You are the new IT architect in a company that operates a mobile sleep tracking application. When activated at night, the mobile app is sending collected data points of 1 KB every 5 minutes to your middleware. The middleware layer takes care of authenticating the user and writing the data points into an Amazon DynamoDB table. Every morning, you scan the table to extract and aggregate last night’s data on a per-user basis, and store the results in Amazon S3. Users are notified via Amazon SMS mobile push notifications that new data is available, which is parsed and visualized by the mobile app. Currently, you have around 100k users. You have been tasked to optimize the architecture of the middleware system to lower the cost.

What would you recommend?

Αν αυτό γινόταν store επί τόπου και όχι ολόκληρο μαζεμένο κάθε πρωί;

Δεν κάνεις store κανένα δεδομένο, απλά κάθε πρωί στέλνεις σε κάθε χρήστη masked links για goatse, halflife2-joy κλπ.
problem solved.
