  4. 4. What is cloud computing? Can I make 什么是云计算? What are money from they doing cloud with cloud computing? computing?我能利用云计算赚钱吗? CTO 大家都用云计算做什 Questions 么? ??? Why do I need What’s the cloud cost to computing in deploy cloud our computing? organization? What if I don’t 部署云计算很贵吗? adopt cloud 我为什么需要云计算? computing in our organization? 不部署云计算会怎么样? CIeNET PROPRIETARY 9/2/2012 4
  5. 5. Several FACTS we discovered that you may not know about yourorganization or also need to deal with …We have a lot of computers (我们有很多机器) • Server, Blade, Workstation, Desktop PC, Laptop PCComputer 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 utilizedComputer software installation is done manually (软件手动安装) • Repetitive work (repeated installations) and added overhead for IT maintenanceWe use a lot of commercial software licenses (好多商业软件!) • It’s expensiveWe’ve installed some virtualization software (已经尝试使用虚拟化软件) • Not centrally managed CIeNET PROPRIETARY 9/2/2012 5
  6. 6. Several CONSTRAINTS we are aware of which may also be yourconstraints …Lack disposable budget for new equipment (我们没有额外的预算) • Economic slowdown and increased efficiency demandsNeed for an increase in productivity and shorter TTM (需要提高效率缩短上市时间) • Competition!Reluctant to put all data in public cloud (数据暂时不想放在公有云里) • Security and IPR concerns and not ready for it yetLimited bandwidth for IT department (IT部门的工作已经非常饱和) • It’s all about costNeed rich applications for collaboration (企业协作需要更多的应用) • Enterprise 2.0 … CIeNET PROPRIETARY 9/2/2012 6

  10. 10. Embrace Cloud Computing: A Strategic Plan(拥抱云计算策略) 提供云服务 使用云服务 Provide cloud- based services to 开发环境 Deploy and use public cloud-basedIT 基础设施 Develop/test with services cloud platform CIeNET PROPRIETARY 9/2/2012 10
  11. 11. 3. Practices我们的实践 CIeNET PROPRIETARY 9/2/2012 11
  12. 12. Guideline: Don’t Over-Engineer in the Beginning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 9/2/2012 12
  13. 13. Re-use Resources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: 大量普通机器做存储  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 CIeNET PROPRIETARY 9/2/2012 13
  14. 14. The Infrastructure 我们搭建的基础设施 Users OpenStack IaaS SoftwareVirtualization KVM KVM KVM Compute Node Storage Node CIeNET PROPRIETARY 9/2/2012 14
  15. 15. Controller: HP DL380 Computer: DELL R510/ Storage: 980 DELL 980/990 /320CIeNET PROPRIETARY 9/2/2012 15
  16. 16. Software Version: 软件版本  Ubuntu 12.04 64-bit  Virtualization: QEMU-KVM-1.0  Openstack Essex Release  Controller  nova-network nova-api nova-volume  Compute Node  nova-network nova-api nova-compute  Storage  Swift Proxy, Swift Object, Swift Container, Swift CIeNET PROPRIETARY 9/2/2012 16
  17. 17. Beyond OpenStack: Put DevelopmentPlatform 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. Java Dev. Env. Android Compile Env. Dev. Config. Management Auto Test Framework CIeNET PROPRIETARY 9/2/2012 17
  18. 18. Beyond OpenStack: Develop Enterprise NetDisk Module 开发企业网盘模块 CIeDISK Module SaaS Software OpenStack IaaS SoftwareVirtualization KVM KVM KVM Compute Node Storage Node CIeNET PROPRIETARY 9/2/2012 18
  19. 19. CIeDISK Module: 我们开发的企业网盘-”瞬盘”模块  User File Management 基于用户的文件管理  Group Sharing 群组分享  Multiple Files Upload 多文件上传  Online Photo Gallery 在线照片库  MAC/Windows/Tablet Clients 多客户端 CIeNET PROPRIETARY 9/2/2012 19
  20. 20. Planning 规划 Computers Floating IP addresses  Allocate enough floating IP addresses for virtual machines Some issues we met  Partitioning:  We should give var and tmp partitions a large amount of space since var is used for instance disk and tmp is used for snapshot generation CIeNET PROPRIETARY 9/2/2012 20
  21. 21. Installation 安装 Manual Installation  With modified OpenStack installer script Chef/Puppet/JUJU are not used CIeNET PROPRIETARY 9/2/2012 21
  22. 22. Network 网络 Network Manager: VLAN We use 100Mb NIC Issues we met:  If floating IP and fixed IP are in same subnet, NAT translation will fail Some defects we met (but resolved in latest releases):  Floating IPs are not released  How: Terminate an instance and show floating lists  Resolve: Clean the floating IPs timely  Floating IP List shows Missing Instance  Reason: Delete zombie instance from database  Resolve: Set the delete status CIeNET PROPRIETARY 9/2/2012 22
  23. 23. Volume 卷 To save user data after VM is terminated Controller node needs to have enough disk space Some defects we met:  Cant create new volume:  According to the official document, tgt and iscsitarget should both be installed and started, but actually, they are conflicting services  Resolve: Stop iscsitarget CIeNET PROPRIETARY 9/2/2012 23
  24. 24. Resource Quota 资源限额 Balance between user needs and system performance The limits we set:  Virtual Machine:  Provide limited flavors: (CPU/RAM/Root Disk) cloud.large 2 1024 0 cloud.small 1 512 0 TAS.large 2 2048 15GB TAS.small 1 1024 15GB  Storage:  Per user quota: 1GB  File Size: < 50MB CIeNET PROPRIETARY 9/2/2012 24
  25. 25. Filtering and Scheduling 结点选择 Chance: With this method, a compute host is chosen randomly across availability zones  This is the default configuration, but will easily cause the system to be overloaded Simple: With this method, hosts whose load is least are chosen to run the instance  Choose this configuration CIeNET PROPRIETARY 9/2/2012 25
  26. 26. OA&M 监控管理 Zenoss  Physical node level, not inside VM CIeNET PROPRIETARY 9/2/2012 26
  27. 27. Operation Results 内部运营效果 Launched and running internally  Hardware resource utilization  10%  60%  Re-used old idle hardware  New development machine launch efficiency improved  4 hours  10 minutes  File/Picture sharing  Transactions increased by 30X quarterly  Personal space utilization  Average: 10% CIeNET PROPRIETARY 9/2/2012 27
  28. 28. OpenStack-based Infrastructure Summary关键点 OpenStack + New Modules + Customizations OpenStack + 新开发模块 + 定制化 Low cost 低成本 - Open source - Re-use existing, under-utilized hardware and old PCs Manageable 可管理 - Easy, Private, Secure, Full Control, and Extensible CIeNET PROPRIETARY 9/2/2012 28
