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