  • 2. 2%whoami•  Responsible for Driving Adoption of CloudStack Open Source Cloud Computing Software•  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 Conspirator•  Open Desktop Consortium Instigator•  Author - “Windows to Linux Business Desktop Migration” - Thomson•  NetDirector Project - Open Source Con guration Management Project•  Sometimes Author and Blogger at SocializedSoftware.com/NetworkWorld•  Start-up junkie, Glutton for punishment
  • 3. 3Agenda•  Cutting Through the Cloud Computing Hype•  Open Source Building Blocks for Cloud Computing•  Open Source Tools for Cloud Management•  Questions (and Hopefully Answers)
  • 4. Cloud Computing:Cutting throughthe Hype
  • 5. 5Cloud Computing Adoption•  365,000 web sites are running on Amazon EC2 - Netcraft May 2010•  £76 billion spent on Cloud Computing in the U.K. in 2010 - IT Candor•  Cloud Computing will be a $126 billion market by 2012 - IBM•  20% of Businesses won’t have IT Assets by 2012 - Gartner•  December 2010,Amazon Web Services housed 262 billion objects, more than doubling in size from 102 billion objects at the close of 2009 - Amazon
  • 6. 6Open Source Virtual Adoption•  41% of users prefer to deploy servers virtually, 29.3% use virtualization whenever possible•  Xen is 2nd most popular virtualization technology after VMware followed by Linux Kernel-Based Virtual Machines (KVM) with 21.3% of the market•  49.2% of users planed to deploy hosted Linux servers in 2010 while 32.6% indicated that they would be deploying hosted Microsoft Windows.•  50.8% indicated they used no specific management tools for cloud computing, 33.3% indicated using tools provided by their hosting provider Source: Zenoss Cloud Computing State of the Union - http://www.zenoss.com/in/virtualization_survey.html
  • 7. 7Five Characteristics of Clouds1. On-Demand Self-Service2. Broad Network Access3. Resource Pooling4. Rapid Elasticity5. Measured Service
  • 8. 8Cloud 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

Even superhuman operations people can’t be alerted and take action in under 5 minutes. One outage per year could drop service level to three nines or worse.
