Role of Service Discovery in Microservices and How to Implement It with Eureka & Consul

Role of Service Discovery in Microservices and How to Implement It with Eureka & Consul

Introduction In modern cloud-native architectures, microservices have become the preferred style for building scalable, resilient, and independently deployable applications. However, this architectural model introduces dynamism and distribution: services may scale up or down, move between hosts or containers, and network addresses may change. In this context, service discovery emerges as Read more

How to Handle Schema Evolution in Microservices Communication

How to Handle Schema Evolution in Microservices Communication

In microservices architecture, services often evolve independently. Over time, this leads to changes in data contracts—commonly referred to as schema evolution. If not handled carefully, even minor schema changes can break inter-service communication, leading to data loss, runtime errors, or system outages. This article explores how to safely manage schema Read more
