 <h2>Java RMI Introduction</h2>
 <p>Java RMI (Remote Method Invocation) is a mechanism that allows users to access or invocate an object and a method running on another JVM (Java Virtual Machine). RMI is an implementation of RPC (Remote Procedure Call) in java with support of OOP (Object Oriented Paradigms). Instead of bothering IDL (Interface Define Language), users can build distributed applications by depending on interfaces in an easy and natural way.</p>

 <p>By studying this article, the reader can master the basic concepts of <code>Dubbo</code>'s exclusive <code>annotations</code> , <code>@EnableDubbo</code>, <code>@Service</code>, <code>@Reference</code>, and master it's basic usage through a simple <code>Dubbo</code> application.</p>
 <p>In addition to traditional <code>XML</code> configuration, <code>Spring</code> offers more modern configurations such as annotation drivers, externalization, and auto-assembly.This article focuses on the development of <code>Dubbo</code> applications through annotations. You can be seen that annotation mode programming is more concise and simple than XML configuration. In future, we will introduce the use of externalization configuration and automatic assembly in <code>Dubbo</code>  f [...]

 <p>Dubbo's provider don't care about service registration.Open its Dubbo service port,the declaration and publishment of the service will be executed by Kubernetes.
 Dubbo's consumer directly discovers the corresponding service endpoints of Kubernetes during service discovery procedure, thereby reusing Dubbo's existing microservice channel capabilities.The benefit is that there is no need to rely on any third-party soft-loaded registry and it can be seamlessly integrated into the multi-tenant security system of Kubernetes.

 If you don't know much about the dubbo protocol and want to understand how it works, the project provides a sub-moudle: java-socket-consumer, which is implemented in a process-oriented approach, realizing a process of sending dubbo protocal message with native socket and making function calls, and then get response.</p>

 <p>Dubbo is claimed as a high-performance RPC framework on its official website. Today, I want to talk about another great specialty of Dubbo --- its scalability.  As quote: Rome wasn’t built in a day. Any successful system always starts as a prototype. It is impossible to design a perfect system at the beginning. Instead, we should focus on true demand and keep improving the system. On the coding side, it requires us to pay attention on abstraction layers and high-level isolation. In th [...]

 <p>After using Dubbo to serve or integrate applications, assuming that a service backstage log shows an exception and that the service is invoked by multiple applications, it is often difficult to determine which application is called, and what is the cause of the problem, so we need a set of distributed tracking systems to quickly locate the problem. Pinpoint can help us quickly locate problems (of course, there are more than one solution).</p>

 <p>In large clusters there may be thousands of Dubbo service instances in production, with continuous traffic coming in. However, in distributed systems, some services may be unavailable due to various of failure such as traffic surge, high system load, and network latency. If no control actions are performed, this may cause cascading failure, affecting the availability of the service. So we need a powerful library - Sentinel, which can guarantee the stability of the service, to protect  [...]

 <p>You can run Demo Provider and Demo Consumer only, the default discovery strategy is Multicast by configuration center broadcast, do not run the two parts on the same machine, if you have to do so, set <code>unicast=false</code>, like <code>multicast://224.5.6.7:1234?unicast=false</code>, or the unicast send to consumer will be taken by provider, and the same for consumers. Only multicast has this issue</p>
 <p>You can run multiple Demo Provider and Demo consumer to verify load balance. Demo Consumer can run multi instance directly. Because of port conflict, you can either run multi Demo Providers on different machines or modify the value of <code>dubbo.protocol.port</code> in <code>conf/dubbo.properties</code> under the install directory of <code>conf/dubbo.properties</code></p>
 <p>You can add Simple Monitor as a monitor center, the default discovery strategy is Multicast by configuration center broadcast, display the dependency relationship, call times and cost</p>
 <p>You can use Zookeeper instead of Multicast as the configuration center, after Zookeeper Registry installation, modify <code>conf/dubbo.properties</code> under the installation directory of Demo Provider, Demo Consumer and Simple Monitor, change the value of <code>dubbo.registry.address</code> to <code>zookeeper://127.0.0.1:2181</code>(<code>redis://127.0.0.1:6379</code> for Redis Registry). the value for Simple Registry is <code>dubbo://127.0.0.1:9090</code></p>
 <p>Zookeeper configuration address is recommended</p>

 <p>After using Dubbo to serve or integrate applications, assuming that a service backstage log shows an exception and that the service is invoked by multiple applications, it is often difficult to determine which application is called, and what is the cause of the problem, so we need a set of distributed tracking systems to quickly locate the problem. Pinpoint can help us quickly locate problems (of course, there are more than one solution).</p>
 <h2>What is Pinpoint</h2>
 <p><a href="https://github.com/naver/pinpoint">Pinpoint</a> is an APM (Application Performance Management) tool for large-scale distributed systems written in Java. Inspired by Dapper, Pinpoint provides a solution to help analyze the overall structure of the system and how components within them are interconnected by tracing transactions across distributed applications.</p>

