Cloud Computing Expo West - Crash Course in Open Source Cloud Computing
Post on 11-May-2015
DESCRIPTIONVery 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.

Quick Cloud ComputingOverview: Or the ObligatoryWhat is the Cloud? Slides 5. 5Five Characteristics of Clouds 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.
