CloudFoundry + OpenStack: Your Own Platform

Building you own robust cloud platform with CloudFoundry and OpenStack

PaaS 概念近年来在国内是越来越火了，随着OpenStack 的日渐成熟，无论是在企业级抑或是创业公司来说其普及率越来越高，似乎再考虑搭建云平台时不将OpenStack 考虑在那觉得有些out的感觉。Mesos on top of OpenStack、 K8S on top of OpenStack, 以及自研的产品 on top of OpenStack,… 似乎OpenStack 这一开源领域的os 的说法越来越多的被这些案例所证实。但真的是这样么？在其它的分享中会再谈下我自己的看法。
此博客（可以说是一系列）初衷是将我近年来在OpenStack 以及CloudFoundry 所做的事做个总结，也为那些在PaaS产品选型以及在PaaS 这条路上刚入门的同学一些指导，如何通过这2个开源产品构建一个Out of Box 的Platform以及解决在使用过程中遇到的一些坑

平台初见 — Hello, World

‘Hello, World’ – 对于每一个干IT的人来说并不陌生，让我们看下在PaaS里面的HelloWorld 是什么样的。

1. 如果你是刚刚接触PaaS的童鞋， 对PaaS 可能会很陌生，究竟它有什么特点，我怎么用呢？

很简单， 简单的一个push 命令就可以将站点发布.

如果你想了解这和OpenStack是怎么关联起来的， 让我们看下这个

没错，这些实例就构成了PaaS 平台， 你可能会疑问api，cc-bridge, blabla, ….这些都是什么啊？ 没关系，这些组件在之后都会有说明.

到目前为止还没有提到OpenStack啊.
让我们看一张这个图

这张图很熟悉了吧，从这里可以看到所有创建出来的VM 信息.
再看一下网络图谱图

相信到目前为止已经对OpenStack 和CloudFoundry 有了初步的感受，再接下来的文章里，会介绍如何step-by-step搭建这样的一套云平台
