Loadbalancers facilitate scale-out and resiliency for the front-tier of an application and can enhance the performance of SSL-secured endpoints. An emerging trend is to use load balancers for all layers of the application. These load balancers bring valuable new capabilities in resilience (throttling, circuit breakers), enabling continuous deployments (routing or content switching), visibility (tracing, debug, anomaly detection), and compliance to a microservices based deployment. These are sometimes embedded in the microservice (e.g., Netflix Ribbon) and sometimes as a sidecar (AirBnB Synapse), or alternatively, deployed as Containers. Containerized Load Balancers are a perfect fit for some of these jobs, especially in the context of K8s, Swarm and ECS. The talk will discuss these container deployment architectures and point the way forward to new use cases (multi-Cloud, SDN, security)
