Cloud Computing And Citrix C3

  1. 1. Cloud computing and Citrix C3<br />June 2009<br />Feedback welcome<br />-- Michael<br />Cloud Computing and Citrix C3<br />Dr Michael Harries<br />Citrix Labs<br />© 2009 Citrix Systems, Inc. — All rights reserved <br />
  2. 2. The term cloud computing has been much hyped in the recent past. Is it real or just hot air?<br />Just hot air?<br />
  3. 3. Indeed everyone seems to mean something different when they talk about cloud. <br />
  4. 4. For one, the cloud graphic has long represented ‘any network’ connecting two computers. <br />
  5. 5. Some see it as the culmination of a long line of contributing technologies.<br />Virtualization<br />Utility Computing<br />WOA<br />SOA<br />AutonomicComputing<br />SaaS<br />BPM<br />HPC<br />PaaS<br />IaaS<br />ITIL<br />Clustering<br />Web 2.0<br />Data Mining<br />RAC<br />Mesh<br />Grid<br />5<br />
  6. 6. Others, like Nicholas Carr, have a ‘utopian’, user oriented view of cloud computing. <br />Cheap, utility-supplied computing will ultimately change society as profoundly as cheap electricity did<br />
  7. 7. Some vendors, like SalesForce, argue that cloud is the whole future of IT.<br />Cloud is web based SaaS<br /> +<br />web based, hosted dev platform<br />
  8. 8. Others, like Google, define cloud as just – what they do. <br />Google IS the cloud<br />
  9. 9. For the end user, cloud is synonymous with a ‘nice web application’<br />Cloud is ease of use<br />It’s every cool web page<br />It’s Google mail<br />It’s SaaS<br />It’s EASY<br />
  10. 10. For Enterprise IT, cloud promises to make IT ‘easy’<br />Cloud is flexibility of resources, available on demand<br />Cloud is dynamically scalable<br />Cloud is automated<br />Cloud is IT nirvana!<br />
  11. 11. But it’s just not that simple<br />Cloud is not secure<br />Loss of IT control<br />Limited SLAs<br />A Threat<br />
  12. 12. So why so many disparate views? <br />Cloud computing is an idea ‘made to stick’<br />Simple<br />Unexpected<br />Concrete<br />Credible<br />Emotional<br />Stories<br />
  13. 13. Here are some categories that help with thinking about cloud computing.<br />Cloud<br />Phase I<br />Phase II<br />Phase III<br />Infrastructure as a Service<br />Platform as a Service<br />Software as a Service<br />Azure<br />
  14. 14. Citrix has offerings in each of these areas.<br />Cloud<br />Phase I<br />Phase II<br />Phase III<br />Infrastructure as a Service<br />Platform as a Service<br />Software as a Service<br />Citrix Online<br />Citrix Cloud Center<br />C3 Labs ...<br />C3 labs is early stage, but is intended to become a “delivery platform as a service”<br />
  15. 15. The area that has the most impact on Enterprise IT is Infrastructure as a Service.<br />IaaS<br />Infrastructure as a Service<br />
  16. 16. At it’s core, IaaS is about bringing the economics of web companies to the enterprise<br />
  17. 17. The most critical part of how this is achieved is through standardizing computing components. <br />Standardization<br />
  18. 18. f<br />One of the masters of such standardization is Amazon, with their Elastic Compute Cloud and Simple Storage Service. <br />The Amazon cloud has enabled a new wave of innovation.<br />Elastic Compute Cloud<br /><ul><li> from $0.10 per VM hour</li></ul>Simple Storage Service<br /><ul><li> $0.15 per gig stored
  19. 19. $0.17 per gig transferred</li></li></ul><li>Like virtual infrastructure by SmugMug, who have been able to scale tremendously without any of their own infrastructure through using Amazon Servers and Storage.<br />“30 employees. More than 300,000 paying customers. 288,000,000 photos.”<br />NO INFRASTRUCTURE<br />
  20. 20. And burst computing by the New York Times in converting historical images for use on a ‘retrospective’ web site. <br /><ul><li>New York Times
  21. 21. 4TB of TIFFs
  22. 22. To 1.5TB of PDFs
  23. 23. 100 EC2 Xen VMs</li></li></ul><li>Sound good so far? The trap is that every vendor has a different set of capabilities in mind when they utter the phrase “cloud computing”<br />
  24. 24. Some emphasize base level virtualization – virtual servers, virtual storage, and virtual networks.<br />
  25. 25. Others emphasize resource management, multi-tenancy (in all its forms), usage monitoring, and optimizing across the farm.<br />
  26. 26. Still others are mainly about application management, which components work where, and how they need to interact.<br />
  27. 27. And some are mainly about providing access and automation in the cloud.<br />
  28. 28. So where does Citrix fit?<br />And why does Citrix have any part of this discussion? <br />
  29. 29. Citrix has long been about turning Windows applications into a service. In a very real sense, bringing delivery abstraction to every application.<br />Where Does Citrix Fit? <br />Citrix Delivery Center<br />Delivering Enterprise IT as a Service<br />XenDesktop · XenApp · NetScaler · XenServer<br />
  30. 30. Citrix is also the fifth largest SaaS vendor globally with Citrix Software as a Service offerings. <br />
