How can we use DOJO from CDN in OpenSocial App?

What are the pros and cons of hosting a PHP/MySQL website on a personal home laptop while offloading storage to S3 and distribution to CDN? ...

• I am concerned about the costs of running an EC2 instance and  not happy with i/o speeds . Instead I am thinking of using my laptop  for the web application . To give you an idea about the app (  It is a  user-generated site with video uploads and profiles . I`ll be using php  mysql with memcached ) My PC : Windows 8 (can be changed to Ubuntu or any linux distro) , 4GB RAM , AMD A8 , (512 MB + 2gb ) video memory . Workflow : User visits the website and uploads a video . Using a file processing  service , the file is uploaded to my S3 store . It is then transcoded  using AWS transcoder and the URLs for playing are stored back to my  database on the laptop . Amazon cloudfront is used as CDN . I can free up any amount of spcae required for mysql (in TB range) if  required , although seems unnecessary given how it will only be text . Should I be worried about my upload speeds ?They are pathetic at 512  kbps on a good day . But , if I have offloaded the heavy duty work of  video upload and transcoding , the only thing that remains to be served  is text and I can find ways to minimize their impact for every user .I  can sacrifice and not run any other major applications while the website  is up . I plan to use a lot of memcached queries . Ec2 for same amount of  storage and memory are very expensive to me (the main reason behind this  complicated decision ) . Is there any minor or important link I`m  missing ? Thank you for helping .

• Answer:

  Look at the http://aws.amazon.com/sdkforbrowser/.  You may be able to craft a static web page hosted in S3 that removes the need to upload video via a dedicated web server and: uses web identity federation for authentication uploads directly from browser to S3 (CORS) optionally appends info about uploads to an SQS queue (again CORS) You will need to trigger the transcoding, but could perhaps do that from a t1.micro EC2 instance that you launch from the spot market to keep costs down.
