AWS Cloud WAN now supports Flow Logs

AWS Cloud WAN Flow Logs Support

AWS Cloud WAN now supports VPC Flow Logs, providing central visibility into IP traffic across your global network. Flow Logs capture detailed information for each flow, allowing you to understand how traffic moves across your core network without leaving your AWS Cloud WAN account.

Flow log records include IP addresses, ports, protocol, traffic volume, and packet-loss counters, along with Cloud WAN metadata such as segment, Region, service insertion hops, and attachment details. You can turn on Flow Logs for an entire core network, a single core network edge, or individual attachments. You can publish them to Amazon CloudWatch Logs, Amazon S3, or Amazon Data Firehose. Cloud WAN adds no charge for Flow Logs; standard charges apply for each destination.

What to do

• Enable Flow Logs for your core network, core network edge, or individual attachments.
• Choose your preferred destination for Flow Logs: Amazon CloudWatch Logs, Amazon S3, or Amazon Data Firehose.
• Monitor and analyze traffic patterns to troubleshoot connectivity and performance issues.
• Plan capacity from historical bandwidth trends and identify unusual traffic patterns.
• Keep records for security and compliance.
