Eureka

Eureka is a REST (Representational State Transfer) based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers.

At Netflix, Eureka is used for the following purposes apart from playing a critical part in mid-tier load balancing.

  • For aiding Netflix Asgard - an open source service which makes cloud deployments easier, in

    • Fast rollback of versions in case of problems avoiding the re-launch of 100's of instances which could take a long time.
    • In rolling pushes, for avoiding propagation of a new version to all instances in case of problems.
  • For our cassandra deployments to take instances out of traffic for maintenance.

  • For our memcached caching services to identify the list of nodes in the ring.

  • For carrying other additional application specific metadata about services for various other reasons.
