In modern microservice architectures, Redis is widely used for caching, distributed locking, session storage, and rate limiting. However, the way you interact with Redis differs significantly between a traditional Servlet‑based service (blocking) and a WebFlux‑based gateway (non‑blocking). This guide explains both approaches and provides ready‑ ...

XML-based configuration remains a practical approach for managing Apache Dubbo RPC endpoints, particularly when decoupling infrastructure settings from application source code. This methodology facilitates environment-specific overrides, centralized version control, and clearer depandency mapping for complex deployments. Dependency Initializati ...

Installation and Startup Download the Nacos binary from the official GitHub releases page and extract it to a convenient location. Inside the extracted directory, conf/application.properties holds default settings, such as the web port (default 8848) wich typically does not need to be changed.

Docker and Distributed Systems Architecture Adopting a microservices architecture introduces scalabilitty benefits but also operational complexity. Unlike monolithic applications, distributed systems consist of numerous independent components that require individual management and deployment. As the number of services grows, deployment frequenc ...

Understanding Zuul Filter MechanismsThe core functionality of the Zuul API Gateway is driven by its filter system, which intercepts HTTP requests and responses to handle cross-cutting concerns. Filters are constructed to manipulate the RequestContext, which holds the state for the current request, including request and response objects, routing ...
