No, there is no UI component for ELB. Everything has to be done through configuring physical files.
Elastic LoadBalancer 2.1.0 is based on Hazlecast dependent clustering. This has two parts, one is load balancing and the other is elasticity. Load Balancing is simply distributing workload among a number of endpoints configured in a static or dynamic manner. Elasticity is simply scaling, ie monitoring load on worker nodes and starts or terminates nodes based on need on an IaaS environment.
Not only manages when a node goes down but also depending on load it can spawn new nodes to handle and if the load is low it can kill unwanted instances in an IaaS environment.
