 Using Amazon CloudWatch Metric Streams and Amazon Data Firehose, you can get CloudWatch metrics into Datadog with only a two to three minute latency. This is significantly faster than Datadog's default API polling approach, which provides updated metrics every 10 minutes.

This level of service for detailed metrics also applies to granularity, with some metrics being available per minute and others per five minutes.
