These business needs are affecting how we build applications.įor more information about the Azure approach to microservices, see Microservices: An application revolution powered by the cloud. Improved resource utilization to reduce costs.Faster delivery of features and capabilities to respond to customer demands in an agile way.A service that's built and operated at scale to reach customers in new geographic regions.What has changed over the last few years is that developers are building distributed applications for the cloud. Typically, a tiered approach is used, with a back-end store, middle-tier business logic, and a front-end user interface (UI). Step 7: Open the Netfli圎urekaNamingServerApplication.For software developers, factoring an application into component parts is nothing new. Step 6: Extract the zip file and paste the folder in the Spring Tool Suite (STS) workspace and then import it.įile -> Import -> Existing Maven Projects -> Next -> Browse -> Select the netflix-eureka-naming-server project -> Finish Step 4: Add the following dependencies: Eureka Server, Config Client, Actuator, and DevTools. We have provided netflix-eureka-naming-server. Let’s follow the steps specified above:Ĭreate a component for the Eureka naming server Once the instances of currency-exchange-service are registered with the Eureka naming server, then we will use the Ribbon to find the detail from the naming server. Connect CurrencyExchangeService to the Eureka naming server.Update the Currenc圜alculationService to connect to the Eureka naming server.Create a component for the Eureka naming server.There are a lot of steps that are involved in setting up the Eureka naming server are as follows: In the next step, we will set up a Eureka naming server. Service registration and service discovery are the two important features of the naming server. ![]() The process of providing instances to other services is called Service Discovery. The naming server provides the instances of CurrencyExchangeService that are currently running. The Currenc圜alculationService first talk with the Eureka naming server. Whenever a service wants to talk with another service, suppose Currenc圜alculationService wants to talk to the CurrencyExchangeService. The registration of microservice with the naming server is called Service Registration. Whenever a new instance of a microservice comes up, it would register itself with the Eureka naming server. All the instances of all microservices will be register with the Eureka naming server. ![]() The Eureka naming server comes into existence when we want to make maintenance easier. If we keep on changing in the Currenc圜alulationService, based on how many CurrenyExchangeService are active right, then, it becomes very difficult to maintain. In this section, we will be able to increase or decrease the number of instances dynamically. Based on the load, we can increase or decrease the number of instances of the services. If the Ribbon wants to distribute the load to the new server, we need to add it to the configuration. Here a question arises, will ribbon be able to distribute the load to it? Suppose that we want to start another instance of currency-exchange-service that is CurrencyExchangeService3 and launch it on port 8002. Eureka naming server fills the gap between the client and the middle tier load balancer. Because of its inherent nature, server ups and down. We have another load balancer application, which is known as AWS Cloud. It also comes with a Java-based client component, the eureka client, which makes interactions with the service much easier. Eureka naming server comes with the bundle of Spring Cloud. The naming server registers the client services with their port numbers and IP addresses. Each microservice registers itself with the Eureka naming server. Eureka naming serverĮureka naming server is a REST-based server that is used in the AWS Cloud services for load balancing and failover of middle-tier services.Įureka naming server is an application that holds information about all client service applications. The naming server is a computer application that implements a network service for responding to queries against a directory service. In this section, we will set up the Eureka naming Server. In the previous section, we have configured the Ribbon and distributed the load between the two services. ![]()
