This document discusses using OpenStack to build a private cloud infrastructure for enterprise use. It argues that OpenStack is the best choice because it is open source, actively developed by a large community, and has a simple architecture. The company implemented OpenStack using existing server hardware and customized it to integrate internal development platforms and workflows. This improved resource utilization, development efficiency, and enabled new services like a cloud-based file sharing system. The private cloud deployment increased server utilization within the company from 10% to 60% and helped reuse older hardware.

4. Why Private IaaS?
内部调研发现：
We have a lot of computers （我们有很多机器）
• Server, Blade, Workstation, Desktop PC, Laptop PC
Computer resource utilization is low （每台机器的使用率很低）
• Average utilization < 10%
Old computers are idle （旧机器闲置）
• They are put aside rather than being utilized
R&D environment setup is repeated manually （研发环境手动重复安装）
• Repetitive work (repeated installations) and added overhead for IT maintenance
We use a lot of commercial software licenses （好多商业软件！）
• It’s expensive
We’ve installed some virtualization software （已经尝试使用虚拟化软件）
• Not centrally managed

5. Why OpenStack?
Open Active Simple
CIeNET PROPRIETARY 11/28/2012 5

6. Open
 从第一天起就是开源的. Apache 2.0 License (商业友好)
 不像Eucalyptus.
 Mar. 2012 Merge proprietary version with open source version
(GPL V3)
 不像CloudStack (Citrix).
 April 2012: donate to Apache Foundation
 对企业价值：
 Low Cost
 Fully Control (避免被商业软件公司Lock in)
 Free Re-distribution
CIeNET PROPRIETARY 11/28/2012 6

7. Active
 Participants: 190+ Companies
 Successful usage by large companies （如新浪）
 New established OpenStack Foundation
 对企业价值：
 More support from the community
 More features
 Clear and long-term roadmap 长期保护IT投资
CIeNET PROPRIETARY 11/28/2012 7

8. Simple
 Several available packages for enterprise adaptation:
 Rackspace, Red Hat, Ubuntu
 容易上手：Good documentation, more shared information from
community
 容易安装：Puppet, Chef, Crowbar,Juju …
 功能清晰：Virtual Machine (=EC2) + Object Storage ( = S3)
 对企业价值：
 降低对专家的依赖
 减少运维成本
 减少培训成本

13. 指导原则：初始阶段不要过度设计
 We don’t buy extra hardware: 没有购买新硬件
 Not all applications need a powerful CPU and large memory to
support high transaction rates.
 We haven’t implement HA：暂不实施高可用
 Not all applications need 24x7 availability.
 We only backup data for controller nodes: 仅备份控制节点
 Not all data need extremely high security.
 We don’t engineer for extremely concurrent usage of all
users: 不考虑所有用户同时使用等极端情况
 Not all user will use the system at same time
CIeNET PROPRIETARY 11/28/2012 13

14. 已有资源利用
 High End Computers: 少数“中高端”机做控制节点和计算节点
 Control Node and Computing Node
 EG:
 DELL R510, Xeon E5 2420 1.9G, 16G RAM, 500G * 7, 1Gb NIC
 HP DL380, 2 4-core Intel® Xeon® X5550，16GB RAM，1Gb NIC
 Low End Computers: 普通机器做存储
 Storage
 EG：
 DELL 980/990, Intel i5 3.20GHz 4G RAM 500G * 4, 100Mb NIC
 DELL 320, Intel Core2 1.80GHz 2G RAM 80G * 10, 100Mb NIC

Platform Inside 整合内部开发平台
 Make internal development and testing environment as a
standard image.
 Developers can now easily access a development environment
with just the push of a button. All dependent software is
included. （开发者点击鼠标就能获得想要的开发环境）
 Make environment management very easy.
