Spring Cloud builds an enterprise-level bus-part one introduction and overview

introduction

Writing purpose

Background and meaning

There are many internal business systems in the enterprise, mutual calls are more complicated, interface maintenance costs are relatively large, and different systems use different development platforms, transmission protocols, data formats, etc., in this case, you need to consider using ESB .

Enterprise Service Bus (ESB) is a key part of the infrastructure used when building a service-oriented architecture (SOA) solution. It is a set of infrastructure functions that are implemented by middleware technology and support SOA. ESB supports services, messages, and event-based interactions in heterogeneous environments, and has appropriate service levels and manageability. In short, ESB provides functions to connect new and existing software applications within and across enterprises, and enables interaction between management and monitoring applications with a rich set of functions. In the SOA layered model, ESB is used between the component layer and the service layer. It can connect and integrate components on different platforms through a variety of communication protocols to map it into service layer services. The current mature and popular ESB frameworks are mainly: Spring Cloud, Dubbo, Enterprise Service Bus JBoss ESB.

At present, Spring Cloud is not well-known in China. When some Internet architects, technical VPs or CTOs are communicating, some do not even know the existence of the project. Perhaps this is also related to Dubbo, the domestic Alibaba open source service governance framework. In addition to the relatively complete Chinese documents of Dubbo itself, the architects of many technology companies are all from the Alibaba department. So based on the current situation, it is still Dubbo in China in the short term. The world.

Introduction to Spring Cloud

project	detailed
Spring Cloud Config	Unified configuration management, support local/Git/SVN.
Spring Cloud Netflix	The various components provided by Netflix include Eureka, Hystrix, Zuul, Archaius, etc.
Spring Cloud Bus	The event bus that uses a distributed message mechanism to connect services and service instances is very effective for cross-cluster status notifications, such as configuration change events.
Spring Cloud for Cloud Foundry	Integration with CloudFoundry
Spring Cloud Cloud Foundry Service Broker	Provide Service Broker to manage related services
Spring Cloud Cluster	Support for Leadership election and common stateful patterns provided by abstracting and implementing Zookeeper, Redis, Hazelcast, Consul, etc.
Spring Cloud Consul	Use Hashicorp Consul for service discovery and configuration management
Spring Cloud Security	Add OAuth2 security control to the application
Spring Cloud Sleuth	Provides a Tracing mechanism compatible with Zipkin/HTrace/ELK, etc.
Spring Cloud Data Flow	The easy-to-use DSL, extended GUI and REST-API together provide a simplified microservice data flow pipeline mechanism.
project	detailed
Spring Cloud Stream	Use Apache Kafka or RabbitMQ to send and receive messages, providing a lightweight event-driven microservice framework for connecting with external systems.
Spring Cloud Stream App Starters	Based on spring boot, integrate with external systems
Spring Cloud Zookeeper	Use Apache Zookeeper for service discovery and configuration management
Spring Cloud for Amazon Web Services	Used to simplify and better integrate with Amazon Web Service
Spring Cloud Connectors	Make it easier for Paas applications to interact with back-end services (such as databases)
Spring Cloud Starters	Simpler management (similar to other starters)
Spring Cloud CLI	Use CLI to create various components of Spring Cloud.

Spring Cloud is an ordered collection of a series of frameworks. It uses the development convenience of Spring Boot to cleverly simplify the development of distributed system infrastructure, such as service discovery registration, configuration center, message bus, load balancing, circuit breakers, data monitoring, etc., all can be done in Spring Boot development style To one-click launch and deployment. Spring does not re-manufacture wheels, it just combines the relatively mature and practical service frameworks developed by various companies, and repackages and shields them through Spring Boot style. The complex configuration and implementation principles ultimately leave developers with a set of distributed system development kits that are easy to understand, easy to deploy, and easy to maintain.

Spring Cloud contains multiple sub-projects (for multiple different open source products involved in distributed systems), such as: Spring Cloud Config, Spring Cloud Netflix, Spring Cloud CloudFoundry, Spring Cloud AWS, Spring Cloud Security, Spring Cloud Commons, Spring Cloud Zookeeper, Spring Cloud CLI and other projects.
