But let's take a step back into thinking what are the common design patterns in building a microservices architectures. Varying from Request Response, Signal Slots, Service Discovery, Load Balancing, Error handling Monitoring. Then through code samples and demos we address these using Gilmour, a microservices Library over non-HTTP transports.
