Now outdated - please see later cloud computing deck. http://www.slideshare.net/michaelharriescitrix/cloud-computing-and-citrix-c3-july-2009 This is a talk on Cloud Computing and the Citrix Cloud Center from Citrix iForum Sydney and Melbourne in May 2009. From time to time the Citrix CTO Office is asked to give presentations at these and other events. I'm interested in any/all feedback from the Citrix and Cloud communities.

1. Cloud computing and Citrix C3 June 2009 Feedback welcome -- Michael Cloud Computing and Citrix C3 Dr Michael Harries Citrix Labs © 2009 Citrix Systems, Inc. — All rights reserved

2. The term cloud computing has been much hyped in the recent past. Is it real or just hot air? Just hot air?

3. Indeed everyone seems to mean something different when they talk about cloud.

4. For one, the cloud graphic has long represented ‘any network’ connecting two computers.

5. Some see it as the culmination of a long line of contributing technologies. Virtualization Utility Computing WOA SOA AutonomicComputing SaaS BPM HPC PaaS IaaS ITIL Clustering Web 2.0 Data Mining RAC Mesh Grid 5

6. Others, like Nicholas Carr, have a ‘utopian’, user oriented view of cloud computing. Cheap, utility-supplied computing will ultimately change society as profoundly as cheap electricity did

7. Some vendors, like SalesForce, argue that cloud is the whole future of IT. Cloud is web based SaaS + web based, hosted dev platform

8. Others, like Google, define cloud as just – what they do. Google IS the cloud

9. For the end user, cloud is synonymous with a ‘nice web application’ Cloud is ease of use It’s every cool web page It’s Google mail It’s SaaS It’s EASY

10. For Enterprise IT, cloud promises to make IT ‘easy’ Cloud is flexibility of resources, available on demand Cloud is dynamically scalable Cloud is automated Cloud is IT nirvana!

11. But it’s just not that simple Cloud is not secure Loss of IT control Limited SLAs A Threat

12. So why so many disparate views? Cloud computing is an idea ‘made to stick’ Simple Unexpected Concrete Credible Emotional Stories

13. Here are some categories that help with thinking about cloud computing. Cloud Phase I Phase II Phase III Infrastructure as a Service Platform as a Service Software as a Service Azure

14. Citrix has offerings in each of these areas. Cloud Phase I Phase II Phase III Infrastructure as a Service Platform as a Service Software as a Service Citrix Online Citrix Cloud Center C3 Labs ... C3 labs is early stage, but is intended to become a “delivery platform as a service”

15. The area that has the most impact on Enterprise IT is Infrastructure as a Service. IaaS Infrastructure as a Service

16. At it’s core, IaaS is about bringing the economics of web companies to the enterprise

17. The most critical part of how this is achieved is through standardizing computing components. Standardization

21. 4TB of TIFFs

22. To 1.5TB of PDFs

24. Some emphasize base level virtualization – virtual servers, virtual storage, and virtual networks.

25. Others emphasize resource management, multi-tenancy (in all its forms), usage monitoring, and optimizing across the farm.

26. Still others are mainly about application management, which components work where, and how they need to interact.

27. And some are mainly about providing access and automation in the cloud.

28. So where does Citrix fit? And why does Citrix have any part of this discussion?

29. Citrix has long been about turning Windows applications into a service. In a very real sense, bringing delivery abstraction to every application. Where Does Citrix Fit? Citrix Delivery Center Delivering Enterprise IT as a Service XenDesktop · XenApp · NetScaler · XenServer

30. Citrix is also the fifth largest SaaS vendor globally with Citrix Software as a Service offerings.

31. 75% of Internet Users Each Day 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.

