Application Live View APIServer	This Tanzu Application Platform component is the part of Application Live View that generates a unique token when a user receives access validation to a pod. The Application Live View connector component verifies the token against the Application Live View APIServer before proxying the actuator data from the application. This ensures that the actuator data is secured and only the user who has valid access to view the live information for the pod can retrieve the data.
Application Live View back end	This Tanzu Application Platform component is the central server for Application Live View that contains a list of registered apps. It is responsible for proxying the request to fetch the actuator information related to the app.
Application Live View connector	This Tanzu Application Platform component is the part of Application Live View that is responsible for discovering the app pods running on the Kubernetes cluster and registering the instances to the Application Live View back end for it to be observed. The Application Live View connector is also responsible for proxying the actuator queries to the app pods running in the Kubernetes cluster.
Application Live View convention server	This Tanzu Application Platform component is the part of Application Live View that provides a webhook handler for the Tanzu convention controller. The webhook handler is registered with Tanzu convention controller. The webhook handler detects supply-chain workloads running a Spring Boot. Such workloads are annotated automatically to enable Application Live View to monitor them.

Service instance	A service instance is an abstraction over one, or a group, of interrelated service resources that together provide the functions for a particular service. One of the service resources that make up an instance must either adhere to the definition of provisioned service, or be a secret conforming to the service binding specification for Kubernetes. This guarantees that you can claim a service and subsequently bind service instances to application workloads. You make service instances discoverable through service instance classes.

Services Toolkit	This Tanzu Application Platform component provides backing for service capabilities. This includes the integration of an extensive list of cloud-based and on-prem services, through to the offering and discovery of those services, and finally to the claiming and binding of service instances to application workloads.
