condition data from bike sensors. The application also receives rental transaction data from the
associated mobile app.
The application uses Amazon DynamoDB as its database layer. The company has configured DynamoDB
with provisioned capacity set to 20% above the expected peak load of the application. On an average
day, DynamoDB used 22 billion read capacity units (RCUs) and 60 billion write capacity units (WCUs). The
application is running well. Usage changes smoothly over the course of the day and is generally shaped
like a bell curve. The timing and magnitude of peaks vary based on the weather and season, but the
general shape is consistent.
