CloudWatch Retention Periods practice test
Retention periods in CloudWatch refer to the duration that CloudWatch will store historical data for a particular metric. By default, CloudWatch retains metric data for 15 months. However, the granularity of the data retention varies depending on the age of the data. CloudWatch retains data points with a one-minute granularity for 15 days, data points with a five-minute granularity for 63 days, and data points with a one-hour granularity for 455 days (around 15 months). CloudWatch Logs, on the other hand, have a default retention period of 'Never Expire', but you can set a custom retention period, ranging from 1 day to 10 years for log data, depending on the needs of your organization. It is essential to set appropriate retention periods to manage storage costs while ensuring data is available for analysis and historical trends.
