Spring Cloud

Spring Cloud’s main purpose is to give tools and services for managing and making distributed systems, especially in a microservices architecture. The developer wants to speed up the process of building patterns in distributed systems, these tools can fulfill their requirement. They include almost all from the management of configuration and service discovery to circuit breakers, intelligent routing, micro-proxy, short-lived microservices, and control bus, etc. In short, this Spring Cloud collective group of libraries and frameworks can be used for making and managing of cloud-based, distributed system.

Spring Cloud has a vast range of features that make a developer’s life very easy and smooth. e.g. services can seamlessly discover and share among each other, all credit goes to the convenience provided by the Netflix Eureka (Java-based open-source project that provides a RESTful interface for service) and similar implementations, and this is what we call Service Discovery, one of the key features of Spring cloud. Similarly, Configuration Management where Centralized and dynamic configurations are managed with the help of spring cloud configuration. Circuit Breaker delivers ways to control the failure cascades that is the circuit Breaker pattern.

Features like Distributed/versioned configuration, Service registration and discovery, Routing, and Service-to-service calls, etc. are some most important key features of Spring Cloud.

In Dependency configuration in order to use Spring Cloud BOM to Your Application Inside our application.

Spring Boot Actuator

Spring Boot Actuator’s main aim is to adding production-ready elements to the Spring Boot applications. It mainly helps in monitoring and managing the app once it is made to production.

Making the app and managing the app are the two most important parts of the application life cycle. That is why it is always recommended to monitor the app in both cases. So, Spring boot provides actuator dependency that helps in monitoring and making processes.

Spring boot actuator works in two phases first one is monitoring, and the second one is configuring, inside the monitoring spring-boot application comes and inside the configuration application.properties or application.yaml.

Because of the actuators in Applications reduce downtime, boost productivity, improve the security and increase the customer satisfaction.

This Spring boot actuator gives us detailed health info about the app status and it’s all connected services i.e. the Application health checks, it provides us with many different metrics to observe the implementation of the app i.e. the Environment information and Matrics collection. The main aim is not on the exchange between services, but rather on their respective performance and manageability.

In Dependency configuration in order to use Actuator Inside our application in pom.xml.

<dependencies>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-actuator</artifactId>
   </dependency>
