Our Journey of Implementing TLS at Scale for Services on Kubernetes

Abstract: 

TLS is the industry standard for encrypting communication between endpoints, however there are unique challenges to implementing TLS in a microservice environment. For example, you may have hundreds of microservices running on multiple environments, how do you provision and disburse TLS certificates in a scalable way, while causing least disruption to uptime? How do you easily manage day 2 operations of those TLS certificates such as certificate renewal or revocation? In this talk, we present Diploma, our Vault based Certificate generation system and Chancellor, a Kubernetes controller that disburses certificates to workloads using Kubernetes API, providing certificates for 40+ microservices in production and serves 2000+ certificates a day in development and test environments.
