  • 1. Crash Course in OpenSource CloudComputingMark R. HinkleDirector, Cloud Computing CommunityCitrix Systems Inc.Twitter: @mrhinkleEmail: mrhinkle@gmail.com
  • 2. 2Agenda1.  Introduction2.  Quick Cloud Computing Overview3.  Open Source Building Blocks for Cloud Computing4.  Open Source Tools for Cloud Management5.  Questions
  • 3. 3%whoami•  Responsible for Driving Adoption of CloudStack Open Source Cloud Computing Software•  Joined Citrix via Cloud.com acquisition July 2011•  Former manager of Zenoss Open Source project 100,000 users, 1.5 million downloads•  Former Linux Desktop Advocate (Zealot?)•  Former LinuxWorld Magazine Editor-in-Chief•  Open Management Consortium organizer•  Author - “Windows to Linux Business Desktop Migration” – Thomson•  NetDirector Project - Open Source Con guration Management Project•  Sometimes Author and Blogger at SocializedSoftware.com/NetworkWorld
  • 4. Quick Cloud ComputingOverview: Or the Obligatory“What is the Cloud?” Slides
  • 5. 5Five Characteristics of Clouds1. On-Demand Self-Service2. Broad Network Access3. Resource Pooling4. Rapid Elasticity5. Measured Service
  • 6. 6Cloud Computing Service Models USER CLOUD a.k.a. SOFTWARE AS A SERVICE Single application, multi-tenancy, network-based, one-to-many delivery of applications, all users have same access to features. Examples: Salesforce.com, Google Docs, Red Hat Network/RHEL DEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICE Application developer model, Application deployed to an elastic service that autoscales, low administrative overhead. No concept of virtual machines or operating system. Code it and deploy it. Examples: Google AppEngine, Windows Azure, Rackspace Site, Red Hat Makara SYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICE Servers and storage are made available in a scalable way over a network. Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack, Eucalyptus, Ubuntu Enterprise Cloud, OpenNebula
  • 7. Deployment Models 7Public, Private & Hybrid Clouds
  • 8. Cloud Still Requires 8Architectural Design•  Cloud Computing isn’t a “magical solution”•  Need to design your architecture with the end in mind•  As you build it make your infrastructure easily replicable
  • 9. Building Compute Cloudswith Open Source Software
  • 10. 10Why Open Source?•  Typically User-Driven Solutions to Real Problems•  Larger user base, users helping users•  Lower barrier to participation•  Aggressive release cycles – stay current with the state-of-the-art•  Try before you “buy”, no Brochure-ware, no “Powerpoint software•  Open data, Open standards, Open APIs
  • 11. 11Open Virtual Machine FormatsOpen Virtualization Format (OVF) is an openstandard for packaging and distributing virtualappliances or more generally software to be runin virtual machines.An OVF package consists of several files, placedin one directory. A one-file alternative is the OVApackage, which is a TAR file with the OVFdirectory inside.
  • 12. Tools for Creating OSS VMs and 12Cloud Appliances
  • 13. 13Open Source HypervisorsOpen Source•  Xen, Xen Cloud Platform (XCP)•  KVM – Kernel-based Virtualization•  VirtualBox* - Oracle supported Virtualization Solutions•  OpenVZ* - Container-based, Similar to Solaris Containers or BSD Zones•  LXC – User Space chrooted installsProprietary•  VMware•  Citrix Xenserver•  Microsoft Hyper-V•  Oracle VM

  • 23. 23The Myth of the NinesAvailability % Downtime per Downtime per Downtime per Year Month Week99.9% (three nines) 8.76 hours 43.2 minutes 10.1 minutes99.95% 4.38 hours 21.56 minutes 5.04 minutes99.99% (four nines) 52.6 minutes 4.32 minutes 1.01 minutes99.999% ( ve nines) 5.26 minutes 25.9 seconds 6.05 seconds99.9999% (six nines) 31.5 seconds 2.59 seconds .0605 seconds Average polling interval for monitoring? 5 minutes? Even superhuman operations people can’t be alerted and take action in under 5 minutes. One outage per year could drop service level to three nines or worse.
