  5. 5. $ What is Cloud Computing? VirtualizationCloud
  6. 6. Server Virtualization++ Cloud Built for traditional enterprise apps & client- server compute • Enterprise arch for 100s of hosts • Scale-up (server clusters) • Apps assume reliability • IT Mgmt-centric [1:Dozens] • Proprietary vendor stack Designed around big data, massive scale & next-gen apps • Cloud architecture for 1000s of hosts • Scale-out (multi-site server farms) • Apps assume failure • Autonomic [1:1,000’s] • Open, value-added stack Think: vCloud Director Think: AWS, RAX, zCloud, eBay, etc. …but adoption of new cloud architecture is the future Enterprises should, and will, make SV 1.0 more cloud-like… • 10x more scaleable • 2-5x lower cost • 100% more open
  7. 7. • Secure, multi-tenant cloud orchestration platform – Turnkey platform for delivering IaaS clouds – Hypervisor agnostic – Massively scalable, secure and open – Open source, open standards – Deploys on premise or as a hosted solution • Deliver cloud services faster and at a fraction of the cost $ What is CloudStack? Build your cloud the way the world’s most successful clouds are built
  8. 8. $ CloudStack Background • OpenSource IaaS platform, now underASL 2.0 license • A proven cloud platform – Developed since 2008 by Cloud.com – Acquired by Citrix in 2011 – Citrix donated toApache Software Foundation (ASF) in April 2012 – Version 4.2.0 available for download at http://cloudstack.apache.org/downloads.html – Powering some of the world’s largest clouds today.
