Clustering stateful services for high availability with Consul
Ultimately scaling wasn't as big of a concern as availability. I've included a link below to the documentation for using Consul to facilitate leader election. Every component of the service is being watched by Riemann, if the component fails or if the Consul agent dies, the lock on the session...

Scaling stateless and stateful services
The stateless services in Cloud App Management are automatically scaled using Horizontal Pod Autoscaler (HPA). HPA scales up and down the number of replicas based on the CPU usage of the service. By default, the HPA upscale-delay is 3 minutes, and HPA downscale delay is five minutes.
