Cloud Computing Expo West - Crash Course in Open Source Cloud Computing


Published on

Very few trends in IT have generated as much buzz as cloud computing. This session will cut through the hype and quickly clarify the ontology for 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 complimentary 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 at their disposal to effectively build and manage their own cloud computing environments using free and open source software.

  5. 5. 5Five Characteristics of Clouds
  6. 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:, 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

  8. 8. Cloud Still Requires 8Architectural Design• Cloud Computing isn’t a magical solution apps need to be able to scale out• Design your architecture with the end in mind• Make your infrastructure easily replicable
  9. 9. Building Compute Cloudswith Open Source Software
  10. 10. 10Why 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
  11. 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. • • • • •

  15. 15. 15Scale-Up or Scale-Out• Vertical Scaling (Scale-Up) – Allocate additional resources to VMs, requires a reboot, no need for distributed app logic, single-point of OS failure• Horizontal Scaling (Scale-Out) – Application needs logic to work in distributed fashion (e.g. HA-Proxy and Apache, Hadoop)