  31. 31. 75% of Internet Users Each Day<br />Citrix’s NetScaler technology is also very heavily used by Internet companies globally. To the extent that 75% of all Internet users touch our technology daily.<br />
  32. 32. Xen and the Art of the Cloud<br />Finally, Citrix Xen is broadly used and is the engine behind most large commercial clouds globally. <br />Citrix is a major player in cloud computing.<br />“<br />Xen<br />Citrix XenServer<br />Xen<br />Citrix, Intel, AMD, IBM, HP, Fujitsu, Unisys, SGI, Samsung, Sun, VA Systems, Red Hat, Novell, VA Linux, DoD, NSA (42 orgs)<br />”<br />100% compatible with Microsoft Hyper-V<br />
  33. 33. Citrix sees System Virtualization at the heart of the IaaS cloud revolution.<br />Along with other industry major players we have been working to ensure cross compatibility of virtualization platforms. <br />Virtualization<br />
  34. 34. One major area for these efforts has been our involvement in the Distributed Management Task Force to enable the Open Virtualization Format standard. <br />OVF is a standard way to express information about a given virtual appliance to allow automated import and execution on any virtualization platform.<br />Open Virtualization Format =&gt; VM freedom<br />
  35. 35. OVF = Multi-VM AppliancesCitrix Project Kensho<br />OVF not only allows for virtual appliance portability, but also enables multi-VM Virtual appliances. <br />Image: Trio of nested Klein bottles <br />(source <br />
  36. 36. Let’s get to the point.<br />Citrix Cloud Center has caused some degree of confusion, but it’s actually pretty simple ...<br />Citrix Cloud Center<br />C3<br />
  37. 37. C3 is the same technology that Citrix sells for the Enterprise, packaged for cloud scenarios, with a cloud appropriate pricing model.<br />Citrix Delivery Center <br />[but for the cloud]<br />
  38. 38. Here’s a simple schematic showing how C3 might be deployed for cloud use (inside or outside the datacenter)<br />Repeater<br /> NetScaler<br />Workflow Studio<br />XenApp<br />XenDesktop<br />cloud bridge<br />XenServer<br />
  39. 39. Recent additions to C3 include:<br />A virtual appliance version of our celebrated NetScaler appliance.<br />NetScaler VPX<br />
  40. 40. Recent additions to C3 include:<br />A virtual switch (announced but not yet released)<br />Virtual <br />Switch<br />Company A<br />Company C<br />Company B<br />
  41. 41. Recent additions to C3 include:<br />XenApp and XenDesktop, as we’ve recognized that application delivery is an important cloud task. All of these contribute to the broader picture. <br />Repeater<br /> NetScaler<br />Workflow Studio<br />XenApp<br />XenDesktop<br />cloud bridge<br />XenServer<br />
  42. 42. C3 Reference Architecture<br />Here’s one way to think about IaaS cloud computing.<br />Customer Application / VM Management<br />Customer / Consumer App Transactions<br /> cloud bridge<br />Workload Distribution System (grid engine)<br />Web Application Delivery Fabric<br />Virtual Server Containers<br />Commodity Hardware Infrastructure<br />Distributed Virtual Switch<br />
  43. 43.

  44. 44. We’ve also recently announced a Service Provider program.<br />Citrix Service Provider Program<br />Citrix newest partner program<br />Designed for service providers<br />Monthly “active subscriber” pricing & licensing model <br />Route-to-market for customers inclined to leverage hosted services<br />
  45. 45. So what does all this enable?<br />Enterprise cloud is about enabling enterprise to take advantage of web economies <br />Enterprise<br />Cloud<br />
  46. 46. An obvious possibility is to take images of all servers in the datacenterand be prepared to start them in the cloud in the case of a disaster. <br />Disaster Recovery<br />
  47. 47. The combination of cloud computing and the Citrix Delivery Center capabilities enables Windows applications to fully participate in the cloud.<br />Windows Apps<br />
  48. 48. “Cloud-burst”<br />An example of enterprise Cloud-burst might be when a physical XenApp farm is at its limit, the farm could be configured to automatically transfer new sessions to the cloud.<br />
  49. 49. In the scenario of running in the cloud, many want to keep data on premise – Citrix Branch Repeater provides a way to do this.<br />Bridge<br />Apps in cloud; Data stays on premise<br />
  50. 50. Citrix C3 Labs provides an easy way to explore these ideas at very low cost using Amazon EC2<br />Citrix C3<br />C3 Lab<br />
  51. 51. We’ve provided blueprints (recipes) on the Citrix community site.<br />Citrix C3 Lab Blueprints<br />Common Scenarios<br />Community Driven<br />Architectural Overviews<br />Deployment Guides<br />Best Practices<br />
  52. 52. Did I mention that it was easy?<br /><br />
  53. 53. Citrix sees the Cloud as a direct evolution of the datacenter, and part of the future of every IT shop.<br />Pay-go<br />Automation<br />Cloud-extended Data Center<br />Data Center Virtualization<br />Self-ServiceData Center<br />Flexibility<br />Dynamic Data Center<br />Server Consolidation<br />Economics<br />Time<br />
  54. 54. Cloud is not just hot air. Now is the time for exploration. <br />
