Episode notes

In this episode, Meg Ashby, a senior cloud security engineer shares how her team tackled AWS’s centralized VPC interface endpoints, a design often seen as an anti-pattern. She explains how they turned this unconventional approach into a cost-efficient and scalable solution, all while maintaining granular controls and network visibility. She shares why centralized VPC endpoints are considered an AWS anti-pattern, how to implement granular IAM controls in a centralized model and the challenges of monitoring and detecting VPC endpoint traffic.
