What do you mean high availabilityHigh availability generally refers to the redundancy of services, a service is hung, can automatically switch to another service, does not affect the customer experience.High-Availability Registration centerIn a distributed environment such as the microservices architecture, we need to take full account of the failure situation, so that each component must be highly available for deployment in a production environment, as for microservices, and for service cente

1. Concept: Ribbon load Balancing2. Specific contentNow that all the services have been registered through Eureka, then the purpose of using Eureka registration is to want all the services to be unified into the Eureka processing, but now the problem, all the microservices into the Eureka, and the client's call should

discovery components, such as Eureka, zookeeper, and More.second, EurekaEureka is the Netflix open source service Discovery component, which is itself a rest-based service. It contains both server and client Parts. Spring Cloud integrates it into the subproject spring cloud Netflix to enable the registration and discovery of Microservices.2.1. write Eureka Server2.1.1 New Springboot ProjectCreate a new Spr

Spring Cloud Eureka is part of the spring cloud Netflix MicroServices Suite, which has two footprints based on Netflix Eureka and is primarily responsible for service governance capabilities in the MicroServices architecture. Spring Cloud adds spring boot-style automation to Eureka, and we only need to easily integrate the MicroServices applications built with sp

collection as an area. The AWS region allows AWS Cloud services to be geographically closer to our users, while allowing users to choose from different areas to store their data to meet local regulatory compliance requirements.Each region of the availability zone:aws is typically made up of multiple availability zones (AZ), and an availability zone typically consists of multiple data centers. AWS introduces an availability zone design primarily to improve the high availability of user applicati

Eureka, as the Spring Cloud service discovery and Registration center, is at the core of the entire microservices system. A single Eureka service, obviously can not meet the high availability of the actual production environment, which requires us to configure a variety of emergency situations, with strong capacity for disaster tolerance of Eureka services. Here

Before we build the project, let's take a look at the Eureka, which is an official explanation, and I'll look back at you for a moment:Service Discovery: Eureka ClientService discovery is one of the key principles of micro-service architecture. Trying to configure each client or some form of convention can be very difficult and very fragile. The Netflix service discovers that servers and clients are

On the road to Spring-cloud MicroServices (ii): Spring boot We showed you how to quickly build a microservices project using spring boot, which demonstrates how to use spring cloud Eureka and Spring Cloud C respectively Onsul complete the implementation of service registration and discovery. One: Service governance Service governance can be said to be the most core and basic module in MicroServices architecture, which is mainly used to realize the aut
