A JFrog service (or application) running in HA mode represents a cluster of two or more nodes that share the common resources.
You can run all JFrog services (Artifactory, Xray, and Distribution) in HA mode. The load balancer forwards the requests to the Artifactory router microservice, which in turn delivers the messages to the desired JFrog service.
Each cluster node runs all the microservices. For more information, see System Architecture.
