A company wants to release a new device that will collect data to track overnight sleep on an intelligent mattress. Sensors will send data that will be uploaded to an Amazon S3 bucket. Each mattress generates about 2 MB of data each night. An application must process the data and summarize the data for each user. The application must make the results available as soon as possible. Every invocation of the application will require about 1 GB of memory and will finish running within 30 seconds. Which solution will run the application MOST cost-effectively?
