  4. 4. Cloud Computing - The Coming StormWhat is Cloud Computing?• Cloud computing is a technology that uses the internet and central remoteservers to maintain data and applications. Cloud computing allows consumersand businesses to use applications with internet access.• Data can be Accessed via Internet anywhere from world without installation of any software or server.• User Centric – Easier for group members to collaborate• Task Centric – User’s need is more important than features of application• Powerful – All resources together create a wealth of computing power• Programmable – Automated distribution of computing power and dataPricewaterhouseCoopers across cloud. Data loss become a history now Slide 4
  5. 5. Cloud Computing - The Coming StormWhat Cloud Computing “IS NOT”?• It is not Network Computing  Application and Data are not confined to any specific Company’s Server  No VPN Access  Encompasses multiple companies, multiple servers and multiple networks• It is not Traditional Outsourcing  Not a contract to host data by 3rd party Hosting Business  No subcontracting for computing services for specific outside firmPricewaterhouseCoopers Slide 5
  6. 6. Cloud Computing - The Coming StormSo exactly what Cloud Computing is?• A style of computing where massively scalable IT-enabled capabilities are provided "as a service" over the network Business Model Usage Based Access Model Network Technical Model DynamicCloud ComputingPricewaterhouseCoopers Slide 6
  7. 7. Cloud Computing - The Coming StormEvolution of Cloud Computing Cloud Computing SaaS Computing  Next-Generation Utility Computing  Network-based Internet Grid Computing Offering subscriptions computing Solving large to applications  Next-Generation computing problems with resources as a Gained Data Centers Parallel metered momentum computing service in 2001 Made  Introduced in mainstream late 1990s By Global AllianceCloud ComputingPricewaterhouseCoopers Slide 7

  13. 13. Cloud Computing - The Coming StormSoftware as a Service (SaaS)• Applications (word processor) or application services (schedule, calendar, etc.) execute in the “cloud” using the interconnectivity of the internet to propagate data• Custom services are combined with 3rd party commercial services via orchestration to create new applications• Requires investment to build an enabling layer with governance, security and data management functionality• May require integration with back-office systems• Pay-as-you-go model SaaS will disrupt the application management functions for both internal IT and outsourcersCloud ComputingPricewaterhouseCoopers Slide 13
  14. 14. Cloud Computing - The Coming StormWhat are the benefits & challenges of SaaS? Benefits Challenges • Speed • Extension of the security model • Reduced up-front cost, potential to the provider (data privacy and for reduced lifetime cost ownership) • Transfer of some/all support • Governance and billing obligations management • Elimination of licensing risk • Synchronization of client and vendor migrations • Elimination of version • Integrated end-user support compatibility • Reduced hardware footprint • Scalability Strong governance required to prevent lines of business from purchasing application services externally without IT involvementCloud ComputingPricewaterhouseCoopers Slide 14
  15. 15. Cloud Computing - The Coming StormPlatform as a Service (PaaS)• Applications are built in the “cloud” on the platform using a variety of technologies• Simplifies orchestration of cloud services• Development, testing, and production environments (servers, storage, bandwidth, etc.) are billed monthly like hosting• Pay-as-you-go model• Environments scale up & down at the click of a button• Concerns include code & data privacy, security and scalability PaaS will disrupt the application development and management functions for internal ITCloud ComputingPricewaterhouseCoopers Slide 15
  16. 16. Cloud Computing - The Coming StormWhat are the benefits & challenges of PaaS? Benefits Challenges• Pay-as-you-go for development, • Governance test, and production environments • Tie-in to the vendor• Enables developers to focus on • Extension of the security model to application code the provider• Instant global platform • Connectivity• Elimination of H/W dependencies and capacity concerns• Inherent scalability• Simplified deployment model Strong governance required to prevent lines of business from building applications without IT involvementPricewaterhouseCoopers Slide 16
  17. 17. Cloud Computing - The Coming StormInfrastructure as a Service (IaaS)• Compute resources (processors, memory, storage, bandwidth, etc.) are provided in an as-needed, pay-as-you-go model• Able to provide from single server up to entire data centers• Creates new opportunities such as Cloud bursting: shifting usage spike traffic to alternate resources• Infrastructure scales up and down quickly to meet demand• Built on a utility computing architecture to host a SOA application layer IaaS will disrupt the infrastructure management functions for both internal IT and outsourcersCloud ComputingPricewaterhouseCoopers Slide 17
  18. 18. Cloud Computing - The Coming StormWhat are the benefits & challenges IaaS? Benefit Challenges • Higher return on assets through • Portability of applications higher utilization • Reduced cost driven by • Maturity of systems • Less hardware management tools • Less floor space from smaller • Integration across the Cloud hardware footprint boundary • Higher level of automation • Extension of internal security from fewer administrators models • Lower power consumption • Able to match consumption to demand IaaS is the onramp for corporate IT to Cloud Computing!Cloud ComputingPricewaterhouseCoopers Slide 18
  19. 19. Why should we care - The gathering stormPossibilities of Cloud Computing • Increases business responsiveness • Accelerates creation of new services via rapid prototyping capabilities • Reduces acquisition complexity via service oriented approach • Uses IT resources efficiently via sharing and higher system utilization • Reduces energy consumption • Handles new and emerging workloads • Scales to extreme workloads quickly and easily • Simplifies IT management • Platform for collaboration and innovation • Cultivates skills for next generation workforceCloud ComputingPricewaterhouseCoopers Slide 19
  20. 20. Why should we care - The gathering stormWhat are the Cloud Computing opportunities?• Next evolutionary step in computing with >30yrs of momentum• Requires a new way of thinking, new processes, new skills, and new tools• Enables the business to work around IT departments• Companies will reduce IT operating costs and improve agility• Clients should consider cloud computing as part of their blueprint refresh, application rationalization, and outsourcing activities• Client should investigate cloud strategies with their systems management, application and outsourcing vendors Cloud Computing will meet prime time in the 2010 timeframeCloud ComputingPricewaterhouseCoopers Slide 20

  22. 22. The Storm is ComingSummary• Cloud Computing is an organizing principle for buyers• Focus is on faster, cheaper, better applications• IT will have to enable the company to use outside providers then compete with them to provide services• New models will emerge to drive growth and reduce costs• Get educated first, identify pilot opportunities second• Software as a Service is the short term opportunity, Infrastructure as a Service the long term, Platform as a Service has limited valuePricewaterhouseCoopers Slide 22
