7. Virtualization Virtualization, refers to the act of creating a virtual (rather than actual) version of something. Virtualization is the simulation of the software and/or hardware upon which other software runs. NIST SP 800-125 Tunis, Tunisia, 28 April 2014 7

8. 8 Virtualization Stack Network Storage OS Applications Desktop virtualization Virtualization helps implement Cloud Computing

9. Network virtualization Virtualize one hardware network equipment into many virtual network equipments Virtualize many hardware into one virtual network equipment (consolidate) Layer 2&3 technologies Tunis, Tunisia, 28 April 2014 9

10. External/internal network virtualization Tunis, Tunisia, 28 April 2014 10

11. Network virtualization benefits Improve network resource usage Internal : traffic between VMs through vNICs External : many networks without the need to build many physical Improve security : isolate traffic based on groups : e.g. isolate depts Tunis, Tunisia, 28 April 2014 11

12. What is storage virtualization Making abstraction separating : Host implementation (application, OS) Network implementation (switch, router, gateway) Storage implementation (array, library, device) Make invisible to host : physical pathing, device characteristics, physical data location Location and implementation transparency Tunis, Tunisia, 28 April 2014 12

13. Storage virtualization stack Tunis, Tunisia, 28 April 2014 13 SNIA storage stack

14. Storage virtualization benefits Increase storage asset utilization Reduce power / cooling costs Reduce management complexity Openness to server, network and storage technology Reduce down time Dynamic provisioning (elastic cloud, on demand) Increase scalability Tunis, Tunisia, 28 April 2014 14

15. OS virtualization NIST definition : Full virtualization Virtualization is the simulation of the software and/or hardware upon which other software runs. NIST SP 800-125 Each OS appears to have : CPU, memory, storage (hard disk, USB, CD-ROM,…storage controller, Ethernet controller, display and sound, keyboard and mouse, parallel ports, … Tunis, Tunisia, 28 April 2014 15

16. Types of OS virtualization Tunis, Tunisia, 28 April 2014 16 NIST SP 800-125

17. Benefits of OS virtualization Consolidation : reduce CAPEX Efficiency : Rise hardware usage Flexibility : reduce management and OPEX costs Security : Isolation prevent : Avoid crash DDOS attacks Side channel Attacks Weakness : hypervisor is SPOF if compromised all is down. Tunis, Tunisia, 28 April 2014 17

18. Hardware Dispersed deployment and maintenance, local storage Traditional desktop infrastructure: hard to maintain, can not guarantee security and lacks mobility. Complex O&M Security risk Difficult to service Page 18

19. Huawei desktop cloud platform Hardware Creates a reliable and scalable shared resource pool to perform unified management. Decouples hardware from the OS to perform central delivery. Decouples applications from the OS to perform central delivery. Decouples data from the OS to perform central storage. Creates multi-level security systems to perform distributed security control. User interface (UI) is transmitted to terminal devices by using remote protocols, such as ICA, RDP, or PCoIP. User equipment only includes a keyboard, a mouse and a monitor Desktop Cloud solution Data storage center Application delivery center Desktop delivery center Security management center Page 19

20. Application virtualization Application virtualization layer to run specific software (layer replaces the run time environment) Separate applications from OS The container will ensure OS security allows applications to run in environments that do not suit the native application: e.g. Wine allows some Microsoft Windows applications to run on Linux. Tunis, Tunisia, 28 April 2014 20

21. Virtualization technology facilitates the implementation of cloud computing 5/22/2015 21

22. Cloud computing Model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction NIST SP-500-291 5/22/2015 22

23. Characteristics On-demand self-service Broad network access Resource pooling Rapid elasticity Measured service 5/22/2015 23

24. Cloud Ecosystem/actors 5/22/2015 24

25. Cloud Cost model Traditional licensing associated with ownership, number of users, support, and maintenance costs and services are being challenged by the pay-as-you-go model found in on- demand Cloud Computing 5/22/2015 25

26. Capacity management 5/22/2015 26

27. ROI/Cost saving 5/22/2015 27 Opengroup

28. Rapid provisioning : TTM impact on ROI 5/22/2015 28 Opengroup

29. Increase Margin 5/22/2015 29 Opengroup
