Amazon CloudWatch Now Supports Composite Alarms in AWS GovCloud (US) Regions

Amazon CloudWatch now supports composite alarms in AWS GovCloud (US) Regions. With Amazon CloudWatch composite alarms, you can combine multiple alarms to reduce alarm noise and focus on critical operational issues. You can easily combine multiple alarms together into alarm hierarchies that only trigger once when multiple alarms fire at the same time. This helps you stay focused on finding the root cause of operational issues to reduce system and application downtime.
