Amazon Virtual Private Cloud (Amazon VPC) Flow Logs helps you understand network traffic patterns on AWS by providing network telemetry data about the IP traffic flowing to and from ENIs in your VPC. It lets you perform numerous analytics tasks, such as diagnosing overly restrictive security group rules, monitoring traffic that is reaching an instance, […]

Traditionally, communication service providers (CSPs) in the telecom industry have used a Virtual Routing and Forwarding (VRF) technique to segregate their data center (DC) networks per each network domains; for examples of domain such as Operation, Administration & Management (OAM), signaling, roaming, and user traffic networks. Each VRF domain in the data center must also […]
