9. Cloud Computing is the solution What can be done?

10. Page  10 Defining Cloud Computing  Cloud metaphor for Internet – add computing  Many Cloud Computing definitions -differing opinions -one thing in common – Services provided via the Internet A Definition: Cloud computing encompasses any subscription-based or pay-per-use service that is offered in real time over the Internet

11. Page  11 Cloud Computing  Model for enabling convenient, on-demand network access to a shared pool of configurable computing resources like networks, server storage applications, and services that can be rapidly acquired, used and released with minimal management effort or service provider interaction.  Cloud Computing customers do not own the physical infrastructure rather they rent the usage from third party provider.  They consume resources as a service and pay only for resources that they use.  Sharing resources improves the speed of computing when the servers are unnecessarily left idle.

12. If yes, How ? Do you make use of Cloud computing?

13. Page  13 Google  Email  Maps  Text Translation  Google Docs Apple i-phone Microsoft Sharepoint  iPhone  iPad  Application platform

14. What does the Virtualized Desktop Infrastructure look like? Centralized Virtual Desktops Servers in Data Centre Clients Private Cloud Internet Workstation Thin Client Laptop Office Home Hotel (Roaming)

15. Devices Virtually Limitless... Your Desktop, Anywhere You Are As you move between devices, your desktop follows you! Your Desktop on a Thin Client Your Desktop on a SmartPhone Your Desktop on an AppleMac Your Desktop on a PC Anywhere Anytime Any Device Anywhere Anytime Any Device

17. Page  17  Complete application is offered to the customer, as a service on demand  Single instance of the service runs on the cloud and multiple end users are serviced  On the customers’ side, there is no need for upfront investment in servers or software licenses, thereby reducing costs Software as a Service (SaaS)

18. Page  18  A layer of software, or development environment is encapsulated & offered as a service, upon which other higher levels of service can be built  Customer has freedom to build his own applications which run on the provider’s infrastructure  PaaS providers offer a predefined combination of OS and application servers to meet manageability and scalability requirements of applications Platform as a Service (PaaS)

19. Page  19  Provides basic storage and computing capabilities as standardized services over the network  Servers, storage systems, networking equipment, data centre space etc. are pooled and made available to handle workloads  Customer free to deploy own software on the infrastructure Infrastructure as a Service (IaaS)

20. Page  20 Private Cloud: Cloud infrastructure deployed, maintained and operated for a specific organization. Cloud deployment models Community Cloud: Cloud infrastructure shared among a number of organizations with similar interests and requirements. Helps limit Capital expenditure as establishment costs are shared among the organizations... contd.

21. Page  21 Cloud deployment models Public Cloud: Cloud infrastructure available to public on a commercial basis by a cloud service provider. Enables a consumer to develop and deploy a service in the cloud with very little financial outlay compared to the capital Hybrid Cloud: Cloud infrastructure consists of a number of clouds of any type. Clouds have ability through their interfaces to allow data and / or applications to be moved from one cloud to another. Can be combination of private and public clouds that support the requirement to retain some data in an organization, and also the need to offer services in the cloud.

22. Benefits and Cost Savings Cloud computing

23. Page  23 Benefits of Cloud Computing

24. Page  24 More secure ChallengeVHW Benefit Theft Virtual Workstations centralized Roaming users and data loss Access centralized data Data encrypted Restrict users downloading to USB, CD and DVD drives from home, hotel and laptops Unauthorized access to sensitive data Physical access to data restricted as it resides in a secure data centre Access to sensitive data restricted through enforcement of permissions Users unsecurely connecting to data Complex password authentication

25. Page  25 Benefits of Cloud Computing

26. Page  26 Management and Support ChallengeVHW Benefit Manage and support multiple end user devices complex and time consuming Manage and support standard VD in data centre much simpler and more efficient Mix of Operating Systems: 2000, XP Pro, Vista … Standardization on all VD Different software versions Create one standard VD image with all applications preloaded e.g.: Office, Adobe Reader, QuickBooks, Simply Acct etc. Users more productive Time consuming to perform patch management and security updates Centralized management and support of VD Long wait time to resolve user issues Self healing - most issues can be resolved by logging off\on VD – takes less than 5 minutes

27. Page  27 Benefits of Cloud Computing

28. Page  28 Business Continuity and Disaster Recovery ChallengeVHW Benefit Back up failure Test restores performed Data backed up every 4hrs\ day \ week \ month \ year Data loss due to: user error corruption hard drive failure Quickly able to recover data therefore limiting downtime and lost productivity Distaster strikes and business continuity Quick and cost effective Data backed up and stored on multiple devices Devices stored in multiple locations

29. Page  29 Benefits of Cloud Computing

30. Page  30 Hardware and Licensing ChallengeVHW Benefit Purchasing hardware and licensing every 4 years – expensive Never purchase hardware and licensing again Lead time for hardware instant Obsolesence Never worry about upgading to the latest hardware\software version again Upgrade RAM and hard drives inefficient Very quickly add more RAM and hard drive space on the fly Space issue Frees up space on users desk Noise and heat Thin clients has significantly less noise and heat Heavy laptop Do not have to carry heavy laptop around – access anywhere, anytime

32. Cost savings - Total Cost of Ownership (TCO) 40% Reduction HW and SW costs 29% Reduction IT operations costs 88% Reduction worker downtime 78% Increase IT staff productivity Source: Gartner Inc (8/05), IDC (11/05)

33. How Green is it? Cloud computing

34. Page  34 Green benefits of Cloud Computing Servers  Virtualize therefore reduce # servers e.g. 5 to 10 virtual servers to 1 physical server  Less space required  Reduced power Workstations  Thin clients and hence reduced power – 8watts compared to 80watts  Virtual workstations running on servers – 30 to 70 wks to 1 server IT Support  Workstations that are not used are switched off  Maintenance performed real time Environmental  Lower carbon emissions – less power needed  Recycle / reuse old equipment
