在cloud foundry上开发JAVA应用

1、第一章CF介绍什么是 CloudFoundry Cloud Foundry是一个开源的PaaS云计算平台，它提供给开发者自由度去选择云平台，开 发框架和应用服务。Cloud Foundry最初由VMware发起，得到了业界广泛的支持，它使得开发者能够 更快更容易的开发，测试，部署和扩展应用。Cloud Foundry是一个开源项目，用户可以使用多种私有 云发行版，也可以使用公共云服务，包括CloudF ；CloudFoundry总体架构图1.3 MicroCloudFoundryMicro Cloud Foundry是在开发人员的Mac或PC上的虚拟机中运行的完整版CloudFoundry。它

2、是Cloud Foundry的完整实例，既能提供本地部署的灵活性，同时又为您提供将来部署和扩展应用程序的选择。Micro Cloud Foundry是一个可下载的虚拟机映像，与用于 MacOSX的VMware Fusion 及用于 Linux 和 Windows 的 VMware Workstation和 VMware Player （可免费下载）兼 容。它提供易于安装、设置和进行VM管理的机制。详细介绍请看 HYPERLINK /?p=74 /?p=741.4在线资源产品介绍 PPT： HYPERLINK http:/vdisk.weibo.Com/s/7k0Bo http:/vdisk.w
