Conclusion & Critical Evaluation

AWS suffers from many outages:On April 20, 2011, EBS service became "stuck"

and were unable to read/write requests.On June 29, 2012, several websites were taken

offline, storm in in Northern Virginia.On October 22, 2012, a major outage occurred.1)AWS should ensure resolving these problems

without outage happens.2)AWS should focus on building tools that will

make application plugging to the cloud easily.
