microservices fundamentals

BEA unveiled its Infrastructure software optimization plan on 19th to cater to the service-oriented Architecture (SOA) adopted by enterprise customers. The company's three main product lines-aqualogic, WebLogic and tuxedo-will eventually use the same software base, called "MicroServices architecture". The Service Oriented architecture is the architecture of the application software as a set of internally connected components or services. SOA is desig

Objective Before, I have said a lot about the concept of micro-services, after all, many people will see after the idea of no meaning, because there is no practical thing to say, even if each concept is understood, it is difficult to give practice. So this time, let me illustrate with a practical example of how we will build our microservices in the actual project process. PS: We just use the scene to simulate the entire process of our

distributed : Different modules deployed on different serversRole: Distributed to solve the problem of high concurrency of the site cluster : Multiple servers deploy the same application to form a clusterRole: Common external services through load balancing equipment SOA: The business system is decomposed into multiple components, allowing each component to independently provide discrete, autonomous, reusable service capabilities that enable top-level business processes through a combination o

When the circuit breaker opens, the main logic of the fuse, Hystrix will start a sleep time window, in this time window, the demotion logic is temporary into the primary logic, when the sleep time window expires, the circuit breaker will enter the semi-open state, release a request to the original master logic, if the request returned normally, Then the circuit breaker will continu

API Gateway is a very important part of the microservices architecture, there are many different services provided to external use, API gateway can be a unified portal, can also be done on the gateway for protocol conversion, permission control and request statistics and limit flow and other workSpring-cloud encapsulates the open source API gateway implemented by Netflix Zuul, and we can easily launch an instance of a Zuul gateway, support registering

Let's explore how

Product mouth of a small project, from project to development on-line, with time and demand of the continuous explosion, will become more and more complex, become a large project, if the previous project structure is not well designed, code will become more and more bloated, difficult to maintain, late every product iteration on the line will be reaching. Project MicroServices, loosely coupled with the relationship between the modules, is a good choic
