Clusters
A cluster is a set of LBAgent forwarding nodes.
Load Balancing Cluster
Contains the load balancing cluster and nodes.
The load balancing function of On-premise provided by OneCloud platform requires administrators to deploy load balancing clusters and LBAgent forwarding nodes first. The OneCloud supports load balancing multi-cluster function, users can configure load balancing cluster and forwarding node LBAgent under the cluster according to their requirements, and deploy the cluster and forwarding node before deploying load balancing instances, etc. The cluster is a collection of LBAgent forwarding nodes, and only one forwarding node in the cluster is in MASTER at the same time, which is used to monitor the IP address and port configured by the load monitoring instance and forward user requests to the back-end server for processing, etc. When the MASTER forwarding node fails, the other forwarding nodes in the cluster will automatically switch to MASTER to ensure high availability of business.
Nodes
The nodes in the load balancing cluster are used to listen for load balancing instances and forward client requests to the backend servers according to the listening and forwarding rules.
