Amazon VPC Flow Logs now reflects AWS Service name, Traffic Path and Flow Direction

You can now add four additional metadata fields in your Amazon Virtual Private Cloud (Amazon VPC) flow logs, namely flow-direction, traffic-path, pkt-src-aws-service and pkt-dst-aws-service. With these enriched fields you can derive insights into the AWS services that your workloads are communicating with, differentiate between ingress and egress traffic flows and identify the next hop of your egress traffic, such as an internet gateway, a VPC peering connection or a virtual private gateway.
