NET303: A Day in the Life of a Cloud Network Engineer at Netflix

Netflix is big and dynamic. At Netflix, IP addresses mean nothing in the cloud. This is a big challenge with Amazon VPC Flow Logs. VPC Flow Log entries only present network-level information (L3 and L4), which is virtually meaningless. Our goal is to map each IP address back to an application, at scale, to derive true network-level insight within Amazon VPC. In this session, the Cloud Network Engineering team discusses the temporal nature of IP address utilization in AWS and the problem with looking at OSI Layer 3 and Layer 4 information in the cloud.
