An API Gateway is a critical component in modern software architecture that acts as a central entry point for a collection of microservices or a set of APIs. It provides a unified interface to clients, simplifying and securing the client’s interaction with a set of services. Here’s an introduction to API Gateways and their key … Read more
Distributing calls using Eureka and Ribbon in a microservices architecture is a powerful way to achieve dynamic load balancing and service discovery. Eureka serves as the service registry, allowing microservices to register and discover each other, while Ribbon is used for client-side load balancing. Here’s how to distribute calls using Eureka and Ribbon in a … Read more
To connect microservices to an Eureka Naming Server, you need to configure your microservices as Eureka clients. This involves adding the necessary dependencies and configuration to enable the microservices to register themselves with the Eureka server and discover other services. Below are the steps to connect microservices to an Eureka Naming Server using Spring Cloud, … Read more
Eureka is a REST-based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers. Eureka Naming Server, often simply referred to as Eureka, is a core component of Netflix’s open-source Eureka service registry system. It provides service registration and discovery, allowing microservices … Read more
Ribbon is a client-side load balancing library developed by Netflix. It is often used in microservices architectures to distribute incoming requests across multiple instances of a service for improved scalability, availability, and fault tolerance. Ribbon works in conjunction with other components, such as Eureka for service discovery and Feign for making HTTP requests, in the … Read more
Feign is a Java-based declarative web service client developed by Netflix. It simplifies the process of making HTTP requests to RESTful web services by allowing you to define API requests as Java interfaces, and it handles the rest of the HTTP communication for you. Feign is often used in microservices architectures to communicate between services. … Read more
Invoking the currency-exchange-service from the currency-conversion-service in a microservices architecture typically involves making an HTTP request to the currency-exchange-service API. Here’s how you can achieve this: Step 1: Create or Use the currency-exchange-service Ensure that you have a working currency-exchange-service that provides exchange rate information for different currency pairs. This service should have API endpoints … Read more
Setting up a Currency Conversion Microservice involves creating a service that can convert between different currencies based on exchange rates. This microservice typically communicates with other services to fetch exchange rates and perform the conversion. Here’s a step-by-step guide to setting up a Currency Conversion Microservice: Step 1: Create a Spring Boot Project Use Spring … Read more
