An application running on Amazon EC2 allows users to launch batch jobs for data analysis. The jobs are run asynchronously, and the user is notified when they are complete. While multiple jobs can run concurrently, a user’s request need not be fulfilled for up to 24 hours. To run a job, the application launches an additional EC2 instance that performs all the analytics calculations. A job takes between 75 and 110 minutes to complete and cannot be interrupted.
