At Improbable we’re building a platform for the next generation of Simulation, called SpatialOS. We’re hosting large scale Deployments of user Simulations inside our Clusters. Due to the real-time nature of Simulations, we needed a mechanism that would allow dynamic reconfiguration of parameters across multiple nodes of a Deployment. We leveraged etcd consistency and watch API to build a mechanism that allows developers to easily define code variables (Java annotated fields or Go flags) that change in almost real-time across hundreds of machines. While the main driver behind this highly flexible approach was our unique Simulation Runtime, the same mechanism is now powering our Platform’s operational configuration: request routing, rate limiting and experimental A-B testing.
