摘要：Swift是OpenStack的对象存储模块，Keystone是OpenStack的权限验证模块。可以于这两个模块搭建一个较为完善的云存储系统。1、官方方案云存储的服务器分三种类型：验证节点 Auth node – 运行 Auth service (keystone )代理节点 Proxy node – 运行 Proxy services存储节点 Storage node – 运行 Account, Container, and Object services此方案是官方文档上的方案，部署图如下：此方案中，有1个Proxy node ，运行 swift-proxy-server。 proxy 阅读全文

摘要：OpenStack Object Storage（Swift）是OpenStack开源云计算项目的子项目之一，被称为对象存储，提供了强大的扩展性、冗余和持久性。 Swift并不是文件系统或者实时的数据存储系统，它称为对象存储，用于永久类型的静态数据的长期存储，这些数据可以检索、调整，必要时进行更新。最适合存储的数据类型的例子是虚拟机镜像、图片存储、邮件存储和存档备份。因为没有中心单元或主控结点，Swift提供了更强的扩展性、冗余和持久性。Swift前身是Rackspace Cloud Files项目，随着Rackspace加入到OpenStack社区，于2010年7月贡献给OpenStack，作为该开源项目的一部分。 阅读全文

摘要：Components of OpenStackOpenStack is on a mission: to provide scalable, elastic cloud computing for both public and private clouds, large and small. There are currently seven core components of OpenStack: Compute, Object Storage, Identity, Dashboard, Block Storage, Network and Image Service.• Object 阅读全文

摘要：In data centers today, many computers suffer the same under-utilization利用不足 in computing power and networking bandwidth. For example, projects may need a large amount of computing capacity to complete a computation, but no longer need the computing power after completing the computation. You want cl 阅读全文

摘要：OpenStackOpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.1、OpenStack Co 阅读全文
