Question

A gaming company runs a leaderboard service on Amazon DynamoDB. Traffic follows a very predictable daily pattern: read and write volume ramps up gradually every morning, peaks in the evening, and drops overnight. The workload is steady and forecastable with no sudden unexpected spikes. The team wants the lowest possible cost while ensuring the table always has enough throughput to avoid request throttling during the daily peaks. Which approach best meets these requirements?

Accepted Answer

Use provisioned capacity mode with DynamoDB auto scaling configured with a target utilization to adjust read and write capacity as demand changes.

Answer

Use on-demand capacity mode so DynamoDB automatically accommodates the daily traffic pattern without capacity planning.

Answer

Use provisioned capacity mode with fixed read and write capacity units set to the highest observed peak value.

Answer

Add a DynamoDB Accelerator (DAX) cluster in front of the table to eliminate the need to scale table capacity.
