By introducing the underlying concepts beyond the core components, this practical guide will bootstrap your understanding of this service.Learn how to run Cloud Foundry in a highly available and secure environment, using a sound disaster-recovery policy based on the author’s frontline experience. This book removes the need to adopt a lengthy trial-and-error approach to deploying Cloud Foundry.
最近到spring的官网上转了一下，发现了这个新东西，试了一下，但是由于还在测试阶段，注册了Cloud <em>foundry</em>的账号需要一段时间才能收到回复。根据它的介绍，可以在web 应用中<em>使用</em>多种java框架，这个要比Google App Engine要令人兴奋得多，不废话了，下面是Cloud <em>foundry</em>的安装<em>使用</em>，由于刚刚才出来的，所以是英文的，凑合着看吧： By now you probably heard about Cloud Foundry, th
What exactly is a <em>cloud</em>-native platform? It’s certainly a hot topic in IT, as enterprises today assess this option for developing and delivering software quickly and repeatedly. This O’Reilly report explains the capabilities of <em>cloud</em>-native platforms and examines the fundamental changes enterprises need to make in process, organization, and culture if they’re to take real advantage of this approach.
Author Duncan Winn focuses on the open source platform Cloud Foundry, one of the more prominent <em>cloud</em>-native providers. You’ll learn how <em>cloud</em>-native applications are designed to be "infrastructure unaware" so they can thrive and move at will in the highly distributed and constantly evolving <em>cloud</em> environment.
With this report, you’ll explore:
Technical driving forces that are rapidly changing the way organizations develop and deliver software today
How key concepts underpinning the Cloud Foundry platform leverage each of the technical forces discussed
How <em>cloud</em>-native platforms remove the requirement to perform undifferentiated heavy lifting, such as provisioning VMs, middleware, and databases
Why <em>cloud</em>-native platforms enable fast feedback loops as you move from agile development to agile deployment
Recommended changes and practical considerations for organizations that want to build <em>cloud</em>-native applications
