Healthcare demands resilient software. Healthcare systems are resistant to change, as change can be viewed as a threat to system availability. To scale and modernize these systems, software engineers have to build confidence in how they can continually introduce change.    

This talk will cover how Cerner evolved their service workloads and applied gameday exercises to improve their resiliency. It will focus on how they transitioned their Java services from traditional enterprise application servers to a container deployment on Kubernetes using Spinnaker. It will share how they standardized their service deployment to have consistent instrumentation to get deep insight into the overall behavior of their system. It will explain strategies for how they applied traffic management approaches to safely introduce chaos engineering experiments, improving their overall understanding of the system.
