This talk will look at the technologies required to build a system of intercommunicating microservices. We’ll use Node.js for building two separate application tiers. Consul will maintain a registry of service instances, providing their hostnames and ports. Finally, we’ll use HAProxy to route client traffic to web services, dynamically reconfiguring it as instances come and go.

Attendees of this talk will understand how Service Discovery works and why it is needed in a dynamic microservice environment. This presentation includes working code samples and architectural diagrams.
