DESCRIPTION

Very few trends in IT have generated as much buzz as cloud computing. This talk 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.

SOFTWARE AS A SERVICESingle application, multi-tenancy, network-based, one-to-many delivery ofapplications, all users have same access to features.Examples: Salesforce.com, Google Docs, Red Hat Network/RHELDEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICEApplication developer model, Application deployed to an elastic service thatautoscales, low administrative overhead. No concept of virtual machines oroperating system. Code it and deploy it.Examples: Google AppEngine, Windows Azure, Rackspace Site, Red HatMakaraSYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICEServers and storage are made available in a scalable way over a network.Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack,Eucalyptus, Ubuntu Enterprise Cloud, OpenNebula 7.
