Netflix open sources Eureka mid-tier load balancer

With Netflix running so many services on Amazon’s Web Services (AWS) cloud, it needs to be able to find those services easily so that it can balance loads and manage failover. The video-streaming specialists have now open sourced Eureka, the software they use to meet that challenge. Eureka includes a REST-based server that allows servers to register with it when they come up and detects when they are down, and a client which talks to that service and does basic round-robin load balancing. Netflix has more sophisticated balancers in-house designed for their own needs.
