LinuxFest Northwest: Crash Course in Open Source Cloud Computing


Published on

Few IT trends have generated as much buzz as cloud computing. This talk will cut through the hype and clarify cloud computing. The bulk of the conversation will focus on the open source software that can be used to build compute clouds (infrastructure-as-a-service) and the complementary open source management tools that can be combined to automate the management of cloud computing environments. The discussion will appeal to anyone who has a good grasp of traditional data center infrastructure but is struggling with the benefits and migration path to a cloud computing environment. Systems administrators and IT generalists will leave the discussion with a general overview of the options for building and managing their own cloud computing environments using free and open source software.

  5. 5. Quick Cloud Computing Overview:Or the Obligatory “What is theCloud?” Slides
  6. 6. 6Five Characteristics of Clouds
  7. 7. 7Cloud 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:, 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: VMware CloudFoundry, Google AppEngine, Windows Azure, Rackspace Sites, Red Hat OpenShift, Active State Stackato, Appfog 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, OpenNebula

  12. 12. 12Why Open Source?• User-Driven Solutions to Real Problems• Lower barrier to participation• Larger user base, users helping users• Aggressive release cycles stay current with the state- of-the-art• Open data, Open standards, Open APIs
  13. 13. 13Open Virtual Machine FormatsOpen Virtualization Format (OVF) is an openstandard for packaging and distributing virtualappliances or more generally software to be runin virtual machines. • • • • •
