Amazon CloudWatch Network Monitoring adds flow visibility between Regions

With flow monitors in Amazon CloudWatch Network Monitoring, you can now monitor network performance of traffic flowing between AWS Regions across the AWS global network. Flow monitors provide near real-time visibility of network performance for workloads between compute instances such as Amazon EC2 and Amazon EKS, and AWS services such as Amazon S3 and Amazon DynamoDB. Flow monitors provide metrics to help you rapidly detect and attribute network-driven impairments for your workloads.

With this release, flow monitors now help you to assess whether network performance issues on the AWS global network between a local and a remote Region are impacting your workloads. Because the flow monitor's network health indicator (NHI) now also captures the health of the AWS global network on your workload’s network paths between Regions, you can quickly identify whether impairments in a local Region, in the AWS global network, or in the remote Region are affecting your workloads. This feature extends network visibility for flows to a remote Region’s public IP address, and for private traffic flowing to a remote Region over Amazon VPC peering or AWS Transit Gateway peering.