 <p>Dubbo's protocol, communication, serialization, registry, load balancing and other SPI all offer alternative strategies for different application scenarios while our test cases are very scattered. Ours is always uncertain whether it can satisfy the complete contract of the extension point when users need to add a new implementation.</p>
 <p>Thus we need to use TCK (Technology Compatibility Kit) for the core extension points.  When users add a new implementaion, compatibility with the rest of the framework can be ensured with TCK. This can effectively improve the overall health and also facilitate the access of the third party extenders, which accelerates the maturity of the open source community.</p>
 <p>Xingzhi from the open source community is already working on this part. His preliminary idea is to build a TCK framework for Dubbo drawing on the CDI-TCK of JBoss first, then realize the TCK implementing case of Dubbo.</p>

 <p>If you need, you can also consider placing a spring reference configuration in the API package, so that the user can only use the configuration in the spring loading process, and the configuration suggestion is placed in the package directory of the module, so as not to conflict, eg:<code>com/alibaba/china/xxx/dubbo-reference.xml</code>。</p>

 <h2>Call</h2>

 <p>When using rpc, the client usually only the interface, but sometimes the client also want to perform part of the logic in the client. For example: do ThreadLocal cache, verify parameters, return mock data when call fails., etc.</p>
 <p>To solve this problem, you can configure the stub in the API, so that when the client generates the proxy instance, it passes the proxy to the <code>Stub</code> via the constructor <sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>, and then you can implement your logic in the stub implementation code.</p>

 <p>When there are more and more vertical applications, the interaction between applications is inevitable, some core businesses are extracted and served as independent services, which gradually forms a stable service center,this way the front-end application can respond to the changeable market demand more quickly. At this point, the distributed service framework (RPC) for business reuse and integration is the key.</p>
 <h4>Flow computing architecture</h4>
 <p>When there are more and more services, capacity evaluation becomes difficult, and also services with small scales often causes waste of resources. To solve these problems, a scheduling center should be added to manage the cluster capacity based on traffics and to improve the utilization of the cluster. At this time, the resource scheduling and governance centers (SOA), which are used to improve machine utilization, are the keys.</p>

 <p><strong>Then, the traffic becomes even heavier, the capacity problem of the service is exposed, how many machines are needed to support this service? When should the machine be added?</strong> To solve these problems, first, the daily service calls and the amount of response time should be counted as a reference for capacity planning. Second, dynamically adjust the weight, increase the weight of an online machine, and recorded the response time changes until it reaches the threshold,  [...]

 <p>Spring 除了传统的 XML 配置之外,还提供了注解驱动、外部化配置、以及自动装配等更现代的配置方式。本文专注在介绍通过注解方式来开发 Dubbo 应用,可以看到,与 XML 配置相比,注解方式编程更加简洁明快。在今后的博文中,会进一步的介绍在 Dubbo 中使用外部化配置、以及自动装配的方法。</p>

 如同罗马不是一天建成的,任何系统都一定是从小系统不断发展成为大系统的,想要从一开始就把系统设计的足够完善是不可能的,相反的,我们应该关注当下的需求,然后再不断地对系统进行迭代。在代码层面,要求我们适当的对关注点进行抽象和隔离,在软件不断添加功能和特性时,依然能保持良好的结构和可维护性,同时允许第三方开发者对其功能进行扩展。在某些时候,软件设计者对扩展性的追求甚至超过了性能。</p>

 <h2>Apache Skywalking(Incubator)简介</h2>
 <p><a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a> 专门为微服务架构和云原生架构系统而设计并且支持分布式链路追踪的APM系统。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a>通过加载探针的方式收集应用调用链路信息,并对采集的调用链路信息进行分析,生成应用间关系和服务间关系以及服务指标。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking (Incubating)</a>目前支持多种语言,其中包括<a href="https://github.com/apache/incubator-skywalking">Java</a>,<a href="https://github.com/OpenSkywalking/skyw [...]
 <p>目前Skywalking已经支持从6个可视化维度剖析分布式系统的运行情况。总览视图是应用和组件的全局视图,其中包括组件和应用数量,应用的告警波动,慢服务列表以及应用吞吐量;拓扑图从应用依赖关系出发,展现整个应用的拓扑关系;应用视图则是从单个应用的角度,展现应用的上下游关系,TopN的服务和服务器,JVM的相关信息以及对应的主机信息。服务视图关注单个服务入口的运行情况以及此服务的上下游依赖关系,依赖度,帮助用户针对单个服务的优化和监控;调用链展现了调用的单次请求经过的所有埋点以及每个埋点的执行时长;告警视图根据配置阈值针对应用、服务器、服务进行实时告警。</p>

