Why client-side load balancers like Ribbon?

≯℡__Kan透↙ 提交于 2019-12-04 21:33:36
问题 Netflix makes use of Ribbon, which is in their terms a "client-side load-balancer". What are the use-cases and advantages of a client-side load-balancer compared to a traditional load-balancer? Is Ribbon, and other Netflix OSS services AWS -specific or can they be used in other contexts? 回答1: As already mentioned by using Ribbon you don't need an additional load balancer. You can also configure the balancing algorithm for each client differently, if you need to. At first I was a bit surprised

Unexplainable lack of performance improvement using RxJava Observables in Web Applications

问题 I am performing some tests to evaluate if there is a real advantage in using reactive API's based on Observables, instead of the blocking traditional ones. The whole example is available on Githug Surprisingly the results show that the thoughput results are: The best : REST Services that return a Callable / DeferredResult that wraps the blocking operations. Not that bad : Blocking REST Services. The worst : REST Services that return a DeferredResult whose result is set by a RxJava Observable

NetflixOSS Zuul Filter for rejecting requests

南笙酒味 提交于 2019-12-04 16:16:43
问题 I am trying to use a ZuulFilter in a simple spring-cloud-Netflix Api gateway (reverse proxy) in order to authenticate requests against a custom authentication provider (via Rest call). The Filter should reject unauthorized requests with a 401 and don't pass those requests further down to the proxied services. Is that even possible for a ZuulFilter? I did not find documentation, example or something in Zuuls api. Any suggestions? 回答1: I got this to work, took some digging. Make sure your

Combining Netflix Zuul with Netflix Hystrix

孤人 提交于 2019-12-04 13:44:37
I'm a big fan of the Open Source project of Netflix. They made some really cool stuff. I have set up a Zuul and that is working fine. Created all kind of filters and those are dynamically loaded and run. What I now try to do is use Hystrix inside a filter. What I see is that if everything when fine it all works. But when there is a exception inside the run() method Zuul is catching it instead of Hystrix. So the getFallback() is never called. I shared my code Github . Somebody has any idea how Hystrix can catch the exception instead of Zuul? I think the issue is actually with how you are

OAuth Callback procedure for mobile devices

帅比萌擦擦* 提交于 2019-12-04 09:51:52
I am designing a Netflix Application for BlackBerry mobile devices. I am currently working on the OAuth. I am at the point where I can generate a Netflix login page in an embedded browser field in my application. After the user signs in, Netflix will send the user from the login page to a specified callback url. The callback url will also contain an authorized token, which is then needed to send back to Netflix. My question is: How am I supposed to do this on a mobile device? Is there a procedure set in place? I am unsure how I can extract the authorized token from the callback URL and send it

spring cloud微服务分布式云架构 - Spring Cloud简介

我的梦境 提交于 2019-12-04 06:43:27
Spring Cloud是一系列框架的有序集合。利用Spring Boot的开发模式简化了分布式系统基础设施的开发,如 服务发现、注册、配置中心、消息总线、负载均衡、断路器、数据监控 等(这里只简单的列了一部分),都可以用Spring Boot的开发风格做到一键启动和部署。Spring Cloud将目前比较成熟、经得起实际考验的服务框架组合起来,通过Spring Boot风格进行再封装,屏蔽掉了复杂的配置和实现原理,最终整合出一套简单易懂、易部署和易维护的分布式系统架构平台。 有spring cloud b2b2c电子商务需求的朋友可以加企鹅求求:三五三六二四七二五九 Spring Cloud组成 Spring Cloud的子项目,大致可分成两类: 一类是对现有成熟框架Spring Boot的封装和抽象,也是数量最多的项目; 第二类是开发了一部分分布式系统的基础设施的实现,如Spring Cloud Stream就是kafka, ActiveMQ这样的角色。开发人员进行 微服务 的实践,第一类子项目就已经足够使用,如: Spring Cloud Netflix   是对Netflix开发的一套分布式服务框架的封装,包括服务的发现和注册,负载均衡、断路器、REST客户端、请求路由等。 Spring Cloud Config   将配置信息中央化保存, 配置Spring Cloud

Netflix Eureka and 2 instances of application on local environment

余生颓废 提交于 2019-12-03 20:37:12
I'm getting started with Netflix Eureka and using its 1.1.145 ( https://github.com/Netflix/eureka/tree/1.1.145 ) version. I want to start locally 2 instances of the same application on different ports and have them both registered with Eureka. I'm using sample service ( https://github.com/Netflix/eureka/blob/1.1.145/eureka-server/conf/sampleservice/sample-eureka-service.properties ) So I start Eureka itself and 2 instances using above config - one app on 8001 port and another on 8002. For some reason I'm getting only one instance registered with Eureka at any given time. Both of them start

How to use omniauth to make authenticated calls to services?

旧街凉风 提交于 2019-12-03 13:02:17
I've received a token / secret from a service using OmniAuth and can store it for users, but I'm stuck as to how to actually use these to call a service. The closest thing I've seen to this question is here but the way he's solved that there doesn't feel right. I feel like OmniAuth likely does this all for you if you know what you're doing. Netflix has a pretty involved auth process , so I was hoping to skirt all of this by using OmniAuth to abstract me from all of this. Given that I have a token and secret for a user, how to use these in calling a service like Netflix? Many thanks :) Hey, I'm
