  1. What Is “The Cloud”? Terje Vangbo COO, Handel IT

  2. Theme Song for Cloud Computing I really don’t know clouds at all: …..I've looked at clouds from both sides now; From up and down, and still somehow It's cloud's illusions I recall; I really don't know clouds at all….. JUDY COLLINS - Both Sides Now - 1967

  4. History of Computing • 1951 - First Commercial Computer (UNIVAC 1) • 1964 – IBM 360 & DEC PDP 8 • 1976 - Apple 1 • 1981 – IBM PC & MS Dos • 1984 – Apple McIntosh • 1985 – MS Windows • 1989 – WWW Invented by Tim Berners-Lee • 1993 – Internet Usage Exploded • Today – Internet Expanding, Social Media and Cloud Computing

  5. Evolution of Computing • 1950 – 1965 • Computer Centers – Punched Cards and Paper Tape and Magnetic Tape Input • 1965 – 1985 • Computer Centers and In-House Computers • Mainframes (IBM 370) and Mini Computers (DEC VAX & IBM S34/S36/S38/AS400) – “Green Screen” Input • 1985 – 1995 • PCs and Windows Increasingly Used as User Interface • Today • Internet, Cloud Computing, Internet Browser, PCs, Cell Phones, Tablets – Input and Output

  6. Cloud Computing

  7. Cloud Computing • Cloud computing is location-independent computing, whereby shared servers provide resources, software, and data to computersand other devices on demand, as with the electricity grid. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them. Wikipedia

  8. Cloud Computing • Cloud Computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams. SearchCloudComputing.com

  9. Cloud Computing • A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic-- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the customer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.

  10. Cloud Computing Cloud computing is on-demand access to virtualized IT resources that are: – Housed outside of your own data center – Shared by others (multi-tenant) – Simple to use – Paid for via subscription – Accessed over the Web (John Foley, InformationWeek)

  11. Attributes of Cloud Computing Based on services Scalable and elastic Shared Metered by use Uses Internet technologies from “Gartner Highlights Five Attributes of Cloud Computing”

  12. Cloud Computing • What has made it possible? • The Internet!

  13. Hosted Solution/ SaaS/Cloud Computing • Cloud computing is always a hosted solution • Cloud computing is always SaaS • SaaS is always a hosted solution • SaaS is always cloud computing • A hosted solution is not always a SaaS • A hosted solution is not always cloud computing

  14. SaaS vs. Hosted Solution Does it matter for you as a user/customer if it is a hosted solution or a pure SaaS model? - Utilizes web browser and Internet - Solution hosted by vendor - Single - as apposed to multi-tenant - Pricing may not be as elastic – may still be very competitive - Use may not be as scalable and elastic

  15. Reasons for Using Cloud Computing • Business agility • No or limited term commitment • Limited or no upfront cost or investment • Time to solution • Reduced cost • Pay per use at “economy of scale” prices • Capabilities • Elasticity – scale up and shrink down • Out-of-the-box availability • Automated management • World-wide access • Risk transfer

  16. Reasons for Not Using Cloud Computing • Custom infrastructure requirements • e.g., high-speed interconnect • Regulatory compliance • Standards, audits, physical access • Security • Physical data stored off-site • Shared environment • No tolerance for performance variance • Shared environment

  17. Seven Cloud-Computing Security Risks • Privileged user access • Regulatory compliance • Data location • Data segregation • Recovery • Investigative support • Long-term viability Gartner, June, 2010 "Assessing the Security Risks of Cloud Computing."

  18. SaaS Today Payroll E-mail SFA Accounting End User

  19. SaaS Tomorrow Accounting SFA Payroll E-mail 401K SaaS Aggregator ERP SCM Super Aggregator New Business Processes, Not Possible Earlier, Will Be Possible Open Up to Business Partners End User

  20. SaaS Tomorrow • SaaS Aggregator – AppExchange by Salesforce.com • “Super” SaaS Aggregator – Perfect for telecom carriers looking for value-added services instead of providing just pipes: British Telecom, Qwest Convergence of IT & Telecom

  21. “Truth in Advertising” • “The Cloud” or “Cloud Computing” are hot marketing terms • Lots of offerings are advertised as cloud computing which are really not • Hosted solutions are more common today than cloud computing • Lots of hosted solutions are advertised as cloud computing

  22. Cloud for Consumers • E-mail Services • G-mail, Yahoo-mail, Hot-mail • Internet Services • Google, Yahoo, AOL, Amazon, Netflix, YouTube, Turbo Tax, Realtor.com, Travel sites, • Social Media • Facebook, Linked-in, My Space

  23. Cloud for Businesses/Non Profits • Salesforce.com • QuickBooks Online • Microsoft BPOS

  24. What Sectors Are Leading in Cloud Computing and SaaS? • The home businesses and small office sectors are leading the adoption of cloud-computing services, with business spending on cloud services predicted to surpass $13 Billion by 2014. - Smarthouse – Marie Jones

  25. What Sectors are Leading in Cloud Computing and SaaS • "The professional services and healthcare verticals will see the largest growth in spending on cloud computing services, growing over 124 percent  between 2010 and 2014." - Smarthouse – Marie Jones

  26. But There Is Lots More Going On in the

  27. PaaS & IaaS • The big battle of large players • All about domination! • Who can “own” the cloud?

  28. Domination of “The Cloud” • Applications • Individual Applications • SaaS Aggregators • Super Aggregators • Platform • Application Development • Service Delivery • Infrastructure • Communication • Processing • Storage

  29. PaaS - Key Players • Amazon.com (E2C) • Microsoft (Windows Azure) • Google (App Engine) • Salesforce.com

  30. IaaS – Key Players • Amazon.com (AWS) • Rackspace • IBM (Blue Cloud Data Center) • EMC (Atmos) • ZenitInfotech • GreenHouse Data

  31. Changing Environment External Conditions External Conditions Agile Organizations Process E H Process B G D Process I F Process A C Agile Computing IT Resources and Applications Provided When Needed and as Much as Needed

  32. Survival It is not the strongest of the species that survives… nor the most intelligent that survives. It is the one that is the most adaptable to change. – Charles Darwin

  33. It Is OK ………and necessary to have your head in “The Cloud!” Thank You to: Yoshi Noguchi, President & CEO, InterBusiness Corporation