32. Xen and the Art of the Cloud Finally, Citrix Xen is broadly used and is the engine behind most large commercial clouds globally. Citrix is a major player in cloud computing. “ Xen Citrix XenServer Xen Citrix, Intel, AMD, IBM, HP, Fujitsu, Unisys, SGI, Samsung, Sun, VA Systems, Red Hat, Novell, VA Linux, DoD, NSA (42 orgs) ” 100% compatible with Microsoft Hyper-V

33. Citrix sees System Virtualization at the heart of the IaaS cloud revolution. Along with other industry major players we have been working to ensure cross compatibility of virtualization platforms. Virtualization

34. One major area for these efforts has been our involvement in the Distributed Management Task Force to enable the Open Virtualization Format standard. OVF is a standard way to express information about a given virtual appliance to allow automated import and execution on any virtualization platform. Open Virtualization Format => VM freedom

35. OVF = Multi-VM AppliancesCitrix Project Kensho OVF not only allows for virtual appliance portability, but also enables multi-VM Virtual appliances. Image: Trio of nested Klein bottles (source http://www.sciencemuseum.org.uk/images/I046/10314758.aspx)

36. Let’s get to the point. Citrix Cloud Center has caused some degree of confusion, but it’s actually pretty simple ... Citrix Cloud Center C3

37. C3 is the same technology that Citrix sells for the Enterprise, packaged for cloud scenarios, with a cloud appropriate pricing model. Citrix Delivery Center [but for the cloud]

38. Here’s a simple schematic showing how C3 might be deployed for cloud use (inside or outside the datacenter) Repeater NetScaler Workflow Studio XenApp XenDesktop cloud bridge XenServer

39. Recent additions to C3 include: A virtual appliance version of our celebrated NetScaler appliance. NetScaler VPX

40. Recent additions to C3 include: A virtual switch (announced but not yet released) Virtual Switch Company A Company C Company B

41. Recent additions to C3 include: XenApp and XenDesktop, as we’ve recognized that application delivery is an important cloud task. All of these contribute to the broader picture. Repeater NetScaler Workflow Studio XenApp XenDesktop cloud bridge XenServer

42. C3 Reference Architecture Here’s one way to think about IaaS cloud computing. Customer Application / VM Management Customer / Consumer App Transactions cloud bridge Workload Distribution System (grid engine) Web Application Delivery Fabric Virtual Server Containers Commodity Hardware Infrastructure Distributed Virtual Switch

43. C3 Reference Architecture And here’s how the Citrix Cloud Centercould be delivered in such an architecture. Customer Application / VM Management NetScaler MPX cloud bridge Workload Distribution System (grid engine) NetScalerVPX NetScalerVPX NetScalerVPX NetScalerVPX Repeater Web Application Delivery Fabric XenApp XenDesktop Virtual Server Containers Dynamic Workload Provisioning XenServer Commodity Hardware Infrastructure Distributed Virtual Switch

44. We’ve also recently announced a Service Provider program. Citrix Service Provider Program Citrix newest partner program Designed for service providers Monthly “active subscriber” pricing & licensing model Route-to-market for customers inclined to leverage hosted services

45. So what does all this enable? Enterprise cloud is about enabling enterprise to take advantage of web economies Enterprise Cloud

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. Disaster Recovery

47. The combination of cloud computing and the Citrix Delivery Center capabilities enables Windows applications to fully participate in the cloud. Windows Apps

48. “Cloud-burst” 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.

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. Bridge Apps in cloud; Data stays on premise

50. Citrix C3 Labs provides an easy way to explore these ideas at very low cost using Amazon EC2 Citrix C3 C3 Lab

51. We’ve provided blueprints (recipes) on the Citrix community site. Citrix C3 Lab Blueprints Common Scenarios Community Driven Architectural Overviews Deployment Guides Best Practices

52. Did I mention that it was easy? http://community.citrix.com/C3Lab

53. Citrix sees the Cloud as a direct evolution of the datacenter, and part of the future of every IT shop. Pay-go Automation Cloud-extended Data Center Data Center Virtualization Self-ServiceData Center Flexibility Dynamic Data Center Server Consolidation Economics Time

54. Cloud is not just hot air. Now is the time for exploration.
