前言前面我已经把 MySQL 的专题系列都更新完了，相信大家看了之后应该都有很大的收获（应该没有夸张吧哈哈哈哈），毕竟把 MySQL 通讲了一遍，出去面试应该也能够说比一般面试官知道得多了，在工作中性能调优的理论知识也基本上具备了（也建议大家多实践，实践出真知）。废话不多说，今天这个篇章是非专题系列，主要是给大家梳理一下关于架构方面的东西，希望大家看完之后能对服务器架构方面有一定的了解，也感谢大家一直以来的支持。正文架构的本质一个软件系统随着功能越来越多，调用量急剧增长，整个系统逐渐碎片化，越来越无序，最终无法维护和扩展，所以系统在一段时间的野蛮生长后，也需要及时干预，避免越来越无序。架构的本质就是对系统进行有序化重构，使系统不断进化。那架构是如何实现无序到有序的呢？基本的手段就是分和合，先把系统打散，然后重新组合。<br /> 分的过程是把系统拆分为各个子系统 / 模块 / 组件，拆的时候，首先要解决每个组件的定位问题，然后才能划分彼此的边界，实现合理的拆分。<br /> 合就是根据最终要求，把各个分离的组件有机整合在一起，相对来说，第一步的拆分更难。 <br />拆分的结果使开发人员能够做到业务聚焦、技能聚焦，实现开发敏捷，合的结果是系统变得柔性，可以因需而变，实现业务敏捷。架构的分类架构一般可分业务架构、应用架构、技术架构：

问题 I've a springboot app hosted on PCF trying to connect to PCC(pivotal cloud cache). I've spinned up a PCC instance and binded it to my app and pushed the app to cloud foundry. I've added all the required gemfire starter dependencies to springboot and it appears like it was able to read the locator and server information from VCAP_SERVICES. But, I see the following error on spring boot app startup. org.apache.geode.cache.client.internal.ConnectionFactoryImpl.createClientToServerConnection

是时候给大家介绍 Spring Boot/Cloud 背后豪华的研发团队了

我们刚开始学习 Spring Boot 的时候肯定都会看到这么一句话： Spring Boot 是由 Pivotal 团队提供的全新框架，其设计目的是用来简化新 Spring 应用的初始搭建以及开发过程。这里的 Pivotal 团队肯定就是 Spring Boot 的研发团队了，那么这个 Pivotal 团队到底是个什么来头呢？和 Spring 又有那些关系？不着急且听我慢慢道来。要说起这个 Pivotal 公司的由来，我得先从 Spring 企业的这条线来说起。 Spring 的发展时间回到 2002 年，当时正是 Java EE 和 EJB 大行其道的时候，很多知名公司都是采用此技术方案进行项目开发。这时候有一个美国的小伙子认为 EJB 太过臃肿，并不是所有的项目都需要使用 EJB 这种大型框架，应该会有一种更好的方案来解决这个问题。他为了证明自己的想法是正确的，在 2002 年 10 月写了一本书《Expert One-on-One J2EE》，介绍了当时 Java 企业应用程序开发的情况，并指出了 Java EE 和 EJB 组件框架中存在的一些主要缺陷。在这本书中，他提出了一个基于普通 Java 类和依赖注入的更简单的解决方案。在书中，他展示了如何在不使用 EJB 的情况下构建高质量、可扩展的在线座位预留系统。为了构建应用程序，他编写了超过 30,000
