In this video, Keith from Pinterest talks about their scalable access control solution for clusters of EC2 instances that need access to data in Amazon S3. You’ll learn how they built a token vending service using AWS Secure Token Service (STS) that allows them to bridge their internal concept of users and authentication to managed policies and AWS Identity and Access Management (IAM). This elegant solution provides layered, fine-grained access control and reduces the number of clusters that they need to spin-up.
