踏踏实实学习一点云计算的技术之Why OpenStack，尝试找出与网络设备的关系

为什么选择OpenStack

1. 可控和灵活 ，不会被某个厂商锁定，而且模块化的设计能把老旧、第三方的技术集成进来从而满足业务需要。Hypervisor支持微软的Haper-V， Citrix XenServer, Xen, KVM, VMWare ESX, LXC, QEMU, and UML.
2. 工业标准 ，来自于超过一打国家的60多家企业，包括Cisco，Citrix，Dell， Intel，以及微软参与到OpenStack的行动中，并且使用Openstack技术的云平台不断上线。
3. 被证明过的软件， 基于OpenStack的云操作系统已经被正在运营的大型公有云和私有云技术所验证。
4. 兼容性和可连接的， 使用此技术，未来方面迁移。

Why OpenStack

Control and Flexibility . Open source platform means you’re never locked to a proprietary vendor, and modular design can integrate with legacy or third-party technologies to meet your business needs. Hypervisor support for Microsoft Hyper-V, Citrix XenServer, Xen, KVM, VMWware ESX, LXC, QEMU, and UML.

Industry Standard . More than 60 leading companies from over a dozen countries are participating in OpenStack, including Cisco, Citrix, Dell, Intel and Microsoft, and new OpenStack clouds are coming online across the globe.

Proven Software . Running the OpenStack cloud operating system means running the same software that today powers some of the largest public and private clouds in the world.

Compatible and Connected . Compatibility with public OpenStack clouds means enterprises are prepared for the future—making it easy to migrate data and applications to public clouds when conditions are right—based on security policies, economics, and other key business criteria.
