Spring-cloud-config (configuration Center ), Preface In a distributed system, due to the large number of services, in order to facilitate unified management of service configuration files and real-time updates, the distributed configuration center component: spring-cloud-config, it supports configuring services in the memory (local) of the configuration service and remote Git repository. This section describes how to use the Git repository as the configuration source. Open Source Address: https:

If you have a friend who has dubbo/dubbox experience, see this diagram below, it must be familiar, is the most basic way of SOA architecture.In contrast to Dubbo, the 3 major elements of spring cloud are implemented with the following components:1. Registration Center:Spring Cloud uses Eureka server by default for the registry, and Dubbo uses zookeeper by default. Eureka's registration information is stored in a double-decker map object, in other word

Summary: Spring cloud is built on spring boot to simplify the toolset for distributed system building, providing developers with some common patterns for rapidly building distributed systems.For example: Configuration Management (config management), Service Discovery (services discovery), circuit breakers (circuit breakers), intelligent routing (intelligent routing),Micro-agent (micro-proxy), control bus, one-time token (one-time tokens), Global lock (Globals locks), leading the election (leader

request is handled by. Load balancing is also used when the request is forwarded to the service. Services sometimes also require mutual access. For example, there is a user module, the other services in the processing of some business, to obtain user data of customer service. A circuit breaker is required to handle time-outs and errors in the service invocation in a timely manner, preventing the overall system from being paralysed by one of the service's problems.

With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:AltWe implemented service registries and service registration and discovery using the Eureka in spring cloud netflix, while service consumption and balanced workloads across the ribbon or feign through the spring cloud Config enables the application of multi-enviro

1. Introduction　　The highly available distributed configuration Center, which is a microservices-ready configuration Center, is clustered to achieve high availability. Config-server and Config-client register with Eureka-server and Config-server multi-instance clustering deployment2. Retrofit Config-server1, we use the previously created Eureka-server project as a registry, port 87612, we will Config-server

The previous article described how a service reads a file from the configuration center, how the configuration center reads the configuration file from a remote git, and when the service instance is many, reads the file from the configuration center, you can consider the configuration center as a micro-service, clustering it to achieve high availability, the frame composition is as follows:First, the preparatory workContinue with the project of the previous article, create a

Original source: http://blog.didispace.com/springcloud2/In the previous article, "Spring Cloud Building MicroServices Architecture (a) service registration and discovery", we have successfully created a "service registry", Implementing and registering a "service provider: Compute-service". So how do we go about consuming the interface content of a service provider?RibbonThe Ribbon is a load balancer based on HTTP and TCP clients.

RABBITMQ Implementation Here's what we're going to do. The entire configuration process: preparation: Here we do not do new applications, but we need to use the previous chapter, we have implemented a few projects on Spring Cloud Config, if the reader does not understand it, it is recommended to read the 4th chapter.

In a few simple steps, build a micro service registry based on spring cloud, including several features: -Provide registration center to be registered by service provider -Service consumer finds the service location in the registry -High Availability (cluster) configuration 1, the introduction of dependence: Two dependencies need to be introduced: 2. Configuration: In order to configure a highly available registry cluster, 3 registries are configured to spare each other. Assume that the h

In the first two introductions, the client directly invokes the server side of the configuration Center to get profile information. So there is a problem, the client and server coupling is too high, if the servers to do the cluster, the client can only be routed in the original way, the server side changes the IP address, the client also needs to modify the configuration, not in line with the Springcloud service governance concept. Springcloud provides such a solution, we only need to register t

Have to say, Springcloud is indeed very strong, there are pivotal and Netfix is its strong backing and technical output. Finally, we chose t
