1. Comparison of spring cloud and dubbo, what are their advantages and disadvantages
dubbo because it is binary transmission, bandwidth will be less
springCloud is http transmission protocol, the bandwidth will be more while using the http protocol typically use JSON messages, consumption will be greater
dubbo of development more difficult, because the jar package dependencies dubbo many large projects can not be solved
springcloud interface agreement relatively free and loose, it requires strong administrative measures to restrict the interface disorderly upgrade
dubbo registries can choose a variety zk, redis, etc., registry springcloud can only be used eureka or self-study
differences 2.spring cloud and spring boot of
SpringBoot focus on quick and easy development of a single individual micro-services.
SpringCloud micro coordination of services finishing governance framework of global concern, it SpringBoot development of a monomer integrate and manage micro services,
Between the various service providers, configuration management, service discovery, circuit breakers, routing, micro broker, event bus, global lock, selection decisions, such as distributed session integration services.
SpringBoot can leave SpringCloud independent development projects, but can not do without SpringBoot SpringCloud, belongs to the dependencies.
SpringBoot focus on quick and easy development of a single micro-serving individuals, SpringCloud attention to service global governance framework.
3. How springboot services into spring cloud
