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 ObligatoryWhat 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 isnt 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 14. 14Open Source Compute Clouds Year Started License HypervisorsSupported 2008 GPL Xen Cloud Platform, XenCloud Platform, KVM,VMware 2008 GPL Xen, KVM, VMware 2010 ApacheVMware ESX and ESXi, (Developed byMicrosoft Hyper-V, Xen, NASA by Anso KVM and Virtual Box Labs peviously) Other open source compute software include Abiquo and OpenNebula Numerous companies are building cloud software on OpenStack including Nebula, Piston Inc. 15.

Aggressively Developed, Keep Pace with State-of-the- Art User-Developed and Instrumented Easy to Assemble into Automated Toolchains 22. 22What Makes Tools Cloudy? Network Capable Cloud Aware Easy-to-Integrate Adhere to Open Standards Lend Themselves to Automation 23. 23The Myth of the NinesAvailability % Downtime per Downtime per Downtime per Year MonthWeek99.9% (three nines)8.76 hours 43.2 minutes 10.1 minutes99.95% 4.38 hours 21.56 minutes5.04 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 cant be alerted and take action in under 5 minutes.One outage per year could drop service level to three nines or worse. 24. 244 Types of Management ToolsProvisioningInstallation of operating systems and other softwareConfiguration ManagementSets the parameters for servers, can specifyinstallation parameters Orchestration/Automation Automate tasks across systemsMonitoringRecords errors and health of IT infrastructure 25. 25Management ToolchainsToolchain (n): MonitoringA set of tools wherethe output of one Patching andProvisioningtool becomes theinput of another tool Con guration 26.
