The book titled "Spring Cloud and Docker microservices architecture in action"-Li, which was completed in 2017-01-12, was written with the spring Cloud play Micro service architecture. Many friends want to first look at the source code, is now released.The code released this time: A total of 70 + Demo Covers Eureka, Ribbon, Feign, Hystrix, Zuul, Spring Cloud Config, Spring Cloud Bus, Spring Cloud Sleuth, Docker, Docker compose, and more.

This article is the sixth of a series of courses on "Internet high concurrency MicroServices architecture practice" The first five articles are: The cornerstone of micro-service-Continuous integration Access layer design of micro-service and isolation of static and dynamic resources Database design and read-write separation of microservices The non-state and containerized of micro-service Design of micro-se

Over the past two years, the authors have been involved in the MicroServices team in overseas deliveries to enhance the scalability of the Finance system for customers. The author's team, 3 pairs of development (pair programming, 2 dev for pair) Support 11 services for customers, and the continuous deployment pipeline (CD pipeline) is an essential technical practice. This sharing author will share the ongoing deployment (CD) under the

Load balancing is an essential name for any high-availability, high-load system. In a large-scale distributed computing system, a service in a single case, it is difficult to deal with a variety of unexpected situations. Therefore, load balancing is a solution that allows the system to distribute traffic in the event of a performance bottleneck or in some of these states. In the Springcloud system, many of Netflix's best products have been added, one of which is the Ribbon for server-side load b

decomposed, and the granularity is getting smaller. Until the micro-service architecture was born.Micro-service architecture is the inheritance of SOA architecture, but one of the most essential differences is that microservices are truly distributed and decentralized. Put all the "thinking" logic including routing, message parsing and so on inside the service, remove a unification ESB, light communication between services, is a more thorough split t

Quickly set up Feign in microservices and set up Feign in microservices Build a declarative REST client feign in the microservice architecture ].Feign is a declarative Web service client. This makes writing to the Web service client more convenient. Use Feign to create an interface and annotate it. It has support for pluggable comments, including Feign comments and JAX-RS comments. Spring Cloud supports Spr

gateway itself, or by external caches such as Redis or memcached. By returning cached data or default data, API gateway ensures that system errors do not affect the user experience.Netflix Hystrix is a very useful library for implementing remote service invocation code. Hystrix records those calls that exceed the pre-set limit values. It implements the circuit break mode, which allows the client to stop in an endless wait for unresponsive services. If the error rate of a service exceeds the pre

application development. Soon after 10 years, Martin Fowler and ThoughtWorks, British architect James Lewis, sat down together to analyze several large and complex systems that could continue to evolve, summarizing 9 core traits, It then uses microservices to define the architecture that holds these traits. Since then, Google, Netflix, Amazon and a range of star enterprises are the seat,
