Overview A microservices gateway is a system that provides centralized authentication, security control, unified logging, monitoring, and rate limiting by exposing a single entry point. Spring Cloud Gateway Workflow A client sends a request to Spring Cloud Gateway. The request is first extracted and assembled into a gateway context by HttpWeb ...

Apache Dubbo RPC Framework Overview Apache Dubbo is a high-performance RPC (Remote Procedure Call) service development framework designed to address service governance and communication challenges in microservice architectures. The framework provides multi-language SDK implementations including Java and Golang. Microservices built with Dubbo in ...

Project Architecture Overview The system adopts a microservices architecture, decomposing business capabilities into independently deployable services communicating over lightweight HTTP APIs. Each service handles its own data storage and can be developed with dedicated technology stacks. The architecture diagram splits the monolith into servic ...

The Vert.x framework facilitates high-performance asynchronous programming. When a request arrives, it is delegated to the event loop rather than blocking threads. The server dispatches the task and continues processing immediately. Once the background operation completes, the result is returned via a callback mechanism, notifying the client. T ...

Previous implementations of Spring Cloud Config typically required clients to specify the server's URL directly using spring.cloud.config.uri. This approach becomes problematic when scaling the server into a cluster, as changes to the server's IP address or load-balancing setup necessitate manual updates to every client. To align with the servi ...

Spring Cloud Sleuth serves as a distributed tracing mechanism integrated within the Spring Cloud ecosystem. Its primary objective is to simplify the process of debugging and monitoring requests across microservices by injecting unique identifiers into service communications. In complex microservice architectures, an inbound request often traver ...

Currrent Project Architecture Issues Introducing Eureka In a typical project, the member center is often deployed as a cluster to handle high concurrency and large loads. For instance, if the member center runs on a single host that can only handle 10,000 requests, many concurrent requests would overwhelm it. By using a cluster (multiple serve ...

Local Transaction Fundamentals Database transactions guarantee ACID properties: Atomicity, Consistency, Isolation, and Durability. In monolithic applications, a single connection handles multiple table operations, enabling straightforward rollback mechanisms. Consider an e-commerce checkout flow: Inventory Service: Deducts stock quantities Ord ...

To facilitate communication between microservices, such as an Order Management system retrieving details from an Inventory system, client-side load balancing is essential. Spring Cloud Ribbon provides this capability seamlessly when integrated with Spring's RestTemplate. Project Configuration Begin by initializing the order management module. T ...

Integrating SkyWalking for Application Performence Monitoring in Spring Boot In a microservices environment, monitoring and tracing system performance is critical. Apache SkyWalking, an application performance management (APM) tool, enables real-time observation and analysis of microservice performance. This integration process involves configu ...
