However, requests may still arrive at the old Pod during the termination process. If the Pod is killed while handling ac...
Understanding Ribbon Load balancing can be implemented in two primary ways: Server-side load balancing (e.g., using Nginx) Client-side load balancing What is Ribbon? Ribbon is a Netflix open-source project that provides client-side load balancing capabilities. It offers various configuration options...
Microservices Architecture Overview Microservices architecture structures an application as a collection of loosely coupled services, where each service implements a specific business capability and can be developed, deployed, and scaled independently. Spring Boot provides comprehensive support for...
In distributed microservice architectures, handling inter‑service communication reliably and efficiently is critical. A service mesh provides a dedicated infrastructure layer that offloads traffic management, security, and observability from individual services. At its core, service discovery is a f...
The client module serves as the actual provider of services within a Spring Cloud environment. It registers itself with the service registry (Eureka server) to make its capabilities available to other components. Creating the client module follows a similar process to setting up the registry: Create...
Distributed architectures necessitate mechanisms to manage concurrent access to shared resources across multiple service instances. A coordination primitive is essential to enforce mutual exclusion and maintain state consistency. The Eureka service registry, while designed for service discovery, can...
Overview Eureka, created by Netflix, is a registry for service discovery in microservice architectures. Each provider registers itself with Eureka, while consumers query Eureka to locate instances. Although Netflix has ended active maintenance of Eureka 2.x, the Eureka 1.x implementation in Spring C...
