QUESTION

Is there any way to reduce AWS CloudTrail latency?  Between the event time and alert time, there is a latency of about ~15 mins.  Can this be improved?

ANSWER

Currently, there are no implemented solutions to mitigate CloudTrail latency. The standard timeframe for CloudTrail to deliver an event after an API call is roughly 5 minutes. Similarly, if you have CloudTrail configured to send log files to your S3 bucket, this process occurs approximately every 5 minutes.

If you're observing a slight delay between parsing the event and creating an alert, rest assured that it falls within reasonable limits.
