Help from smart people is welcome. If you don´t have experience with AWS, please, stay away!!! Don´t ask what AWS means. =) 1st Phase*********************** (This is what I´m interested in getting done, the 1st phase) AWS Knowledge is a must. Build AWS Website Infrastructure. -I choose AWS because of the freetier and because it´s the standard for other CloudServices, like Bitnami. -AWS Services: -How should I start the web application so it can be scalable? -Refer to image [login to view URL] -The application overall consists of: -Joomla -MySQL -External application -Videos from YouTube (possibly from our AWS server in the future) -Should Joomla! Database work on EBS or S3? Should it have a separate instance(separate virtual machine)? if you are new to AWS please don´t Bid. Can this be modified as system grows? -Should Joomla!(2.5.2) website be on its own instance? Can it share the same AMI Instance with DB? -Should videos be on youTube or within our servers? -The thing here its not only scalable server performance and architecture, but I have a low budget, so I want to start with AWS freetier if possible. 2nd Phase*********************** (this is Not part of this project, is only the 2nd phase) -Website Construction -Minimalist Design is required [login to view URL] -put more examples -Website will hold: -Joomla -News, Articles, Videos, Content -Link to external application ex. link to [login to view URL] 3rd Phase*********************** (this is Not part of this project, is only the 3rd phase) -Content Creation -Writing articles -quotes -look for articles in bookmarks -Creating Videos -editing videos
