The following objects are configured automatically by using the LBaaS workflow in the F5 LTM:

• Node: It represents the IP address of a physical or virtual instance in a network, such as a web server or an application server. A single node can have many application services running different or same kind of services associated with a pool member.
• Pool Member: It is union of an IP address and a port number that defines an application service that resides on a node. A pool member is obtained by a BIG-IP system.
• Pool: Load balancing can be accomplished by grouping one or more pool members and choosing suitable pool members. Load balancing policy should be configured on a pool with the specific pool members.
• Virtual server: It is a kind of listener which permits matching traffic types consisting of virtual server IP and port and forward them to pool members as per load balancing policy. All traffic gets blocked as the F5 LTM is a default-deny system. Virtual servers are ideal units that connect the clients.
