Contact me (https://chrisrichardson.wufoo.com/forms/zgp4xr60erb04x/) Pattern: 3rd Party Registration Context You have applied either the Clientside Service Discovery pattern (clientsidediscovery.html) or the Serverside Service Discovery pattern (serverside discovery.html). Service instances must be registered with the service registry (serviceregistry.html) on startup so that they can be discovered and unregistered on shutdown. Problem How are service instances registered with and unregistered from the service registry? Forces Service instances must be registered with the service registry on startup and unregistered on shutdown Service instances that crash must be unregistered from the service registry Service instances that are running but incapable of handling requests must be unregistered from the service registry Solution A 3rd party registrar is responsible for registering and unregistering a service instance with the service registry. When the service instance starts up, the registrar registers the service instance with the service registry. When the service instance shuts downs, the registrar unregisters the service instance from the service registry. Examples Examples of the 3rd Party Registration pattern include: Netflix Prana (https://github.com/Netflix/Prana) a "side car" application that runs along side a nonJVM application and registers the application with Eureka. AWS Autoscaling Groups (http://aws.amazon.com/autoscaling/) automatically (un)registers EC2 instances with Elastic Load Balancer Registrator (https://github.com/gliderlabs/registrator) registers and unregisters Docker containers with various service registries Clustering frameworks such as Kubernetes (https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/services.md) and Marathon (https://mesosphere.github.io/marathon/docs/servicediscoveryloadbalancing.html) (un)register service instances with the builtin/implicit registry Resulting context The benefits of the 3rd Party Registration pattern include: The service code is less complex than when using the Self Registration pattern (selfregistration.html) since its not responsible for registering itself The registrar can perform health checks on a service instance and register/unregister the instance based the health check There are also some drawbacks: The 3rd party registrar might only have superficial knowledge of the state of the service instance, e.g. RUNNING or NOT RUNNING and so might not know whether it can handle requests. However, as mentioned above some registrars such as Netflix Prana perform a health check in order to determine the availability of the service instance.