 <p>Dubbo 的协议,通讯,序列化,注册中心,负载均策等扩展点,都有多种可选策略,以应对不同应用场景,而我们的测试用例很分散,当用户自己需要加一种新的实现时,总是不确定能否满足扩展点的完整契约。</p>
 <p>所以,我们需要对核心扩展点写 <a href="http://en.wikipedia.org/wiki/Technology_Compatibility_Kit">TCK</a> (Technology Compatibility Kit),用户增加一种扩展实现,只需通过 TCK,即可确保与框架的其它部分兼容运行,可以有效提高整体健状性,也方便第三方扩展者接入,加速开源社区的成熟。</p>
 <p>开源社区的行知同学已着手研究这一块,他的初步想法是借鉴 JBoss 的 CDI-TCK,做一个 Dubbo 的 TCK 基础框架,在此之上实现 Dubbo 的扩展点 TCK 用例。</p>

 <p>前面不停的提到代码被其他人修改,这也开发人员要随时紧记的。这个其他人包括未来的自己,你要总想着这个代码可能会有人去改它。我应该给修改的人一点什么提示,让他知道我现在的设计意图,而不要在程序里面加潜规则,或埋一些容易忽视的雷,比如:你用 null 表示不可用,size 等于 0 表示黑名单,这就是一个雷,下一个修改者,包括你自己,都不会记得有这样的约定,可能后面为了改某个其它 BUG,不小心改到了这里,直接引爆故障。对于这个例子,一个原则就是永远不要区分 null 引用和 empty 值。</p>
 <h2>提高代码的可测性</h2>
 <p>这里的可测性主要指 Mock 的容易程度,和测试的隔离性。至于测试的自动性,可重复性,非偶然性,无序性,完备性(全覆盖),轻量性(可快速执行),一般开发人员,加上 JUnit 等工具的辅助基本都能做到,也能理解它的好处,只是工作量问题。这里要特别强调的是测试用例的单一性(只测目标类本身)和隔离性(不传染失败)。现在的测试代码,过于强调完备性,大量重复交叉测试,看起来没啥坏处,但测试代码越多,维护代价越高。经常出现的问题是,修改一行代码或加一个判断条件,引起 100 多个测试用例不通过。时间一紧,谁有这个闲功夫去改这么多形态各异的测试用例?久而久之,这个测试代码就已经不能真实反应代码现在的状况,很多时候会被迫绕过。最好的情况是,修改一行代码,有且只有一行测试代码不通过。如果修改了代码而测试�
 �例还能通过,那也不行,表示测试没有覆盖到。另外,可 Mock 性是隔离的基础,把间接依赖的逻辑屏蔽掉。可 Mock 性的一个最大的杀手就是静态方法,尽量少用。</p>

 <h2>配置向后兼容</h2>
 <p>向前兼容很好办,你只要保证配置只增不减,就基本上能保证向前兼容。但向后兼容,也是要注意的,要为后续加入新的配置项做好准备。如果配置出现一个特殊配置,就应该为这个“特殊”情况约定一个兼容规则,因为这个特殊情况,很有可能在以后还会发生。比如:有一个配置文件是保存“服务=地址”映射关系的,其中有一行特殊,保存的是“注册中心=地址”。现在程序加载时,约定“注册中心”这个Key是特殊的,做特别处理,其它的都是“服务”。然而,新版本发现,要加一项“监控中心=地址”,这时,旧版本的程序会把“监控中心”做为“服务”处理,因为旧代码是不能改的,兼容性就很会很麻烦。如果先前约定“特殊标识+XXX”为特殊处理,后续就会方便很多。</p>

 <p>在大规模服务化之前,应用可能只是通过 RMI 或 Hessian 等工具,简单的暴露和引用远程服务,通过配置服务的URL地址进行调用,通过 F5 等硬件进行负载均衡。</p>
 <p><strong>当服务越来越多时,服务 URL 配置管理变得非常困难,F5 硬件负载均衡器的单点压力也越来越大。</strong> 此时需要一个服务注册中心,动态的注册和发现服务,使服务的位置透明。并通过在消费方获取服务提供方地址列表,实现软负载均衡和 Failover,降低对 F5 硬件负载均衡器的依赖,也能减少部分成本。</p>
 <p><strong>当进一步发展,服务间依赖关系变得错踪复杂,甚至分不清哪个应用要在哪个应用之前启动,架构师都不能完整的描述应用的架构关系。</strong>  这时,需要自动画出应用间的依赖关系图,以帮助架构师理清理关系。</p>
 <p><strong>接着,服务的调用量越来越大,服务的容量问题就暴露出来,这个服务需要多少机器支撑?什么时候该加机器?</strong>  为了解决这些问题,第一步,要将服务现在每天的调用量,响应时间,都统计出来,作为容量规划的参考指标。其次,要可以动态调整权重,在线上,将某台机器的权重一直加大,并在加大的过程中记录响应时间的变化,直到响应时间到达阈值,记录此时的访问量,再以此访问量乘以机器数反推总容量。</p>
 <p>以上是 Dubbo 最基本的几个需求。</p>
