Starting today, Amazon Virtual Private Cloud (VPC) customers can use AWS Transit Gateway Flow Logs in Israel (Tel Aviv), and Canada West (Calgary) regions. The expansion into these regions enables customers to export detailed telemetry information such as source/destination IP addresses, ports, and various metadata for all of their network flows. This feature provides customers with an AWS native tool to centrally export and inspect flow-level telemetry for all network traffic that is traversing between Amazon VPCs and on-premises networks via AWS Transit Gateway.
