Spring Boot Admin Server

The Admin Server can represent the UI dashboard of the Spring Boot applications, and it can monitor an application and represent the dashboard metrics of the client server’s health.

Key Terminologies:

• Admin Server: The spring boot server is an application that can provide a web-based UI for managing and monitoring the spring boot applications.
• Instances: These can be defined as the individual spring boot applications that are registered with the spring boot admin server.
• Application Registry: It is a central registry maintained by the Springboot admin server that keeps track of registered client applications.
• Event Bus: It is a mechanism for broadcasting events from the spring boot and admin server to connect clients. It is used to provide real-time updates to the UI.

Spring Boot Admin Client

Spring Boot Admin Client is a simple spring boot application that includes the spring boot client library and allows the application to register with the spring boot admin server for monitoring and managing the service.

Key Terminologies:

• Admin Client: It is a Spring Boot Admin Client Library that allows the application to register with the Spring Boot admin server.
• Registration: It can be the process by which a client application registers with the admin application, and it’s responsible for providing monitoring information.
• Actuator Endpoints: Spring Boot Actuator exposes various information about the application, such as health, metrics, and environment details.
• Health Indicator: It is a component that provides information about the benefits of the spring boot application.

In Sprint Boot, Admin and Client can be implemented so that the client can be registered with the server, and then the server maintains the client’s service health and availability, scales up the service, and also measures the representation of the client.
